Phoronix: RADV Vulkan Driver Ends The Year On A High Note With A Performance Boost

Just hours ago was a new patch series being merged to Mesa Git by RADV co-founder Bas Nieuwenhuizen to allow for correct DCC usage. I have just finished up my initial benchmarks of those RADV changes and they indeed help the few Radeon GPUs tested.

Great improvements but so boring that i still compare against OpenGL performance.

What a great way to end 2018

Happy New Year 2019!

Fantastic job guys!

For this and the whole of 2017 efforts on RadV. Have a beer!!

Thanks Bas & Dave!
With such performance numbers I personally don't really see the point of AMDVLK.
Code sharing between vendors and APIs seems more efficient than with closed&bloated OS, at least for now.

And of course thanks to Michael for all these benchmarks! Cheers!

Code sharing between vendors and APIs

like between dx12 and vulkan? sure

Nvidia's Linux Vulkan driver which is cross-platform (shared with windows) is way faster than RadV.
And AMD's windows Vulkan driver is even faster than that Nvidia driver: when comparing competing GPUs. And that comes from the same shared codebase as amdvlk.

So don't be to quick to dismiss the potential in that AMD codebase. Once they spend some time optimizing performance of it on Linux it could run as blazing fast as their Windows Vulkan driver.
That would mean results such as the below in Vulkan applications and not by narrow margins either
R9 290 > gtx 970
rx580 > gtx1060
vega56 > gtx 1070
vega64 > gtx 1080

I think it's more likely that the AMD OpenGL Windows driver is worse then the NVIDIA OpenGL counterpart. The Vulkan driver is likely catching up...

Just wondering what benchmarks these results are on? is there dota2 windows benchmarks someplace, I can see a lot of the ported dx11 games being slower on Linux due to port overheads, but I'm not seeing why amdgpu pro would have have much different perf between windows and Linux, like the kernel API can't be that different.

VKmark's looking low for the 64!

Just done a run on mesa 17.3.1 and scored 18753.

Has radv actually regressed on the git branch?
