Testing The Open-Source "RADV" Radeon Vulkan Driver vs. AMDGPU-PRO

First up are 800x600 tests for being CPU bound to see the difference with the OpenGL and Vulkan performance.

The RadeonSI and AMDGPU-PRO performance is about the same...

Fun to note that the overall CPU usage is clearly lower with RadeonSI Gallium3D than AMDGPU-PRO's OpenGL driver...

Our first look at some RADV numbers... Here we see that at least at this CPU-limited resolution the performance between the RADV Vulkan driver and AMDGPU-PRO is actually quite close. With the R9 285, it's even a few frames faster on RADV. It's also good to see that for both of these drivers their frame-rates using the Vulkan renderer are higher than under OpenGL.

The CPU usage between the two drivers meanwhile were quite similar.
