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

The minimum resolution tested was 800 x 600 for ensuring Dota 2 was rather CPU bound. In this context, the Vulkan performance for both the RX 480 and R9 Fury was faster with AMDGPU-PRO 16.60 than with Mesa 17.1-dev RADV Git by a few frames per second.

In contrast, when running with the OpenGL renderer, Dota 2 was faster with RadeonSI Gallium3D than the binary AMDGPU-PRO 16.60 OpenGL driver. When comparing the OpenGL and Vulkan results, RADV is slower than RadeonSI Gallium3D at 800 x 600 for this game while the AMDGPU-PRO 16.60 performs much better with Vulkan than OpenGL (about 40% faster).

At 1280 x 1024, the AMDGPU-PRO with the official Radeon Vulkan driver was just under 40% faster than the current RADV development code.

But again when switching over to the OpenGL renderer, RadeonSI does much better than AMDGPU-PRO's OpenGL driver.

The results at 1080p are similar.
