RADV vs. AMDGPU-PRO Vulkan Performance vs. OpenGL In May 2017

Just saying except for Dota which it seem to be hitting a slow path or a bug and the rx 580 that obviously have issues, RADV got pretty damn close to AMDGPU-pro, I would dare To sat that in 2 months from now maybe useless to open up the closed driver beyond AMD patching certain stuff here and there.
Great work RADV guys

He, he, Michael should just setup AM1 Athlon 5350 (4 cores but slow singlethread) with disabled integrated GPU, plus RX 470 that would be CPU bound at any time on FullHD, but will show threading API differences... Like Playstation 4 PRO simulation, only with half amount but the same type of CPU cores... GNM flies there
Does generic lower level Vulkan API (in comparison to GL) can do something similar is yet to be seen
Maybe not on Phoronix, as Michael seems likes his Kaby and 4K screen so much
Or Ryzen 7 downclocked to something like 2.4Ghz and disabled HT, turbo... that should do a job tooLast edited by dungeon; 12 May 2017, 08:33 PM.

Great work RADV guys
but all except one benchmark here was run at 4K. This makes it look closer to the amdgpu pro vulkan implementation.

Originally posted by marek View PostVulkan only has lower CPU overhead, but GPU performance is unaffected if both GL and Vulkan program the GPU in the same way. If GL uses different/better GPU programming, it can be faster.
what changes is the CPU, the mesa version (17.1.0 vs 17.2-dev) and kernel (4.11.0 vs 4.12.0-git). GPU, we have both a RX480
Looking to the data, Michael have a lot better performance in the OpenGL than me, for vulkan my and his performance is similar.
I would say that kernel do not make that difference, unless there was a miracle patch somewhere
mesa-dev, maybe the new multithread patch adds more performance, but that is a too huge difference to be just that, so my bet is the CPU
Michael is using a I7 7700 and i'm using a A10 7980k... he get better single thread performance and more threads than me. So my opengl must be taking a huge hit due to the weaker cpu
I will try the mesa 17.2-dev and see if this changes in any way
