Test Configuration – Software

  • GeForce 460.89 used for the RTX 3090 and the RTX 3080
  • GeForce 456.96 for the RTX 3070, the RTX 2080 Ti, and the RTX 2070/2080 SUPER; and GeForce 456.16 Press drivers and GeForce 456.38 public drivers (functionally identical) are used for the other GeForce cards.  There have been no general game performance driver improvements since Ampere launched.
  • Adrenalin 2020 Edition 20.12.2 drivers used for the Red Devil RX 6900 XT and RX 6800 XT; 20.12.1 used for the RX 6800.  Adrenalin 2020 Edition 20.10.1 drivers used for the RX 5700 XT Anniversary Edition.
  • High Quality, prefer maximum performance, single display, set in the NVIDIA control panel.
  • VSync is off in the control panel and disabled for each game
  • AA enabled as noted in games; all in-game settings are specified with 16xAF always applied
  • Highest quality sound (stereo) used in all games
  • All games have been patched to their latest versions
  • Gaming results show average frame rates in bold including minimum frame rates shown on the chart next to the averages in a smaller italics font where higher is better.  Games benched with OCAT show average framerates but the minimums are expressed by frametimes (99th-percentile) in ms where lower numbers are better.
  • Windows 10 64-bit Pro edition; latest updates v2004. DX11 titles are run under the DX11 render path.  DX12 titles are generally run under DX12, and multiple games use the Vulkan API.

NVIDIA Control Panel settings

Here are the NVIDIA Control Panel settings.

We used MSI’s Afterburner to set all GeForce video cards’ power and temperature limits to maximum and used Wattman for the Radeons.

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 didn’t spend any time overclocking the Red Devil RX 6900 XT for this review as it will be covered in Part 3 later this week (after VR), and we plan to measure the power that the card actually draws compared with the RTX 3090.  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 is even a bit quieter than the RTX 3090 which is a relatively quiet flagship card – especially compared with the Turing flagship (RTX 2080 Ti).

The Red Devil RX 6900 XT is factory clocked 90MHz higher than the reference version at 2250MHz using the OC BIOS.  According to its specifications, the Red Devil RX 6900 XT boost can clock up to 2340MHz out of the box. From our benching, we generally see it boosting even higher and it generally settles in above 2380MHz with peaks above 2400MHz.

Above are the PowerColor Red Devil RX 6900 XT Wattman default settings including the the power limit set to default while running a 98% GPU load while looping the maxed-out Heaven 4.0 benchmark.  For this card, the performance didn’t matter whether the power limit was set to default or higher.

The Red Devil’s temperatures stay low in the mid-70s 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 card.

Let’s head to the performance charts to see how the performance of the Red Devil RX 6900 XT compares with 11 other cards.



  1. Very good review , thanks.
    The compute benchmarks are very helpful.
    Giving verdict based on price should be left out I’d say right now, as a rx 6800xt/rtx 3080 costs around ~ 1000 € here, 1700+ € for a rtx 3090 and 1300 – 1400 € for a rx 6900xt.
