Radeon RX Vega 64: AMDGPU-PRO vs. DRM-Next + Mesa 17.3-dev

For those wondering how the RadeonSI and RADV open-source driver performance is fairing for the Radeon RX Vega 64 compared to the AMDGPU-PRO hybrid driver, here are some fresh benchmarks.

Here's the latest open-source vs. closed-source (hybrid) driver benchmarks. The AMDGPU-PRO 17.30 was used as the latest hybrid driver release; the 17.40 "mining" beta driver was attempted as well, but found to be too unstable for gaming. On the open-source driver side meanwhile was the AMDGPU DC next code that's set to be merged for Linux 4.15. On the user-space side was Mesa 17.3-dev built against LLVM 6.0 SVN, provided by the Padoka PPA.

All of these Radeon RX Vega 64 Linux benchmarks were carried out on Ubuntu 17.04 and done so in a fully-automated and reproducible manner using the Phoronix Test Suite benchmarking software.

Counter-Strike: Global Offensive was 29% faster with the RadeonSI OpenGL driver than the closed-source OpenGL in AMDGPU-PRO.

Even with the demanding Deus Ex: Mankind Divided game, the performance was noticeably better when using RadeonSI.

Mad Max with OpenGL does significantly better using RadeonSI rather than AMDGPU-PRO.
