Radeon TONGA Sees Some Gains With AMDGPU DRM-Next 4.12
Over the past few days I have posted some RX 480 tests and R9 Fury OpenGL/Vulkan tests for the new AMDGPU code slated for Linux 4.12. I've also carried out some R9 285 "Tonga" tests and happy to report seeing some performance gains there too.
Mostly in line with the AMDGPU DRM-Next gains found with the R9 Fury and RX 480, the R9 285 is doing better in some workloads too, while it also gained in a few other tests.
Mesa 17.1-dev on this Ryzen box and was comparing Linux 4.11 Git to DRM-Next as of this past week. The R9 Fury results are here for reference purposes while the RX 480 numbers are available from the link above.
The R9 285 appears to have a small boost with CS:GO on DRM-Next.
Similar to the Polaris and Fiji GPUs, Tonga is seeing better performance with DRM-Next for Dota 2 Vulkan.
The Tonga card even sees a boost with Dota 2 OpenGL.
ET: Legacy also ends up now performing on par with the R9 Fury in this Enemy Territory game test ported to its OpenGL 3 renderer.
There seems to be a big fix with the R9 285 for Metro Last Light Redux.
Xonotic even sees a small improvement with the R9 285 on DRM-Next.
More data via this OpenBenchmarking.org result file. Overall I am quite excited about the AMDGPU changes for Linux 4.12 in regards to some clear performance improvements, even without this kernel getting DC (DAL) or Vega display support. More tests coming include a fresh Radeon vs. AMDGPU driver roundabout.
