Phoronix: AMDGPU-PRO 16.60 Vulkan vs. Mesa 17.1-dev RADV Performance

Given yesterday's release of the AMDGPU-PRO 16.60 driver I've been busy running various benchmarks on this first AMD Linux hybrid driver release of 2017. A number of OpenGL benchmarks will be published this weekend compared to the latest Mesa RadeonSI Git driver while for your viewing pleasure today is a look at the Vulkan performance of AMDGPU-PRO 16.60 compared to the Linux 4.10 + Mesa 17.1-dev driver stack for Dota 2 and The Talos Principle.

talos on smaller resolution is notably missing

The game seems to have some issues with it taking affect from the way the benchmarking happens, so just did native resolution due to that talos issue.

So, although amdgpu-pro's Vulkan driver comes out ahead in almost all tests (except the one with the strange resolution of 1280x1080), it seems at this point speed differences still mostly depend on the driver implementation. Nevertheless, perhaps it is significant that AMD's Vulkan implementation is the fastest even though relatively new as well (even if not as new as RADV).

Isn't Vulkan supposed to be low-level? How can there be such a vast difference in performance between drivers when the API is low level?

radv is missing some features that relate to perf

wow the kernel 4.10, Mesa gets good , no a'm a user that uses Boinc, will MESA support BOINC out off the box or do we need to install the amd-gpu-driver pack ?

[ResponseWriter]

I believe someone reported when the Talos Vulkan support was first released that the framerate is more stable. Are any stats on min/max framerates available? I guess the brackets for margin of error give a slight indication.

Otherwise it's good to know which renderer to choose. Thanks, Michael!

Michael marek is there any room for improvements RadeonSI OpenGL perf on Dota or is it at it's hardware/driver limits?

I'm asking this because the OpenGL performance is the same as AMDGPU-PRO's vulkan performance

AMDGPU PRO vulkan driver is very fast compared to RADV.
But it is still slow compared to the Nvidia proprietary driver. Hope it gets faster in the next release...

If you look at Vulkan results on windows an rx 480 will beat a 1060. An R9 fury will beat a 980.. etc. A year after the release of vulkan it looks like AMD users still don't have a competitive driver for it on linux, either open or closed source.
