specs:
amd ryzen 5950x (water cooled)
64gb ddr4 4000 cas 19
amd reference 6900xt (water cooled)
gigabyte x570 aorus master f33 (water cooled)
sam enabled
windows 10 19043.1055
amd driver 21.5.2

did the same tests with arch (kernel 5.12.12-arch1-1, mesa 21.1.2) and RADV:

your vulkan under windows is slightly better (~18fps more) but opengl is significantly regressed compared to both my linux opengl (~37fps less) and vulkan (57fps). even your vulkan (75fps). amd opengl performance on windows is pretty terrible.

with your 241fps on windows vulkan puts it on line with the 3080 results on the linux testing michael did. seems like regardless windows or linux, some vulkan optimizations are needed.

thanks for testing windows though. i no longer have windows so its nice to see others who do to compare to linux.

that's nearly identical with what i got too.

its nice to see mesa heavily competitive against amd's proprietary opengl and vulkan though. mesa opengl clearly superior and vulkan right on the heels.

middy thanks for your input.

i've installed amdvlk in comparison to radv and that's the result: https://abload.de/image.php?img=grav...k_003hnkw4.png

radv is a liitle bit slower but as far as i can tell less power hungry. but it was only one loop each, so i'm not sure that it is representative.

dumb question: i can use amdvlk with mesa drivers? Michael is it possible you crosstest that statement with your amd grphic cards?

not a dumb question. you can switch between amdvlk and radv. i think amd did an update to amdvlk to make it even easier to switch between the two.

Yes, i did know that it is possible to have both installed but i wasn't sure if amdvlk needs the proprietary driver. But it doesn't so the results should be valid. Thanks again for your feedback.

Strange how AMD's performance scaled worse as resolution went up. Normally I would think it'd get better, seeing as they have more VRAM. But, perhaps this benchmark doesn't really stress VRAM much.

Likely isn't a VRAM sensitive benchmark, in which case I'd expect NVIDIA to scale better with resolution.

I do find NVIDIAs OpenGL performance off; historically they've had excellent OpenGL performance (compared the ATI/AMD) so it's a bit odd they're so ahead in Vulkan, but so behind in OpenGL.

And this is a big problem for Linux.
Vulkan multi-GPU support is not working at all.
Linux multi-GPU support is not available with Nvidia drivers.

Direct3D12:

2080Ti: 172.9 FPS (28872)
6700XT: 153.6 FPS (25652)

2080Ti x2 Split mode: 211.4 FPS (35300)
2080Ti x2 Alternate mode: 308.5 FPS (51524)

2080Ti + 6700XT Split mode: 199.8 FPS (33369)
2080Ti + 6700XT Alternate mode: 284.5 FPS (47524)

The new benchmark version is available for download.
Everything is ready for Vulkan and Linux multi-GPU support.

GravityMark v1.3 is ready with Vulkan multi-GPU support. Not available with Nvidia GPU because Linux driver is not supported multi-GPU configurations. But AMD should work fine. Cross-platform and cross-API Leaderboard is here: https://gravitymark.tellusim.com/leaderboard/
