AMDGPU-PRO 17.50 vs. RADV/RadeonSI Radeon Linux Gaming Performance

First up was the OpenGL-using BioShock Infinite game. AMDGPU-PRO 17.50 with the closed-source OpenGL driver remains noticeably slower than the open-source RadeonSI driver stack... The Radeon RX Vega 64 with AMDGPU-PRO 17.50 is noticeably slower than the Radeon R9 Fury on open-source even. The RadeonSI performance edge of the RX Vega 64 is 25% better than AMD's long-standing, cross-platform, binary-only driver. In this particular game, the latest RadeonSI code in Mesa Git is performing very well against NVIDIA with the RX 580 coming ahead of the GTX 1060 and the RX Vega 64 even beating the GTX 1080 in this rather CPU limited game by today's standards.

With Counter-Strike: Global Offensive it's another case where RadeonSI is still doing better than AMDGPU-PRO's OpenGL driver. Here the RX Vega 64 is 25% faster again than the PRO OpenGL driver. But there's still more room to push the RadeonSI performance higher as the RX Vega 64 is still well short of the GTX 1070 Ti / GTX 1080.

RadeonSI runs past the AMDGPU-PRO 17.50 OpenGL driver as well with Deus Ex: Mankind Divided, one of the most demanding games currently available on Linux.
