The $999 Hellhound RX 7900 XTX arrived at BTR for evaluation last week from PowerColor. We have been comparing it against Nvidia’s new $1199 RTX 4080 Founders Edition (FE) and $1599 RTX 4090 FE plus five additional top cards. We focus on raw performance by benchmarking 42 PC and 10 VR games, GPGPU, workstation, SPEC, and synthetic benchmarks.

We will also compare the performance of these three new competing cards with the RX 6900 XT and RX 6800 XT reference editions and their competitors, the RTX 3080 Ti and RTX 3080 FE.

Features & Specifications

Although launched at reference $999 XTX pricing, the Hellhound RX 7900 XTX has its factory Game Clock set 30MHz higher than the reference version’s 2300MHz. According to PowerColor specifications, the Hellhound RX 7900 XTX can boost its Game Clock to 2330MHz (2270MHz Silent) with the OC BIOS. The Game Clock is the expected GPU clock while running average high-load gaming scenarios with a regular non-overclocked total graphics usage situation. However, the GPU Boost Clock can reach as high as 2525MHz – 25MHz higher than reference – by using the OC BIOS and we will test this.

Here are the Hellhound RX 7900 XTX features.

Additional Information from PowerColor

• The Hellhound has 2 modes, OC and Silent with a BIOS switch on the side of the card. Even on performance mode it’s said to be considerably quieter than reference board and the silent mode is indeed very quiet.
• The 14 layer high TG PCB board has 12+3+2+2+1 Phase VRM design. Hellhounds are over-spec’d in order to deliver the best stability and overclocking headroom. By having high quality VRMs, it will run cooler and last longer.
• DrMos and high-polymer Caps are used without compromise.
• The cooler features three 9-blade ball bearing fans with 8 heat pipes (8X6?) across a high density heatsink with a copper base. The PCB is shorter than the cooler.
• It uses mute fan technology and the fans stop under 60C.
• The Hellhound RX 7900 XTX includes card stands for supporting it so as to not put extra strain on the PCIe slot.

The RX 7900 XTX is AMD’s brand new RDNA 3 flagship card, and the Hellhound represents one of the best choices for a mildly factory overclocked $999 card by virtue of its high-quality components and carefully selected GPUs coupled with good support and great warranty service.

The Test Bed

We benchmark using FCAT VR and FrameView on Windows 11 Pro Edition 2H22 with Intel’s Core i9-13900KF, and 32GB of T-Force Delta RGB 6400MHz CL40 DDR5 2x16GB memory on an ASUS Prime-A Wi-Fi Z790 motherboard with fast SSD storage. All games and benchmarks are patched to their latest versions, and we use recent drivers.

First, let’s take a closer look at the new PowerColor Hellhound RX 7900 XTX.

A Closer Look at the PowerColor Hellhound RX 7900 XTX

Although the Hellhound RX 7900 XTX advertises itself as a premium 24GB card which features ray tracing, Radeon Boost, and Anti-Lag, the cover of the box uses almost no text in favor of stylized imagery.

The back of the box touts key features which include ray tracing, Anti-Lag, DisplayPort 2.1, RDNA 3, FidelityFX, Infinity Cache, streaming aids, and Boost, as well as states its 800W power and system requirements. There is no mention of VR Ready Premium. Also highlighted are PowerColor’s custom cooling solution, Dual-BIOSes, fan improvements, and output LEDs. The default LED color is an eye-pleasing amethyst.

We open the box and note there are parts for a card stand.

The complete package contents except for the anti-static bag are pictured above together with the card holder parts. Above the stand is fully assembled. Although the Hellhound is relatively heavy, it is not 4090-heavy, and we didn’t feel a need for it.

The Hellhound RX 7900 XTX is a large tri-fan card in a three slot design which is quite handsome with PowerColor’s neutral colors and even more striking with the LED on.

Turning it over we see a sturdy backplate featuring the Hellhound logo which also lights up with amethyst being the default color.

Looking at either long edge, we see the entire PCB is covered by heatpipes and heatsink fins. Additional power is provided by the PSU’s 2 x 8-pin Molex cables to the card connectors. There is also a switch to choose between the default overclock (OC) BIOS and the Silent BIOS. We didn’t bother using the Silent BIOS as the card is really quiet anyway, but it is good to have in case a flash goes bad.

The card should perhaps be locked down with two thumbscrews instead of one because it is heavy or the stand can be used.

The Hellhound’s IO panel connectors include 3 DisplayPorts and 1 HDMI connection.

Below is the other end which is very plain.

The Hellhound RX 7900 XTX looks great inside a case.

The specifications look good and the card itself looks solid. Now let’s check out its performance after we look over our test configuration and more on the next page.

Overclocking, temperatures and noise

We spent little time overclocking the Hellhound RX 7900 XTX for this review as we encountered some unexpected results that require further investigation. The card is very quiet and its fans never spin up even under a heavy load so as to be irritating or even noticeable. It’s quieter than the Gigabyte 6900 XT or the RTX 3080 Ti.

The Hellhound RX 7900 XTX is factory clocked 30MHz higher than the reference version at 2330MHz using the OC BIOS. According to its specifications, the Hellhound boost can clock up to 2565MHz out of the box. From our benching, we generally see it boosting even higher and it generally settles in above 2750MHz with peaks above 2780MHz.

The Hellhound temperatures stay in the low to mid-60s C with the fans quietly running well below 50% even using the OC BIOS under a full gaming load. It is an exceptionally well-cooled and quiet card.

Let’s head to the performance charts to compare the performance of the Hellhound RX 7900 XTX with six other cards.

The Hellhound RX 7900 XTX vs. the RTX 4080 FE and 5 other cards benchmarked with 42 games

Here are the performance results of 42 games and 3 synthetic tests. The highest settings are used and are listed on the charts. The benches were run at 2560×1440 and 3840×2160. Click on each chart to open in a pop-up for best viewing. Gaming results show average framerates in bold text, and higher is better. Minimum framerates are next to the averages in italics and in a slightly smaller font which represent a game’s average 1% lows (99th percentiles).

The first set of charts show the seven main competing cards. Column two represents the $999 Hellhound RX 7900 XTX performance in between the $1599 RTX 4090 FE in column one and the RTX 4080 FE, its $1199 primary competitor, in the third column. The RTX 3080 Ti results are in the fourth column next to Gigabyte RX 6900 XT OC version performance results in the fifth column, followed up by the RTX 3080 in the sixth and the RX 6800 XT in the seventh column.

“Wins” between the RX 7900 XTX and the RTX 4080 are denoted by yellow text. If there is a tie, both values are in yellow.

Playing with the RX 7900 XTX, Elden Ring locked up the PC even after verifying files and reinstalling Adrenaline drivers and it appears a driver issue prevented ray traced Guardians of the Galaxy running on the RX 6800 XT.

The Hellhound RX 7900 XTX and the RTX 4080 and RTX 4090 are cards that are primarily suited for 4K and high-FPS 1440P gaming and they stand out from the other four cards. The RX 7900 XTX trades blows with the RTX 4080 in rasterized games – they are equivalent cards if ray tracing is not considered.

Although RX 7900 XTX ray tracing has greatly improved over the RX 6900 XT and RX 6800 XT, it now appears to perform similarly to the RTX 3080 and RTX 3080 Ti but far behind the RTX 4080. FSR 2.0, although still not on the same image quality level as Nvidia’s DLSS 2, will almost double framerates for a very minor IQ hit and will make most of the games quite playable at Ultra/4K in this 52 game benching suite. Gamers who are not so impressed with ray tracing or who are not picky about image quality perfection may well prefer to save $200 on a $1000 Hellhound RX 7900 XTX over buying a $1200 RTX 4080.

Let’s look at synthetic benches.

Synthetic benches

We hold synthetic benches to be meaningless for predicting real world gaming performance versus competing cards with different architectures although they have other practical uses like overclocking and ranking. The RX 7900 XTX performs better in the synthetic tests than in gaming.

Let’s see how the Hellhound performs in ten popular VR (Virtual Reality) games next.

10 VR Games

For this review, we benchmarked the Valve Index using FCAT VR and set the SteamVR render resolution to 100% (2016×2240) which uses a factor of 1.4X (the native resolution is 1440×1600) to compensate for lens distortion and to increase clarity. We are going to compare the performance of the RX 7900 XTX with the RX 4080 and versus the RX 4090 at each game’s Ultra/Highest settings.

Unfortunately, FCAT VR still doesn’t work with MS Flight Simulator 2020 or with Star Wars Squadrons. Here are the ten VR games we tested.

VR Games

• Assetto Corsa: Competizione
• Elite Dangerous
• F1 2022
• Kayak Mirage
• Moss: Book II
• No Man’s Sky
• Project CARS 2
• Skyrim
• Sniper Elite
• The Walking Dead: Saints & Sinners

Synthetic

• Time Spy & Time Spy Extreme (DX12)
• 3DMark FireStrike – Ultra & Extreme
• Superposition
• VRMark Blue Room

IMPORTANT: BTR’s charts use frametimes in ms where lower is better, but we also compare “unconstrained framerates” which shows what a video card could deliver (headroom) if it wasn’t locked to either 90 FPS or to 45 FPS by the HMD. In the case of unconstrained FPS, measuring just one important performance metric, faster is better.

Let’s individually look at our 10 sim-heavy VR games’ performance using FCAT VR.

First up, Assetto Corsa: Competizione.

Assetto Corsa: Competizione (ACC)

BTR’s sim/racing editor, Sean Kaldahl created the replay benchmark run that we use for both the pancake game and the VR game. It is run at night with 20 cars, lots of geometry, and the lighting effects of the headlights, tail lights, and everything around the track looks spectacular.

Just like with Project CARS, you can save a replay after a race. Fortunately, the CPU usage is the same between a race and its replay so it is a reasonably accurate benchmark using the Circuit de Spa-Francorchamps. iRacing may be more accurate or realistic, but Assetto Corsa: Competizione has some appeal because it feels more real than many other racing sims. It delivers the sensation of handling a highly-tuned racing machine driven to its edge.

Here are the ACC FCAT VR frametimes using VR Ultra using the Hellhound RX 7900 XTX, the RTX 4080 FE, and the RTX 4090 FE.

Here are the details are reported by FCAT-VR:

The RX 7900 XTX managed 85.77 unconstrained FPS with 6339 (50%) synthesized frames with no dropped frames nor Warp misses.

The RTX 4080 delivered 118.42 unconstrained FPS with 207 (2%) synthesized frames with 1 dropped frame and 1 Warp miss.

The RTX 4090 achieved 164.03 unconstrained FPS together with 1 synthetic frame but with no dropped frames nor Warp misses.

The ACC racing experience is best with the RTX 4090 although the RTX 4080 delivers a nearly constant 90 FPS on the Epic VR preset unlike the RX 7900 XTX which requires one-half of its frames to be synthesized.

Next, we check out Elite Dangerous.

Elite Dangerous (ED)

Elite Dangerous is a popular space sim built using the COBRA engine. It is hard to find a repeatable benchmark outside of the training missions.

A player will probably spend a lot of time piloting his space cruiser while completing a multitude of tasks as well as visiting space stations and orbiting a multitude of different planets. Elite Dangerous is also co-op and multiplayer with a dedicated following of players.

We picked the Ultra Preset and we set the Field of View to its maximum.

Here are the frametimes.

Here are the details as reported by FCAT-VR:

The RX 7900 XTX managed 185.21 unconstrained FPS with no synthesized frames with no dropped frames or Warp misses.

The RTX 4080 delivered 230.98 unconstrained FPS with 1 synthesized frame and 1 dropped frame and 1 Warp miss.

The RTX 4090 brings 296.16 unconstrained FPS together with 2 synthetic frames but with 2 dropped frames and 2 Warp misses.

Although the Hellhound RX 7900 XTX has the lowest performance, the experience playing Elite Dangerous at Ultra settings is not perceptibly different on any tested video card. However, the RTX 4090 has a lot more performance headroom to increase the render resolution or to use a higher resolution headset like the Reverb G2 or the Vive Pro 2.

Let’s look at our newest VR sim, F1 2022.

F1 2022

Codemasters has captured the entire Formula 1 2021 season racing in F1 2022, and the VR immersion is good. The graphics are customizeable and solid, handling and physics are good, the AI is acceptable, the scenery is outstanding, and the experience ticks many of the necessary boxes for a racing sim.

Here is the frametime plot for F1 2022.

Here are the details as reported by FCAT-VR.

The RX 7900 XTX delivered 156.57 unconstrained FPS with 6 synthesized but no dropped frames nor Warp misses.

The RTX 4080 achieved 200.24 unconstrained FPS with no synthesized or dropped frames nor Warp misses.

The RTX 4090 delivered 254.72 unconstrained FPS together with 3 synthetic frames plus with 3 dropped frames and 3 Warp misses.

The experience playing F1 2022 using the Ultra preset is not very different on any of these video cards but the RTX 4090 and RTX 4080 have considerably more performance headroom than the RX 7900 XTX to use 120Hz/144Hz or to use a higher resolution headset.

Kayak VR: Mirage

The outstanding near-photorealistic visual fidelity really sets Kayak VR: Mirage apart from other simulators. It boasts a wide range of locales with day/night/sunset options offering tropical, icy, desert, and even stormy scenarios with trips to Costa Rica, Antarctica, Norway, and Australia and occasional interactions with wildlife. It can be played as a relaxing sim or as a strenuous workout with competitive time trials which offer asynchronous multiplayer and ranking on global leaderboards.

We benchmark at 100% resolution with the highest “Cinematic” in-game settings but do not use DLSS or FSR.

Here is the frametime plot for Kayak VR: Mirage.

Here are the FCAT-VR details.

The RX 7900 XTX delivered 198.98 unconstrained FPS with no synthesized frames or dropped frames nor Warp misses.

The RTX 4080 delivered 257.16 unconstrained FPS with 1 synthesized and 1 dropped frame and 1 Warp miss.

The RTX 4090 got 329.35 unconstrained FPS together with 1 synthetic frame and 1 dropped frame plus 1 Warp miss.

Kayak VR: Mirage looks fantastic at 100% resolution with maximum settings and would be well-suited for play on the Reverb G2 with any of our test cards.

Next, we look at Moss: Book II.

Moss: Book II

Moss: Book II is an amazing VR experience with much better graphics than the original game. It’s a 3rd person puzzle adventure game played seated that offers a direct physical interaction between you (the Reader) and your avatar, Quill, a mouse that bring real depth to the story. Extreme attention has been paid to the tiniest details with overall great art composition and outstanding lighting that make this game a must-play for gamers of all ages.

Moss II boasts very good visuals and we use the in-game highest settings.

Here are the frametimes plots of our four cards.

Here are the details are reported by FCAT-VR:

The RX 7900 XTX delivered 189.29 unconstrained FPS with no synthesized or dropped frames nor Warp misses.

The RTX 4080 delivered 308.44 unconstrained FPS with 1 synthetic and 1 dropped frame and 1 Warp miss.

The RTX 4090 achieved 436.34 unconstrained FPS no synthesized or dropped frames nor Warp misses.

Unfortunately, the experience playing Moss II on the Valve Index using the RX 7900 XTX is marred by visual issues including artifacting and shimmering.

Next, we will check out another demanding VR game, No Man’s Sky.

No Man’s Sky (NMS)

No Man’s Sky is an action-adventure survival single and multiplayer game that emphasizes survival, exploration, fighting, and trading. It is set in a procedurally generated deterministic open universe, which includes over 18 quintillion unique planets using its own custom game engine.

The player takes the role of a Traveller in an uncharted universe by starting on a random planet with a damaged spacecraft equipped with only a jetpack-equipped exosuit and a versatile multi-tool that can also be used for defense. The player is encouraged to find resources to repair his spacecraft allowing for intra- and inter-planetary travel, and to interact with other players.

Here is the No Man’s Sky frametime plot. We set the settings to Maximum which is a step over Ultra including setting the anisotropic filtering to 16X and upgrading to FXAA. We did not use any upscaling method.

Here are the FCAT-VR details of our comparative runs.

The RX 7900 XTX brought 108.17 unconstrained FPS with 3536 (50%) synthesized frames but no dropped frames nor Warp misses.

The RTX 4080 delivered 159.10 unconstrained FPS with 2 synthesized frames but with no dropped frames nor Warp misses.

The RTX 4090 achieved 201.96 unconstrained FPS together with 17 synthetic frames but with no dropped frames nor Warp misses.

RX 7900 XTX gamers may want to lower some individual settings to remain above 90 FPS. The RTX 4080 and RTX 4090 have enough performance headroom to increase the refresh rate, render resolution, or to perhaps use a higher resolution headset.

Let’s continue with another VR game, Project CARS 2, that we still like better than its successor even though it is no longer available for online play.

Project CARS 2 (PC2)

There is still a sense of immersion that comes from playing Project CARS 2 in VR using a wheel and pedals. It uses its in-house Madness engine, and the physics implementation is outstanding.

Project CARS 2 offers many performance options and settings.

We used maximum settings including for Motion Blur but picked SMAA Ultra instead of MSAA.

Here is the frametime plot.

Here are the FCAT-VR details.

The RX 7900 XTX delivered 194.77 unconstrained FPS with no synthesized nor dropped frames or Warp misses.

The RTX 4080 got 200.88 unconstrained FPS with no synthesized frames nor dropped frames and no Warp misses.

The RTX 4090 achieved 253.50 unconstrained FPS together with 3 synthetic frames plus 2 dropped frames and 2 Warp misses.

The experience playing Project CARS 2 using maximum settings is similar for all three video cards.

Next we will check out a classic VR game, Skyrim VR.

Skyrim VR

Skyrim VR is an older game that is no longer supported by Bethesda, but fortunately the modding community has adopted it. It is not as demanding as many of the newer VR ports so its performance is still very good on maxed-out settings using its Creation engine.

We benchmarked vanilla Skyrim using its highest settings plus we increased the in-game Supersample option to maximum.

Here are the frametime results.

Here are the details of our comparative runs as reported by FCAT-VR.

The RX 7900 XTX provided 218.2 unconstrained FPS with no synthesized or dropped frames nor Warp misses.

The RTX 4080 achieved 239.08 unconstrained FPS with 2 synthetic frames plus 2 dropped frames and 1 Warp miss.

The RTX 4090 delivered 337.76 unconstrained FPS together with 2 synthetic frame and with 2 dropped frames plus 1 Warp miss.

All cards deliver an identical vanilla Skyrim VR experience with a ton of extra performance headroom to add mods and, in addition, to raise the render resolution using the two faster cards.

Next we check out Sniper Elite VR.

Sniper Elite VR

Sniper Elite VR’s visuals are decent with good texture work that is well-realized. The building architecture and panoramas look good, explosions are convincing and the weapons convey a sense of weight, although not achieving realism. It is primarily an arcade style sniping game featuring its signature X-Ray kill cam, but it offers multiple ways to achieve goals including with explosives and by using three other main weapon choices besides your rifle.

We benchmarked using the Highest settings.

Here is the frametime plot.

Here are the details:

The RX 6900 XT delivered 197.98 unconstrained FPS with no synthesized or dropped frames nor Warp misses.

The RTX 4080 delivered 223.33 unconstrained FPS with no synthesized or dropped frames nor Warp misses.

The RTX 4090 brought 318.03 unconstrained FPS together with 1 synthetic and 1 dropped frames and 1 Warp miss.

All three cards deliver a similar playing experience on High with the RTX cards offering more performance headroom. We recommend that any performance headroom be used for increasing the SteamVR render resolution.

Last up, The Walking Dead: Saints & Sinners.

The Walking Dead: Saints & Sinners

The Walking Dead: Saints & Sinner is the last of BTR’s 10 VR game benching suite. It is a first person survival horror adventure RPG with a strong emphasis on crafting. Its visuals using the Unreal 4 engine are very good and it makes good use of physics for interactions.

We benchmarked Saints and Sinners using its High preset and we left the Pixel Density at 100%. Here is the frametime chart.

Here are the details as reported by FCAT-VR.

The RX 7900 XTX delivered 198.93 unconstrained FPS with no synthetic nor dropped frames or Warp misses.

The RTX 4080 got 260.94 unconstrained FPS with 1 synthetic frames and 1 dropped frames and 1 Warp miss.

The RTX 4090 achieved 366.41 unconstrained FPS together with 6 synthetic frames and with 4 dropped frames and 4 Warp misses.

The RX 7900 XTX experience was marred by artifacting and shimmering.

Let’s check out synthetic VR tests and unconstrained framerates.

Unconstrained Framerates & Synthetic VR Benchmarks

The following chart summarizes the overall Unconstrained Framerates (the performance headroom) of our three cards using our 10 VR test games. In addition, we added recent RTX 3080 Ti and 6900 XT results for comparison. The preset is listed on the chart and higher is better. In addition, we present three synthetic VR benchmarks.

Although synthetic VR benches (except for OpenVR benchmark) predicted good VR performance, we were disappointed with our 7900 XTX VR experience, unlike with pancake games. In at least two games, we experienced distracting visual artifacting and texture shimmering. The 7900 series may benefit from some attention to VR from the Radeon driver team as in many cases it even falls behind the RX 6900 XT.

At AMD’s press event in Las Vegas, the presenters noted that AMD drivers continue to improve for the entire life of the architecture – generally with an up to 10% performance gain – often compared to “fine wine” aging well. However, for VR enthusiasts today, the RX 7900 XTX is disappointing and it performs well behind the RTX 4080 not logging a single performance win.

We next look at creative, pro, GPGPU, and workstation apps.

Creative, Pro & Workstation Apps

Let’s look at non-gaming applications next to see if the RX 7900 XTX is a good upgrade from the other video cards that we tested starting with Blender.

Blender 3.3.0 Benchmark

Blender is a very popular open source 3D content creation suite. It supports every aspect of 3D development with a complete range of tools for professional 3D creation.

We benchmarked three Blender 3.3.0 benchmarks which measure GPU performance by timing how long it takes to render production files. We tested seven of our comparison cards using CUDA, Optix, and OpenCL.

For the following chart, higher is better as the benchmark renders a scene multiple times and gives the results in samples per minute.

The RX 7900 XTX sits well ahead of the RX 6800 XT and 6900 XT but well behind the GeForce cards.

Next, we move on to AIDA64 GPGPU benchmarks.

AIDA64 v6.80

AIDA64 is an important industry tool for benchmarkers. Its GPGPU benchmarks measure performance and give scores to compare against other popular video cards.

AIDA64’s benchmark code methods are written in Assembly language, and they are well-optimized for every popular AMD, Intel, NVIDIA and VIA processor by utilizing the appropriate instruction set extensions. We use the Engineer’s full version of AIDA64 courtesy of FinalWire. AIDA64 is free to to try and use for 30 days. CPU results are also shown for comparison with both the RTX 3070 and GTX 2080 Ti GPGPU benchmarks.

Here are the Hellhound RX 7900 XTX AIDA64 GPGPU results compared with an overclocked i9-13900KF.

Here is the chart summary of the AIDA64 GPGPU benchmarks with seven of our competing cards side-by-side.

The RX 7900 XTX is a fast GPGPU card and it compares favorably with the competing cards being weaker in some areas and stronger in others. So let’s look at Sandra 2020 next.

SiSoft Sandra 2020

To see where the CPU, GPU, and motherboard performance results differ, there is no better tool than SiSoft’s Sandra 2020. SiSoftware SANDRA (the System ANalyser, Diagnostic and Reporting Assistant) is a excellent information & diagnostic utility in a complete package. It is able to provide all the information about your hardware, software, and other devices for diagnosis and for benchmarking.

There are several versions of Sandra, including a free version of Sandra Lite that anyone can download and use. Sandra 2020 R10 is the latest version, and we are using the full engineer suite courtesy of SiSoft. Sandra 2020 features continuous multiple monthly incremental improvements over earlier versions of Sandra. It will benchmark and analyze all of the important PC subsystems and even rank your PC while giving recommendations for improvement.

We ran Sandra’s intensive GPGPU benchmarks and charted the results summarizing them.

In Sandra GPGPU benchmarks, since the architectures are different, each card exhibits different characteristics with different strengths and weaknesses. However, we see some very solid solid improvement of the RX 7900 XTX over the RX 6900 XT and the RX 6800 XT.

SPECworkstation3 (3.0.4) Benchmarks

All the SPECworkstation3 benchmarks are based on professional applications, most of which are in the CAD/CAM or media and entertainment fields. All of these benchmarks are free except for vendors of computer-related products and/or services.

The most comprehensive workstation benchmark is SPECworkstation3. It’s a free-standing benchmark which does not require ancillary software. It measures GPU, CPU, storage and all other major aspects of workstation performance based on actual applications and representative workloads. We only tested the GPU-related workstation performance as checked in the image above.

Here are our SPECworkstation 3.0.4 raw scores for the Hellhound RX 7900 XTX. RTX 4080 raw scores are displayed below the XTX results for a detailed performance comparison.

Here are our RTX 4080 SPECworkstation 3.1 raw scores:

Here are the Hellhound XTX SPECworkstation3 results summarized in a chart along with six competing cards. Higher is better.

Using SPEC benchmarks, since the architectures are different, the cards each exhibit different characteristics with different strengths and weaknesses.

SPECviewperf 2020 GPU Benches

The SPEC Graphics Performance Characterization Group (SPECgpc) has released a new 2020 version of its SPECviewperf benchmark recently that features updated viewsets, new models, support for both 2K and 4K display resolutions, and improved set-up and results management.

We benchmarked at 4K and here are the summary results for the Hellhound RX 7900 XTX.

Here are SPECviewperf 2020 Hellhound RX 7900 XTX benchmarks summarized in a chart together with six other cards.

Again we see different architectures with different strengths and weaknesses. After seeing these benches, some creative users may upgrade their existing systems with a new card based on the performance increases and the associated increases in productivity that they require.

The question to buy a new video card should be based on the workflow and requirements of each user as well as their budget. Time is money depending on how these apps are used. However, the target demographic for the reference and Hellhound RX 7900 XTXs are primarily gaming for gamers.

Let’s head to our conclusion.

The Conclusion

The Hellhound RX 7900 XTX improves significantly over the last generation RX 6900 XT, easily exceeds RX 6800 XT performance, and it trades blows with the $200 more expensive RTX 4080 FE in rasterized games although overall it is slightly slower using our 42-game benching suite. The Hellhound RX 7900 XTX beats all of the last generation cards including the RTX 3080 Ti although it still struggles with ray traced games compared with RTX cards.

For Radeon gamers, the Hellhound RX 7900 XTX is a good alternative to GeForce Ada Lovelace cards for the vast majority of modern PC games that use rasterization. The RX 7900 XTX offers 24GB of GDDR6 to the 16GB of GDDR6X that the RTX 4080s are equipped with, but that 8GB of vRAM shouldn’t make any practical difference to game performance in the near future.

At its suggested price of $999, the Hellhound RX 7900 XTX costs about $200 less than the RTX 4080 FE and offers a good value for Radeon gamers. Unlike with the RTX 4080 which increased from $700 for the RTX 3080 to $1200, the RX 7900 XTX is priced the same $999 as AMD’s last generation RX 6900 XT. For Radeon buyers, what makes the Hellhound XTX particularly attractive is that there is no price premium for this mildly overclocked PowerColor card.

The only real issue that we see with Radeon 7000 series cards is that AMD’s FSR solution is still inferior to Nvidia’s DLSS AI upscaling that delivers similar performance but with better image quality. On the flip side, there are still relatively few ray traced games released every year in comparison to thousands of rasterized games where the RTX 7900 XTX trades blows with the much more expensive RTX 4080.

One major issue although affecting relatively few gamers is poor VR RX 7900 XTX performance compared with the RTX 4080. It’s going to need some attention from AMD’s driver team before we can recommend the RX 7900 XTX for the best VR gaming.

We recommend the Hellhound RX 7900 XTX as a great choice out of multiple good choices, especially for any AMD PC gamer looking for good looks with LED lighting, an exceptional cooler, great performance for 2560×1440 or 4K, PowerColor’s excellent support, and overall better value compared with the slower RX 7900 XTX reference version.

Let’s sum it up:

Hellhound RX 7900 XTX Pros

• The PowerColor Hellhound RX 7900 XTX is much faster than the last generation RX 6900 XT by virtue of new RDNA 3 architecture. It trades blows in the majority of rasterized games with the RTX 4080 FE for significantly less money ($200 less)
• The Hellhound RX 7900 XTX has excellent cooling with very little noise and has a very good power delivery and a 3-fan custom cooling design that is very quiet when overclocked even using the OC mode
• Dual-BIOS give the user a choice of quiet with less overclocking, or a bit louder with more power-unlimited and higher overclocks
• FidelityFX 2.0 allows for upscaling and improved sharpness with almost no performance penalty, and there is a low latency mode for competitive gamers
• LED lighting and a neutral color allow the Hellhound RX 7900 XTX to fit into any color scheme
• 24GB vRAM compared with 16GB for the RTX 4080

Hellhound XTX Cons

• Cost. It’s still very expensive at $999
• VR performance is subpar
• Weaker ray tracing performance than the RTX 4080

The Hellhound RX 7900 XTX is a good Radeon card choice for those who game at 2560×1440 or at 4K and want the best that AMD has to offer. It represents a good gaming alternative to the RTX 4080 albeit with weaker ray tracing performance. It is offered especially for those who prefer AMD cards and FreeSync2 enabled displays which are generally less expensive than Gsync displays. And if a gamer is looking for something extra above the reference version, the PowerColor Hellhound RX 7900 XTX is a very well-made and good-looking card that will overclock better.

We are giving the Hellhound RX 7900 XTX BTR’s Recommended Award.

The Verdict:

• PowerColor’s Hellhound RX 7900 XTX is a solidly-built handsome card with higher clocks out of the box than the same-priced reference version. It trades blows with the RTX 4080 in rasterized games. I t is a kick ass RX 7900 XTX.

Stay tuned, there is much more coming from BTR. We will soon return to VR with a mega performance evaluation to test the role of the CPU for VR performance. And we’ll retest the RX 7900 XTX using higher resolution headsets after AMD’s driver team has a chance to address it’s VR issues. We also plan to test Intel ARC video cards in VR.

Happy Gaming!

The Red Devil RX 6600 XT arrived at BTR for evaluation from PowerColor as a premium and overclocked 8GB vRAM-equipped 128-bit card with no manufacturer recommended (SEP/MSRP) pricing as yet although the base models start at a rather high $379 considering it is targeting 1080P. We have been exhaustively comparing it versus the $329 RTX 3060 EVGA Black 12GB and versus the $399 RTX 3060 Ti 8GB Founders Edition using 32 games, GPGPU, workstation, SPEC, and synthetic benchmarks.

We will also compare the performance of these competing cards with the RX 6600 XT’s bigger brother, the Red Devil RX 6700 XT (the reference card SEP is $479), and also with its predecessor the ASUS TUF Gaming X3 RX 5600 XT (at $309 which is $30 above AMD’s entry-level pricing of $279); and also with the RX 5700 XT Anniversary Edition ($499/$449 reference at launch).

The Red Devil RX 6600 XT is factory clocked higher than the reference specifications using its OC BIOS. While the reference Radeon RX 6600 XT offers a Game clock up to 2359MHz and a Boost clock of 2589MHz, the PowerColor Red Devil game clocks up to 2428MHz and boosts to 2607MHz. It also looks different from older generation classic Red Devils, arriving in a more neutral gray color instead of in all red and black. The Red Devil RX 6600 XT features a RGB mode whose LEDs default to a bright red which may be customized by PowerColor’s DevilZone software.

The Reference and Red Devil RX 6600 XT Features & Specifications

First let’s look at the Red Devil RX 6600 XT specifications:

Additional Information from PowerColor

PowerColor newest 6600 XT Red Devil card, is positioned to compete directly with the custom 3060 premium models.

• The card has 2 modes, OC and Silent. 145W / 135W Power target. There’s a bios switch on the side of the card. We designed this card to be very quiet, even on performance mode is considerably quieter most silent cards, but we also advise to try the silent mode as it’s truly whisper quiet, with a normal case with a optimal airflow, you most likely see the card run around 1000 Rpms under this mode.
• The board has 10 Phase VS the 6+2 Phase VRM design on the standard designs meaning is over spec’d in order to deliver the best
  stability and overclock headroom by having such VRM it will run cooler and last longer.
• DrMos and high-polymer Caps are used on our Design, no compromises.
• DUAL FAN, at this TDP there is no need of oversized 3 fan coolers, better sized and yet efficient cooling!
• Our cooler features 2 x 100mm ,all with two ball bearing fans with 4 heat pipes (4X6Φ) across the high density heatsink with large nickel plated base.
• RGB is enhanced, Red Devil now connects to the motherboard aRGB (5v 3 pin connector) for RGB Sync.
• Red Devil has Mute fan technology, fans stop under 60c!
• The ports are LED illuminated. Now you can see in the dark where to plug.
• The card back plate does not have thermal pads but instead we did cuts across the backplate for the PCB to breath, which under high
  heat scenarios is more beneficial than having thermal pads as the back plate can become a heat trap.
• Red Devil buyers will be able to join exclusive giveaway as well access to the Devil Club website. A membership club for Devil users only which gives them access to News, Competitions, Downloads and most important instant support via Live chat.

RX 6000 features

AMD has their own ecosystem for gamers and many unique new features for the Radeon 6000 series. However, the above slide from AMD does not mention two features – the Infinity Cache and Smart Access Memory.

Infinity Cache & Smart Access Memory

AMD’s RDNA 2 architecture includes the Infinity Cache which alters the way data is delivered to GPUs. This global cache allows fast data
access and increases bandwidth. This optimized on-die cache uses 96MB of AMD Infinity Cache delivering up to 2.5x the effective bandwidth compared to 256-bit 12Gbps GDDR6.

BTR uses Intel’s 10th generation flagship CPU, the i9-10990K which does not have this cache available so our results will probably be lower than what a gamer using a full Ryzen 5000 platform will achieve. In addition, we don’t have Smart Access Memory.

AMD’s Smart Access Memory is a new feature for the Radeon RX 6000 Series graphics cards that enables additional memory space to be mapped to the base address register resulting in performance gains for select games when paired with an AMD Ryzen 5000 Series processor or with some Ryzen 3000 series CPUs. Using PCIe, the Base Address Register (BAR) defines how much GPU memory space can be mapped. Without using Smart Access Memory, CPUs can generally access up to 256MB of GPU memory restricting performance somewhat.

NVIDIA has worked with its partners and with Intel to enable Resizable BAR which currently is enabled for the EVGA Z490 FTW motherboard but it only works for GeForce cards. When we tried to enable it for the RX 6600 XT, our PC refused to boot after following AMD’s instructions using a clean installation of Windows. So we disabled it and tested all of our video cards and games without Resizable BAR.

The Test Bed

BTR’s test bed consists of 32 games and 3 synthetic game benchmarks at 1920×1080 and 2560×1440, as well as SPEC, workstation, and GPGPU benchmarks. Our latest games include Chernobylite and F1 2021. The testing platform uses a recent installation of Windows 10 64-bit Pro Edition, and our CPU is an i9-10900K which turbos all 10 cores to 5.1/5.0GHz, an EVGA Z490 FTW motherboard, and 32GB of T-FORCE Dark Z DDR4 at 3600MHz. The games, settings, and hardware are identical except for the cards being compared.

First, let’s take a closer look at the new PowerColor Red Devil RX 6600 XT.

A Closer Look at the Red Devil RX 6600 XT

Although the Red Devil RX 6600 XT advertises itself as a premium 7nm 8GB vRAM-equipped card on AMD’s RDNA 2 architecture which features 1080P and PCIe 4.0, the cover of the box favors stylized imagery over text.

The back of the box touts key features which now include HDMI 2.1 VRR, ray tracing technology, FidelityFX, and VR Ready Premium as well as states its 600W power and system requirements. AMD’s technology features are highlighted and the box features PowerColor’s custom cooling solution, Dual-BIOSes, RGB software and output LEDs, and a solid backplate with the Red Devil logo that also lights up.

Opening its very well-padded box, we see a quick installation guide, a RGB LED cable, and an invitation to join PowerColor’s Devil’s Club.

The Red Devil RX 6600 XT is a dual-fan card. Turning the Red Devil over (below) we see a solid backplate that features the devil logo that also lights up.

The Red Devil RX 6600 XT is a medium-sized dual-fan card (251mm long x 133mm tall x 54mm thick) in a 2 slot design which is quite handsome with PowerColor’s colors and even more striking with the RGB on.There is also a switch to choose between the default overclock (OC) BIOS and the Silent BIOS (above, right). Using the OC BIOS the card has a 145W power target and using the Silent BIOS it has a 135W power target. We didn’t bother with the Silent BIOS as the card is very quiet using the OC BIOS, but it is good to have in case a flash goes bad.

The Red Devil uses one 1×8-pin and 1×6-pin PCIe connections while the reference version uses 1×8-pin. We would suggest that with the current voltage limitations and low power draw, the extra connector is probably not really necessary even for overclocking unless the end user circumvents the power restrictions using MPT at their own risk. Looking at the edges, we can see it is all heatsink fins for cooling as is typical of Red Devil cards, and we expect it to run cool.

Above, the PowerColor Red Devil RX 6600 XT’s other end also lights up giving the card an aggressive look.

The Red Devil’s RX 6600 XT’s connectors include 3 DisplayPorts and 1 HDMI connector. There is an LED that illuminates this panel for making easier connections in the dark.

The Red Devil looks great when it is running in a PC.

The specifications look good and the Red Devil itself looks great with its default RGB bright red contrasting with the black backplate and its aggressively lit-up front end perhaps is stylistically reminiscent of an automotive grill or perhaps teeth. The end user may enhance and coordinate the RGB colors by connecting to the motherboard using a supplied aRGB (5v 3-pin) connector using the DevilZone RGB software.

Let’s check out its performance after we look over our test configuration and more on the next page.

NVIDIA Control Panel settings

Here are the NVIDIA Control Panel settings.

Next the AMD settings.

AMD Adrenalin Control Center Settings

All AMD settings are set so that all optimizations are off, Vsync is forced off, Texture filtering is set to High, and Tessellation uses application settings. All Navi cards are capable of high Tessellation unlike earlier generations of Radeons.

Anisotropic Filtering is disabled by default but we always use 16X for all game benchmarks.

Let’s check out overclocking, temperatures and noise next.

Overclocking, temperatures and noise

We spent a lot of time overclocking the Red Devil RX 6600 XT for this review. The Red Devil is factory clocked higher than the reference specifications using its OC BIOS. While the reference Radeon RX 6600 XT offers a Game clock up to 2359MHz and a Boost clock of 2589MHz, the PowerColor Red Devil game clocks up to 2428MHz and boosts to 2607MHz.

Above are the reference RX 6600 XT Wattman default settings which include leaving the power limit at default. The performance didn’t matter whether the power limit was set to default or higher even when overclocked. Although the Red Devil boosts to 2607MHz, we typically saw clocks at around 2575MHz and the GPU stayed cool. The fan speeds are not tracked by Wattman but they remained low and we could not hear them over our other case fans.

The Wattman auto overclock feature is useless as it gave an extremely low overclock so we used trial and error to find Red Devil’s maximum performance at the edge of stability. We settled on increasing the memory to 115% (2284MHz) and increasing the core clock by 7% (2776MHz) as below.

At maximum overclock, the clocks run from 2686MHz to a peak of 2720MHz, but this time the temperatures drop below 60C as the fan speeds increase. Even while overclocked to the max, the Red Devil remains very quiet and cool with power consumption just approaching 140W.

There is a small performance increase from overclocking the RX 6600 XT core by 7% and increasing the memory by 15%. Unfortunately, AMD has again locked all RX 6600 XT cards overclocking down in an attempt to maximize overall performance by limiting the voltage to 1150mV. We would also suggest that the RX 6600 XT is rather voltage constrained and the Red Devil could seriously benefit by more voltage. We suspect that some enthusiast gamers will use MPT (More Power Tool) and risk their warranty to gain a substantially higher Red Devil overclock although we cannot recommend it.

We believe that the Red Devil’s overclock will not degrade over time as its PCB components are fit to run all the time at the highest overclock settings – perhaps unlike entry level versions which are not engineered for ultimate maximum reliability.

Of course, many gamers will want to fine-tune their own overclock and undervolting is a possibility although at 140W the Red Devil RX 6600 XT is not a power hog. Check the overclocking chart in the next section for performance increases using ten key games.

Let’s head to the performance charts to see how the performance of the RX 6600 XT compares with five other cards.

Performance summary charts

Here are the performance results of 32 games and 3 synthetic tests comparing the factory-clocked 8GB Red Devil RX 6600 XT with the EVGA RTX 3060 Black 12GB (reference) and versus the RTX 3060 Ti FE 8GB at their factory set clocks. Three other cards are added for comparison in the Big Picture. The highest settings are used and are listed on the charts. The benches were run at 1920×1080 and at 2560×1440. Click on each chart to open in a pop-up for best viewing.

Most gaming results show average framerates in bold text, and higher is better. Minimum framerates are next to the averages in italics and in a slightly smaller font. The games benched with OCAT show average framerates but the minimums are expressed by frametimes in ms where lower numbers are better.

The Red Devil RX 6600 XT vs. the RTX 3060 & RTX 3060 Ti

The first set of charts show our three main competing cards. Column one represents the RTX 3060 EVGA Black (reference speed) version ($329) performance, column two is the Red Devil RX 6600 XT (no SEP/reference $379), and column three represents the RTX 3060 Ti FE ($399) performance.

The Red Devil RX 6600 XT is faster overall than the RTX 3060 EVGA Black (reference) version but it is still in the same class, trading blows depending on the games tested. Since we do not use Resizable BAR or have Smart Access Memory, we expect that some games would shift in favor of the Radeon using a Ryzen 5000 platform. However, it is outclassed by the $20 more expensive RTX 3060 Ti, winning no games against it.

Let’s see how the reference and Red Devil RX 6600 XT fit in with our expanded main summary chart, the “Big Picture”, comparing a total of six cards.

The Big Picture

Here is how the Red Devil 6600 XT fits into a larger chart with six cards. The ASUS RX 5600 XT is in column one, the RX 5700 XT (Anniversary Edition) is in column 2, the EVGA Black RTX 3060 is in column 3, the Red Devil RX 6600 XT is in Column 4, the RTX 3060 Ti FE is in column 5, and the Red Devil RX 6700 XT is in column 6.

We see that the RX 6600 XT is a fair upgrade from the RX 5600 XT, but it is hard to believe that AMD has increased the price by $100 over the last midrange 1080P generation. The RX 6600 XT basically trades blows with the RX 5700 XT which launched at $399. We have to wonder what AMD was thinking when they set their pricing so high.

Ray Traced Benchmarks

The Red Devil RX 6600 XT is next compared with our other two main competing cards when ray tracing is enabled in ten games. No DLSS or FSR technologies are used.

The RX 6600 XT gets outperformed overall when compared with the $50 less expensive RTX 3060 after ray tracing is enabled. However, AMD has recently introduced FidelityFX Super Resolution (FSR) which is their answer to NVIDIA’s DLSS.

FidelityFX Super Resolution (FSR)

FSR improves performance by first rendering frames at a lower resolution and then by using an open-source spatial upscaling algorithm with a sharpening filter in an attempt to make the game look nearly as good as at native resolution. NVIDIA’s DLSS is a more mature temporal upscaling solution that uses AI/Deep Learning. With DLSS, data is accumulated from multiple frames and combined into the final image with the AI reconstruction component running on GeForce RTX Tensor cores.

In contrast, FSR is basically a post-process shader which also makes it easy for game developers to implement across all graphics cards and not just for Radeons. So far, there are about a dozen games that use it and we have tested three games that use FSR. Although Ultra FSR is not the equal of DLSS – and especially not of DLSS 2.0 Quality which rivals and sometimes improves on the native image – it is still a very solid non-AI/temporal upscaler that provides good performance improvements.

Ultra FSR is far more than a standard Lanczos implementation plus sharpening and it brings good value to Radeons (and for all video cards!) for higher “free” performance with a minimal hit to visuals. We were especially impressed with the Ultra FSR implementation in Chernobylite. Below is a performance comparison of Quality DLSS 2.0 versus Ultra FSR.

We see the RX 6600 XT improve its framerates using Ultra FSR to match the RTX 3060 which uses Quality DLSS in Chernobylite.

Again, we see solid performance improvements with Godfall and in Resident Evil Village using Ultra FSR.

Next we look at overclocked performance.

Overclocked benchmarks

These ten benchmarks were run with both Red Devil RX 6600 XT overclocked as far as it can go while remaining stable as described in the overclocking section. The Red Devil manually overclocked card results are presented first and the factory-clocked results are in the second column.

There is a reasonable performance increase from manually overclocking the Red Devil RX 6600 XT beyond its factory clocks from about 2% up to around 10%.

Let’s look at non-gaming applications next to see if the RX 6600 XT is a good upgrade from the other video cards we test starting with Blender.

Blender 2.931 Benchmark

Blender is a very popular open source 3D content creation suite. It supports every aspect of 3D development with a complete range of tools for professional 3D creation.

We benchmarked three Blender benchmarks which measure GPU performance by timing how long it takes to render production files. We tested our comparison cards using OpenCL for the Radeons and CUDA on GeForce – all running on the GPU instead of using the CPU.

For the following chart, lower is better as the benchmark renders a scene multiple times and gives the results in minutes and seconds.

OpenCL is not as well-optimized for Radeons compared with CUDA for GeForce.

Next, we move on to AIDA64 GPGPU benchmarks.

AIDA64 v6.32

AIDA64 is an important industry tool for benchmarkers. Its GPGPU benchmarks measure performance and give scores to compare against other popular video cards.

AIDA64’s benchmark code methods are written in Assembly language, and they are well-optimized for every popular AMD, Intel, NVIDIA and VIA processor by utilizing the appropriate instruction set extensions. We use the Engineer’s full version of AIDA64 courtesy of FinalWire. AIDA64 is free to to try and use for 30 days. CPU results are also shown for comparison.

Here are the Red Devil RX 6600 XT AIDA64 GPGPU results compared with an overclocked i9-10900K.

Here is the chart summary of the AIDA64 GPGPU benchmarks with five of our competing cards side-by-side.

The RX 6600 XT is a fast GPGPU card and it compares favorably with Ampere cards, being weaker in some areas and stronger in others, and it’s a solid improvement over the last generation RX 5600 XT. So let’s look at Sandra 2020 next.

SiSoft Sandra 2020

To see where the CPU, GPU, and motherboard performance results differ, there is no better tool than SiSoft’s Sandra 2020. SiSoftware SANDRA (the System ANalyser, Diagnostic and Reporting Assistant) is a excellent information & diagnostic utility in a complete package. It is able to provide all the information about your hardware, software, and other devices for diagnosis and for benchmarking. Sandra is derived from a Greek name that implies “defender” or “helper”.

There are several versions of Sandra, including a free version of Sandra Lite that anyone can download and use. Sandra 2021 is the latest version, and we are using the full engineer suite courtesy of SiSoft. Sandra 2020 features continuous multiple monthly incremental improvements over earlier versions of Sandra. It will benchmark and analyze all of the important PC subsystems and even rank your PC while giving recommendations for improvement.

We ran Sandra’s intensive GPGPU benchmarks and charted the results summarizing them.

In Sandra GPGPU benchmarks, since the architectures are different, each card exhibits different characteristics with different strengths and weaknesses. However, we see solid improvements of the RX 6600 XT over the RX 5600 XT.

SPECworkstation3 (3.0.4) Benchmarks

All the SPECworkstation3 benchmarks are based on professional applications, most of which are in the CAD/CAM or media and entertainment fields. All of these benchmarks are free except for vendors of computer-related products and/or services.

The most comprehensive workstation benchmark is SPECworkstation3. It’s a free-standing benchmark which does not require ancillary software. It measures GPU, CPU, storage and all other major aspects of workstation performance based on actual applications and representative workloads. We only tested the GPU-related workstation performance as checked in the image above.

Here are our raw SPECworkstation 3.0.4.summary and raw scores for the Red Devil RX 6600XT that were tested at 1900×1060.

Here are the Red Devil SPECworkstation3 results summarized and included in a chart of our five competing cards. Higher is better.

Using SPEC benchmarks, since the architectures are different, the cards each exhibit different characteristics with different strengths and weaknesses.

SPECviewperf 2020 GPU Benches

The SPEC Graphics Performance Characterization Group (SPECgpc) has released a 2020 version of its SPECviewperf benchmark last year that features updated viewsets, new models, support for both 2K and 4K display resolutions, and improved set-up and results management. We use 2K display resolution for midrange cards like the RX 6600 XT.

Here are the summary results for the Red Devil RX 6600 XT.

Here are SPECviewperf 2020 GPU Red Devil RX 6600 XT benchmarks summarized in a chart together with four other cards.

Again we see different architectures with different strengths and weaknesses. The Red Devil RX 6600 XT is significantly faster than the RX 5600 XT.

After seeing these benches, some creative users may upgrade their existing systems with a new card based on the performance increases and the associated increases in productivity that they require. The question to buy a new video card should be based on the workflow and requirements of each user as well as their budget. Time is money depending on how these apps are used. However, the target demographic for the Red Devil RX 6600 XT is primarily 1080P gaming for gamers.

Let’s head to our conclusion.

Final Thoughts

The Red Devil RX 6600 XT improves significantly over the RX 5600 XT and it trades blows with and overall it beats the RTX 3060 in multiple rasterized games. The Red Devil RX 6600 XT beats the last generation cards including the RX 5600 XT although it struggles with ray traced games compared with GeForce cards. We somewhat handicapped the RX 6600 XT by not being able to use Infinity Cache & Smart Access Memory and we expect that performance would be higher if we used a Ryzen 5000 platform.

FSR brings a great value to the RX 6600 XT as an alternative to DLSS, although it cannot quite match it in visual quality. We look forward to further improvements in FSR and hope many more games use it.

For Radeon gamers, the Red Devil RX 6600 XT is a good alternative to the RTX 3060 for the vast majority of modern PC games that use rasterization. However, the RX 6600 XT offers 8GB of GDDR6 to the 12GB of GDDR6 that the RTX 3060 is equipped with. The RTX 3060, although it has 12GB of vRAM, appears to be wasted for that card.

At its suggested price of $379, or $20 less than the RTX 3060 Ti, the reference RX 6600 XT offers much less value – if the GeForce can be found at all at SEP. PowerColor has promised that the supply of the RX 6600 XT will be plentiful, but we are skeptical. This same thing has been promised for Ampere cards where the stock is still trickling in and being purchased the instant it’s available from etailers that are not hesitating to mark the prices up to double the SEP.

We think that AMD has set pricing too high on the RX 6600 XT by about $50. If it sold for $329 like the RTX 3060, it would be a really good value. They seem to forget that the competing GeForce is much stronger in ray traced games – with over 60 games featuring DLSS – and that FSR is brand new with only a dozen games supporting it so far. At $100 more than what the RX 5600 XT launched at, AMD has jacked up the price of 1080P gaming – pandemic shortages or no shortages – and it is not a consumer friendly move. However, for practical terms – if the RX 6600 XT can be found at MSRP/SEP – it is a good value for now as most other competing cards are still selling for double MSRP.

PowerColor hasn’t set any pricing on the Red Devil RX 6600 XT allowing the resellers to set theirs. They claim that their margins are actually below their usual historical low double-digit (10-12%) for a new product. Unfortunately, it’s hard to recommend any card with no suggested price even though it is overclocked, very nicely equipped, and well-built over a well-designed reference version for $379. We wish that we could say that “PowerColor thinks their Red Devil is worth $30 more than the reference version” – and we would agree. But now there is no pricing frame of reference.

We recommend the Red Devil RX 6600 XT as a great choice out of multiple good choices, especially if you are looking for good looks with RGB, an exceptional cooler, and great performance for 1920×1080, PowerColor’s excellent support, and overall good value assuming that the stock and price stabilizes. We are convinced that PowerColor is an outstanding AMD AIB, and we never hesitate to recommend it to our friends. When we have a choice, we pick and have picked PowerColor video cards for our own purchases.

Let’s sum it up:

The Red Devil RX 6600 XT Pros

• The PowerColor Red Devil RX 6600 XT is much faster than the last generation RX 5600 XT by virtue of new RDNA 2 architecture. It beats the RTX 3060 in many raster games and is a great ultra 1080P card that can handle 1440P with lower settings.
• FSR is an awesome added value that can greatly improves performance without impacting visuals significantly.
• The Red Devil RX 6600 XT has excellent cooling and it is a very quiet card even when overclocked to its maximum
• The Red Devil has a very good power delivery system and dual-fan custom cooling design
• Dual-BIOS give the user a choice of quiet with less overclocking, or a bit louder with more power-unlimited and higher overclocks. It’s also a great safety feature if a BIOS flash goes bad
• FreeSync2 HDR eliminates tearing and stuttering
• Infinity Cache & Smart Access Memory give higher performance with Ryzen 5000 platform
• Customizable RGB lighting and a neutral color allow the Red Devil to fit into any color scheme using the DevilZone software program.

Red Devil RX 6600 XT Cons

• Pricing. $379 for a midrange 1080P card is $100 more than AMD’s RX 5600 XT. And PowerColor has set no SEP
• Weaker ray tracing performance than the RTX 3060

If they can be found at suggested pricing, the Red Devil RX 6600 XT is a good card choice for those who game at 1920×1080, and it represents a good alternative to the RTX 3060 albeit with weaker ray tracing performance. They are offered especially for those who prefer AMD cards and FreeSync2 enabled displays which are generally less expensive than Gsync displays; and Infinity Cache & Smart Access Memory are a real plus for gamers using the Ryzen 5000 platform.

If a gamer is looking for something extra beyond the reference version, the Red Devil RX 6600 XT is a very well made and handsome RGB customizable card that will overclock decently and last a long time without performance degradation.

The Verdict:

• PowerColor’s Red Devil RX 6600 XT is a solidly-built good-looking RGB card with higher clocks out of the box than the reference version and it overclocks decently. It trades blows with and overall beats the RTX 3060 in many rasterized games. Although we have no price, it is a kick-ass RX 6600 XT. Hopefully there will be some solid supply and the market pricing will normalize after the cryptocurrency pandemic ends (relatively soon!).

The Red Devil RX 6600 XT offers a good alternative to the RTX 3060 for solid raster performance in gaming, and it also beats the performance of AMD’s last generation by a good margin. However, everything will depend on pricing and availability.

This is what PowerColor boldly stated to us last week:

“There will be plenty of cards in the channel and we will have our base model Fighting that starts at 379$ at launch!

No Scalping prices, eTailers will have enough cards, if they raise the prices, someone else will sell for less.”

Good advice! We hope there is good availability, and if so, we can recommend the Red Devil RX 6600 XT even if it is sold even at AMD’s inflated SEP pricing because the competing cards are mostly unavailable for even double their MSRP. Do not reward scalpers or etailers who sell at inflated prices and who do not deserve our business. We can outwait them.

Stay tuned, there is much more coming from BTR. This weekend we will return to VR with a performance evaluation comparing the Red Devil RX 6600 XT with the RTX 3060. And stay tuned for Rodrigo’s upcoming 471.68 driver performance analysis!

Happy Gaming!

The Red Devil RX 6700 XT arrived at BTR for evaluation from PowerColor as a 12GB vRAM-equipped card last week with no manufacturer recommended (SEP/MSRP) pricing. We have been comparing it with the just released $479 RX 6700 XT reference card from AMD, and also versus the GeForce $499 RTX 3070 Founders Edition (FE) and the $399 RTX 3060 Ti (FE) using 35 games, GPGPU, workstation, SPEC, and synthetic benchmarks.

We will also compare the performance of these competing cards with the RX 6700 XT’s bigger brother, the RX 6800; with its predecessor the RX 5700 XT Anniversary Edition (AE); and also with the $329 RTX 3060; but especially versus the RTX 2060 and the GTX 1060/6GB to see how older cards fare to complete BTR’s 9-card Big Picture.

The Red Devil RX 6700 XT is factory clocked higher than the reference version (below) using its OC BIOS.

According to its specifications, the Red Devil RX 6700 XT can boost up to 2622MHz out of the box or 41MHz higher than the reference RX 6700 XT which clocks to 2581MHz. It also looks different from older generation classic Red Devils, arriving in a more neutral gray color instead of in all red and black. The Red Devil RX 6700 XT features a RGB mode whose LEDs default to a bright red which may be customized by PowerColor’s DevilZone software.

The Reference and Red Devil RX 6700 XT Features & Specifications

First let’s look at the reference RX 6700 XT specifications compared with its predecessor, the RX 5700 XT

From what we can see from the specifications, the new card should be solidly faster than its predecessor.

Here are the Red Devil RX 6700 XT specifications according to PowerColor:

Specifications

Features

Here are the Red Devil RX 6700 XT features.

Additional Information from PowerColor

• The card has 2 modes, OC and Silent 203W / 186W Power target. There’s a bios switch on the side of the card. We designed this card to be very quiet, even on performance mode is considerably quieter than reference board but we also advise to try the silent mode as it’s truly whisper quiet, with a normal case with a optimal airflow, you most likely see the card run around 1000 Rpms under this mode.
• The board has 12 Phases (10+2 Dr.Mos) VS the 9 (7+2) Phase VRM design on the reference design meaning is over spec’d in order to
  deliver the best stability and overclock headroom, not only capable of well over 250w but by having such VRM it will run cooler and last longer.
• DrMos and high-polymer Caps are used on our Design, no compromises.
• Our cooler features 2 x 100mm with a center 1x90mm fan, all with two ball bearing fans with 6 heat pipes 6Φ across the high density heatsink with coper base. As you might notice the PCB is shorter than the cooler, this design is a continuation of what we already implemented in many generations previously and just now has become almost a industry standard.
• RGB is enhanced, Red Devil now connects to the motherboard aRGB (5v 3 pin connector).
• Red Devil has Mute fan technology, fans stop under 60c!
• The ports are LED illuminated. Now you can see in the dark where to plug.
• The card back plate does not have thermal pads but instead we did cuts across the backplate for the PCB to breath, which under high heat scenarios is more beneficial than having thermal pads as the back plate can become a heat trap.
• Copper Base Direct Touch – A smooth copper base with direct contact to the GPU and VRAMs provides for optimized heat transfer and dissipation
• Buyers or Red Devil Limited edition will be able to join exclusive giveaway as well access to the Devil Club website. A membership club for Devil users only which gives them access to News, Competitions, Downloads, and most important, instant support via Live chat.

The Big Navi 2 Radeon 6000 family

The reference Radeon 6700 XT at $479 competes with the RTX 3070 FE ($499) and is priced $20 lower, but it sits $80 higher than the RTX 3060 Ti ($399). This should tell us that it is expected to trade blows with the RTX 3070, but be solidly faster then the RTX 3060 Ti.

The RX 6800 at $579 competes below the RX 3080 at $699 while the RX 6900 XT at $999 is AMD’s flagship and sits below the $1499 RX 3090. Of course, as PowerColor would have us understand, none of these “suggested” prices have any meaning to gamers currently because of the supply issues and extreme demand caused by the dual pandemics – COVID 19 and cryptocurrency mining.

Above is a die shot of the GPU powering the Radeon RX 6700 XT courtesy of AMD.

AMD has their own ecosystem for gamers and many unique new features for the Radeon 6000 series. However, the above slide from AMD does not mention two very important features – the Infinity Cache and Smart Access Memory.

Infinity Cache & Smart Access Memory

AMD’s RDNA 2 architecture includes the Infinity Cache which alters the way data is delivered to GPUs. This global cache allows fast data
access and increases bandwidth with higher performance and better power efficiency. This highly optimized on-die cache uses 96MB of AMD Infinity Cache delivering up to 2.5x the effective bandwidth compared to 256-bit 12Gbps GDDR6.

Unfortunately, BTR uses Intel’s latest 10th generation flagship CPU, the i9-10990K which does not have this cache available so our results will probably be lower than what a gamer using the Ryzen 5000 platform will see. In addition, we don’t have Smart Access Memory.

AMD’s Smart Access Memory is a new feature for the Radeon RX 6000 Series graphics cards that enables additional memory space to be mapped to the base address register resulting in performance gains for select games when paired with an AMD Ryzen 5000 Series processor or with some Ryzen 3000 series CPUs. Using PCIe, the Base Address Register (BAR) defines how much GPU memory space can be mapped. Until now, CPUs can only access a fraction of GPU memory, often limited to 256MB. With less efficient data transfer, performance is restricted.

NVIDIA has worked with its partners and with Intel to enable Resizable BAR which currently is enabled on the EVGA Z490 FTW motherboard but only works with selected games and with the RTX 3060 for now. When we tried to enable it for the RX 6700 XT, our PC refused to boot. So we had to disable it and test all of our video cards and games without Resizable BAR limiting the RX 6700 XT’s performance.

Last Friday, AMD explained that we would have to do a clean installation of Windows 10 if we wanted to use it, but we simply had no time. Here are their instructions for enabling Resizable BAR for our Intel Z490 motherboard that we shall follow for our future reviews:

If you would like to enable Resizable BAR, we recommend re-installing Windows 10 with these steps:

• Open the BOOT menu and select CSM (Compatibility Support Module)
• Set this value to DISABLED
• Open the ADVANCED menu and choose PCI Configuration
• Set Above 4G Decoding to Enabled
• Set Re-Size BAR Support to Enabled
• Save your changes and install Windows 10

So our performance results may be lower for selected games that can take full advantage of Resizable BAR or Smart Access Memory. Hopefully we will upgrade to a Ryzen 5950X when they become available at a reasonable price and we will retire our i9-10900K. We already are very unhappy with being limited to PCIe Generation 3 using fast SSDs just because Intel chose to hold back the feature until their upcoming 11th generation.

The Test Bed

BTR’s test bed consists of 35 games and 3 synthetic game benchmarks at 1920×1080 and 2560×1440, as well as SPEC, Workstation, and GPGPU benchmarks. Our latest games include Hitman 3, Cyberpunk 2077, DiRT 5, and Godfall. The testing platform uses a recent installation of Windows 10 64-bit Pro Edition, and our CPU is an i9-10900K which turbos all 10 cores to 5.1/5.0GHz, an EVGA Z490 FTW motherboard, and 32GB of T-FORCE Dark Z DDR4 at 3600MHz. The games, settings, and hardware are identical except for the cards being compared.

First, let’s take a closer look at the new PowerColor Red Devil RX 6700 XT which we shall compare with the reference RX 6700 XT.

A Closer Look at the Reference and PowerColor Red Devil RX 6700 XT

Although the Red Devil RX 6700 XT advertises itself as a premium 7nm 16GB vRAM-equipped card on AMD’s RDNA 2 architecture which features 1440P and PCIe 4.0, the cover of the box uses almost no text in favor of stylized imagery.

The back of the box touts key features which now include HDMI 2.1 VRR, ray tracing technology, and VR Ready Premium as well as states it’s 700W power and system requirements. AMD’s technology features are highlighted and the box features PowerColor’s custom cooling solution, Dual-BIOSes, RGB software and output LEDs, and a solid backplate.

Opening its very well-padded box, we see a quick installation guide, RGB LED cable, and an invitation to join PowerColor’s Devil’s Club. PowerColor has a nicer presentation than AMD’s reference RX 6700 XT which is rather barebones.

AMD directs you to their website for installation instructions while PowerColor includes detailed instructions.

The Red Devil RX 6700 XT is a large tri-fan card in a 2.5 slot design which is quite handsome with PowerColor’s colors and even more striking with the RGB on. Here is the Red Devil next to a reference RX 5700 XT and flanked on both sides by a RTX 3060 Ti FE and a RTX 3070 FE to show how much larger and beefier a card it is than the other three cards.

The Red Devil uses two 1×8-pin PCIe connections while the reference version uses 1×8-pin and 1×6-pin. Looking at the other edge, we can see it is all heatsink fins for cooling as is typical of Red Devil cards.

Below, the PowerColor Red Devil RX 6700 XT’s sturdy backplate features a stylized custom devil symbol that lights up in the color of your choice if synced, red being the default. There is also a switch to choose between the default overclock (OC) BIOS and the Silent BIOS. We didn’t bother with the Silent BIOS but it is good to have in case a flash goes bad.

Compare with the reference RX 6700 XT backplate which is rather plain-Jane.

The Red Devil’s RX 6700 XT’s connectors include 2 DisplayPorts, 1 HDMI connection, and a USB Type C connector. There is an LED that illuminates this panel for making easier connections in the dark.

It shares the same IO connectors with the reference RX 6700 XT below, but the Red Devil has a better system exhausting hot air out of the back of the PC.

The specifications look good and the Red Devil itself looks great with its default RGB bright red contrasting with the black backplate and its aggressively lit-up end perhaps is stylistically reminiscent of an automotive grill.

Unlike with the reference version that only lights up the logo, you may also enhance and coordinate the RGB colors by connecting to the motherboard using a supplied aRGB (5v 3-pin) connector using the DevilZone RGB software. It looks awesome.

Let’s check out its performance after we look over our test configuration and more on the next page.

Let’s check out overclocking, temperatures and noise next.

The Red Devil RX 6800 XT arrived at BTR for evaluation on a short-term loan from PowerColor on Wednesday, the same day the card launched for sale with very limited supply and with no manufacturer recommended pricing although it has been listed out of stock for $799.99 at Newegg. We have been benching it versus the $699 RTX 3080 Founders Edition (FE) and the $649 RX 6800 XT reference card that we got that same day from AMD using GPGPU, workstation, SPEC, 37 games and synthetic benchmarks. We concluded from our preliminary 9-game PC and PCVR 15-game review relative to the RTX 3080, that the reference RX 6800 XT is probably faster at pancake gaming than at VR gaming.

We will also compare the performance of these competing cards with the RX 5700 XT Anniversary Edition (AE) and the GTX 1080 Ti FE to see how older cards fare, and we also include all of the GeForce Turing Super cards and the Ampere cards to complete BTR’s 10-card Big Picture.

The Red Devil RX 6800 XT is factory clocked 90MHz higher than the reference version using the OC BIOS. According to its specifications, the Red Devil RX 6800 XT boost can clock up to 2340MHz out of the box. It also looks different from older generation classic Red Devils, arriving in a more neutral gray color instead of in all red and black. The Red Devil RX 6800 XT features a RGB mode whose LEDs default to a bright red which may be customized by PowerColor’s DevilZone software.

The testing platform uses a clean installation of Windows 10 64-bit Pro Edition, and our CPU is an i9-10900K which turbos all 10 cores to 5.1/5.0GHz, an EVGA Z490 FTW motherboard, and 32GB of T-FORCE Dark Z DDR4 3600MHz. The games, settings, and hardware are identical except for the cards being compared.

First, let’s take a closer look at the new PowerColor Red Devil RX 6800 XT.

A Closer Look at the PowerColor Red Devil RX 6800 XT

Although the Red Devil RX 6800 XT advertises itself as a premium 7nm card on AMD’s RDNA 2 architecture which features FidelityFX, FreeSync 2 HDR and PCIe 4.0, the cover of the box uses almost no text in favor of stylized imagery.

The back of the box touts key features which now include HDMI 2.1 VRR, ray tracing technology, and VR Ready Premium as well as states it’s 850W power and system requirements although there are a lot of blank and unused space on the box. AMD’s technology features are highlighted, but the box does not even mention PowerColor’s custom cooling solution, Dual-BIOSes, RGB software and output LEDs and backplate.

Opening its very well-padded box, we now see advertising that instead probably should have been on the box’s outside. Also inside are a quick installation guide, RGB LED cable, and an invitation to join PowerColor’s Devil’s Club. In addition, a couple of key caps are included which could prove useful for benchmarking while wearing a HMD. PowerColor’s is a nicer presentation than AMD’s reference RX 6800 XT.

The Red Devil RX 6800 XT is a large tri-fan card in a three slot design which is quite handsome with PowerColor’s colors and even more striking with the RGB on. Here is the Red Devil next to a RTX 3080 FE to show how much larger and beefier a card it is.

It uses two 1×8-pin PCIe connections. Above is the reference RX 6800 XT backplate.

The PowerColor Red Devil RX 6800 XT’s sturdy backplate features a stylized custom devil symbol that lights up in the color of your choice if synced, red being the default. This card is number 41 out of a 1000 limited edition set. We do not know what this means. There is also a switch to choose between the default overclock (OC) BIOS and the Silent BIOS. We didn’t bother with the Silent BIOS but it is good to have in case a flash goes bad.

The Red Devil’s RX 6800 XT’s connectors include 2 DisplayPorts, 1 HDMI connection, and a USB Type C connector. There is an LED that illuminates this panel for making easier connections in the dark.

The specifications look good and the card itself looks great with its default RGB bright red contrasting with the black backplate and its aggressively lit-up end perhaps stylistically reminiscent of an automotive grill.

Let’s check out its performance after we look over our test configuration and more on the next page.

NVIDIA Control Panel settings

Here are the NVIDIA Control Panel settings.

We used MSI’s Afterburner to set all video cards’ power and temperature limits to maximum.

AMD Adrenalin Control Center Settings

All AMD settings are set so that all optimizations are off, Vsync is forced off, Texture filtering is set to High, and Tessellation uses application settings. All Navi cards are capable of high Tessellation unlike earlier generations of Radeons.

Anisotropic Filtering is disabled by default but we always use 16X for all game benchmarks.

Let’s check out overclocking, temperatures and noise next.

BTR received the RTX 3070 8GB Founders Edition (FE) from NVIDIA and we have been testing its performance by benchmarking 35 games, and also by overclocking it. NVIDIA claims that at $499 it is as fast as the Turing Flagship, the RTX 2080 Ti, which launched at $999 to $1,199 so we compared their performance. In addition, although the RTX 3070 is a gaming GeForce card, we have added workstation, SPEC, and GPGPU benches.

We have already covered Ampere’s features in depth and we have already reviewed the RTX 3080, the 3070’s $699 faster brother that comes equipped with 10GB of vRAM. This review will consider whether the new RTX 3070 FE at $499 delivers a good value as a compelling upgrade from the Pascal GTX 1080 Ti or even from the Ampere RTX 2070 SUPER, the refresh of the RTX 2070 FE which launched at $699 two years ago.

The RTX 3070 is not based on the GA102 chip like the RTX 3080 and the RTX 3090, but rather it uses a separate smaller GA104 GPU chip. Below is the full-chip diagram.

The RTX 3070 FE uses 64 SMs, 5888 CUDA cores, 184 3rd Generation Tensor and 46 RT cores, along with 184 Texture Units and 96 ROPs. The Boost Clock is 7000MHz, and 8192MB of GDDR6 on a 256-bit memory bus provide 448GB/s bandwidth, all within a 220W total GPU power envelope.

Since we have overclocked the RTX 3070, we will compare its overclocked performance versus stock. We have added Crysis Remastered to our benching suite to see “Can it Run Crysis” at 1080P, 1440P, and at 4K. In addition, we will also post SPECworkstation3 GPU results and a brand new version of the improved SPECviewperf 2020 benchmark which released on October 15.

Besides comparing the RTX 3070 FE’s performance with the RTX 2080 Ti FE, BTR’s test bed includes the fastest Ampere cards – the RTX 3080 FE and the RTX 3090 FE – and the Turing RTX 2080 and the RTX 2070 SUPER FE. We also test NVIDIA’s flagship Pascal cards, the TITAN Xp plus the GTX 1080 Ti FE. This time, we have added AMD’s fastest Navi card, the RX 5700 XT Anniversary Edition to compare its performance also.

We benchmark using Windows 10 64-bit Pro Edition at 1920×1080, 2560×1440, and at 3840×2160 using Intel’s Core i9-10900K at 5.1/5.0 GHz and 32GB of T-FORCE DARK Z 3600MHz DDR4 on a EVGA Z490 FTW motherboard. All games and benchmarks use the latest versions, and we use recent GeForce Game Ready drivers for games.

Let’s first unbox the RTX 3070 Founders Edition before we look at our test configuration

The RTX 3070 Founders Edition Unboxing

The Ampere generation RTX 3070 Founders Edition is a completely redesigned Founders Edition and here is the card, unboxed.

Just like with the RTX 3080 and RTX 3090 Founders Editions, the RTX 3070 comes in a “shoebox” style where the card inside lays flat at a slight incline for display. However, the RTX 3070 box is much smaller and shorter than either of its siblings. The thick padding of the box protects the card.

The system requirements, contents, and warranty information are printed on the bottom of each box. The RTX 3070 requires a 650W power supply unit, and the case must have space for a 242mm (L) x 112mm (W) two-slot card. It easily fits in our Phanteks Eclipse P400 ATX mid-tower.

Inside the box and beneath the card are warnings, a quick start guide and warranty information, plus the 12-pin to PCIe 8-pin dongle that will be required to connect the RTX 3070 to most PSUs.

A completely redesigned shroud creates a new look for the RTX 3070 Founders Edition to provides a premium and solid heavy feel to its industrial design. It is a moderately heavy 2-slot card with dual fans.

Turning the card over, we see a similar unique design of Ampere FEs. This card is designed to keep the GPU cool including by using a short PCB, and inside the card is mostly all heatsink fins.

There is very large surface area for cooling so the heat is readily transferred to the fin stack and the dual fans exhaust the heat out of the back of the case and also from the top of the card into the case’s airflow.

The IO panel has a very large air vent and four connectors. The connectors are similar to the Founders Edition of the RTX 2080 Ti and the RTX 3080, but the VirtualLink connector for VR is no longer offered since HMD manufacturers are not using it. Three DisplayPort 1.4 connectors are included, and the HDMI port has been upgraded from 2.0 to 2.1 allowing for 4K/120Hz over a single HDMI cable.

In our opinion, the RTX 3070 Founders Edition is a good-looking card with a unique industrial style and it looks good in any case. The logo does not light up unfortunately.

Before we look at overclocking, power and noise, let’s check out our test configuration.

NVIDIA Control Panel settings

Here are the NVIDIA Control Panel settings.

We used MSI’s Afterburner to set all video cards’ power and temperature limits to maximum as well as for overclocking and to increase the RTX 3070’s voltage to its maximum for additional overclocking.

AMD Adrenalin Control Center Settings

All AMD settings are set so that all optimizations are off, Vsync is forced off, Texture filtering is set to High, and Tessellation uses application settings. Navi cards are quite capable of high Tessellation unlike earlier generations of Radeons.

Anisotropic Filtering is disabled by default but we always use 16X for all game benchmarks.

By setting the Power Limits and Temperature limits to maximum for each card, they do not throttle, but they can each reach and maintain their individual maximum clocks. This is particularly beneficial for high power cards.

Let’s check out overclocking, temperatures and noise next.

Overclocking, Temperatures & Noise

All of our performance and overclocked testing are performed in a closed Phanteks Eclipse P400 ATX mid-tower case. Inside, the RTX 3070 is a very quiet card even when overclocked and we never needed to increase its fan speeds manually or change the stock fan profile. Compared with the RTX 2080 Ti which becomes rather loud when it ramps up, the RTX 3070 is much quieter and can barely be heard over the other fans in our PC. We overclocked the RTX 3070 using Afterburner including adding .1mV more voltage.

We used Heaven 4.0 running in a window at completely maxed-out settings at a windowed 2560×1440 to load the GPU to 98% so we could observe the running characteristics of the RTX 3070 and also to be able to instantly compare our changed clock settings with their results. At completely stock settings with the GPU under full load, the RTX 3070 ran cool and stayed below 75C with clocks that averaged around 1900MHz.

Simply raising the Power and Temperatures to their maximums resulted in the clocks running at 1920MHz to1935MHz with no changes in temperatures whatsoever using the stock fan profile. In fact, we never needed to adjust the fan profile since the GPU never rose above 75C. It never became noisy as the fan never rose above 57%. Adding .1mV to the core didn’t make any difference to stability or to performance.

Our RTX 3070’s vRAM can overclock to 8250MHz using a +1250MHz offset with a decent performance increase, but a core overclock delivers even more significant performance. The maximum stable Heaven overclock allowed us to add +1200MHz offset to the memory and +115MHz to the core, but it was not stable in games.

Our final RTX 3070 overclock turned out to be an “either – or” scenario regarding the memory OC vs the core OC. After testing multiple combinations, our RTX 3070’s final stable overclock to achieve the highest overall performance added +100MHz offset to the core and +100 MHz to the memory as pictured above which settled in above 2000MHz. The RTX 3070 FE is power-limited, and to achieve a higher overclock will take more voltage than what + .1mV can deliver. If you want a higher overclock, pick a partner overclocked AIB.

To see the performance increase from overclocking, we tested only 7 games at all three of our regular resolutions. We live in Southern California and our power company cut the power off yesterday as we were benchmarking – so we had to cut our overclocking results short. The results are given after the main performance charts in the next section.

First, let’s check out performance on the next page.

This review follows up on the RTX 3090 Founders Edition (FE) launch review. It is the fastest video card in the world, and it is a GeForce optimized for gaming – it is not a TITAN nor a Quadro replacement. However, we demonstrated that it is very fast for SPEC and GPGPU benches, and its huge 24GB vRAM framebuffer allows it to excel in many popular creative apps making it especially fast at rendering.

The RTX 3090 is NVIDIA’s flagship card that commands a premium price of $1500, and some gamers and pro app users may consider buying a second RTX 2080 Ti as an alternative for SLI/mGPU (Multi-GPU) gaming, pro apps, SPEC, GPGPU, and for creative apps. So we purchased a EVGA RTX 2080 Ti XC from eBay and a RTX TITAN NVLink High Bandwidth bridge from Amazon to test 2 x RTX 2080 Tis versus the RTX 3090.

The RTX 3090 is the fastest video card for gaming and it is the first card to be able to run some games at 8K. But the RTX 2080 Ti is still very capable as NVIDIA’s former flagship card, and we will demonstrate how two of them perform in SLI/mGPU games, SPECworkstation3, creative apps using the Blender 2.90 and OTOY benchmarks, and in Sandra 2020 and AIDA64 GPGPU benchmarks. In addition, we will also focus on pro applications like Blender rendering, DaVinci’s Black Magic, and OTOY OctaneRender. It will be interesting to see if two RTX 2080 Ti’s pool their memory to 22GB using these pro apps versus the RTX 3090 24GB.

We benchmark SLI games using Windows 10 64-bit Pro Edition at 2560×1440 and at 3840×2160 using Intel’s Core i9-10900K at 5.1/5.0 GHz and 32GB of T-FORCE DARK Z 3600MHz DDR4. All benchmarks use their latest versions, and we use the same GeForce Game Ready drivers for games and the latest Studio driver for testing pro apps.

Let’s check out our test configuration.

NVIDIA Control Panel settings

Here are the NVIDIA Control Panel settings.

We used MSI’s Afterburner to set all video cards’ power and temperature limits to maximum as well as to set the Founders Edition clocks to match the XC’s clocks. By setting the Power Limits and Temperature limits to maximum for each card, they do not throttle, but they can each reach and maintain their individual maximum clocks better. When SLI is used, it is set to NVIDIA optimized.

So let’s check out performance on the next page.

SLI & mGPU

BTR has always been interested in SLI, and the last review we posted was in January, 2018 – GTX 1070 Ti SLI with 50 games. We concluded:

“SLI scaling is good performance-wise in mostly older games and where the devs specifically support SLI in newer DX11 and in DX12 games. When GTX 1070 Ti SLI scales well, it easily surpasses a single GTX 1080 Ti or TITAN Xp in performance. . . . SLI scaling in the newest games – and especially with DX12 – is going to depend on the developers’ support for each game [but] recent drivers may break SLI scaling that once worked, and even a new game patch may affect SLI game performance adversely.”

Fast forward 2-1/2 years to today. There are still very few mGPU games, and NVIDIA has relegated SLI to legacy. They will not be adding any new SLI profiles, and the only Ampere card that supports it is the RTX 3090 using a new NVLink bridge – for benchmarking – to set world records in synthetic tests like 3DMark. NVIDIA has this to say about SLI support “transitioning”, quoted in part:

“NVIDIA will no longer be adding new SLI driver profiles on RTX 20 Series and earlier GPUs starting on January 1st, 2021. Instead, we will focus efforts on supporting developers to implement SLI natively inside the games. We believe this will provide the best performance for SLI users.

Existing SLI driver profiles will continue to be tested and maintained for SLI-ready RTX 20 Series and earlier GPUs. For GeForce RTX 3090 and future SLI-capable GPUs, SLI will only be supported when implemented natively within the game.

[Natively supported] DirectX 12 titles include Shadow of the Tomb Raider, Civilization VI, Sniper Elite 4, Gears of War 4, Ashes of the Singularity: Escalation, Strange Brigade, Rise of the Tomb Raider, Zombie Army 4: Dead War, Hitman, Deus Ex: Mankind Divided, Battlefield 1, and Halo Wars 2.

[Natively supported] Vulkan titles include Red Dead Redemption 2, Quake 2 RTX, Ashes of the Singularity: Escalation, Strange Brigade, and Zombie Army 4: Dead War.

… Many creative and other non-gaming applications support multi-GPU performance scaling without the use of SLI driver profiles. These apps will continue to work across all currently supported GPUs as it does today.”

It looks bleak for SLI’s future and dev-supported mGPU titles are beyond rare. So we tested our 40-game benching suite and identified just nine games that scaled well with RTX 2080 Ti. Of the baker’s dozen games that NVIDIA lists and that we have, Civilization VI using the ‘Gathering Storm’ expansion benchmark did not scale, and Red Dead Redemption 2 crashed when we tried to use it. The other games on their list are old and run great on any modern GPU negating any reason to use SLI anyway, except perhaps for extreme supersampling.

We didn’t bother listing the performance of games that barely scale, scale negatively, or exhibit issues when SLI is enabled. That list is very long. Of course, there are still SLI enthusiasts who tweak their games with NVIDIA Inspector and roll back to old drivers to indulge their hobby – but we use the latest drivers without tediously trying workarounds that may or may not be successful.

Build-Gaming-Computers.com was able to identify a total of 57 games (out of many thousands) that scaled well or partially with SLI in 2020, and they have concluded that overall it isn’t worth the trouble or the expense of maintaining two finicky cards using an extra-large PSU. However, here are nine relatively modern games that we tested that show SLI scaling without a lot of microstutter or other issues associated with them.

SLI Gaming Summary Charts

Here are the summary charts of 9 games and 3 synthetic tests that scale with mGPU or SLI. The highest settings are always chosen and the settings are listed on the chart. The benches were run at 2560×1440 and at 3840×2160. The first column represents the performance of a single RTX 2080 Ti, the second represents two RTX 1080 Tis, and the third column gives RTX 3090 results. ‘X’ means the game was not tested.

Most results show average framerates, and higher is better. Minimum framerates are next to the averages in italics and in a slightly smaller font. Destiny 2, benched with OCAT show average framerates, but the minimums are expressed by frametimes (99th-percentile) in ms where lower is better.

Although SLI scaling is good with these nine games at 4K, there are some issues with 256×1440 and framerate caps. We would prefer to play these nine games with a RTX 3090 that has no issues with microstutter. However, synthetic benches look pretty good.

Even though the RTX 2080 Ti has been surpassed by both the RTX 3080 and the RTX 3090, our PC scored in the top 1% of all PCs using Fire Strike Ultra.

If you are a professional overclocker and/or want to set a world record, we would suggest buying two RTX 3090s for that purpose instead of using any two Turing video cards.

We cannot recommend SLI to any gamer unless they have a very large library of old(er) games that they revisit and play regularly and who don’t mind the issues associated with tweaking and maintaining SLI profiles using old drivers. Then there is the added inconvenience of disabling SLI each time most modern games are played. Besides, there are the additional issues of heat and noise coupled with using two powerful cards with a large PSU, not to mention the expense of buying a second card, and the higher cooling power bills associated with using SLI during the warm months of Summer.
