AMD Radeon R600 Gallium3D Performance Over The Past Two Years

Lastly are some synthetic OpenGL tests.

The R600g performance has improved over time, but has largely plateaued as of late.

The R600g driver today is certainly in much better shape than it was two years ago, but there hasn't been any dramatic performance changes to it recently. Most of the open-source AMD Linux developers are busy enough with the RadeonSI Gallium3D driver for supporting the HD 7000 series (GCN) GPUs and newer, while R600g is still marching along but to a slower beat. Similarly, it's with Mesa 11.0/11.1-devel that there's OpenGL 4.1 support for RadeonSI but currently only OpenGL 3.3 for R600g, with the necessary GL support still being tackled by independent developers.

Coming up later this week will be similar tests when using the RadeonSI driver with a Radeon Rx 200 series graphics processor. Following that I might also run some fresh Linux open-source Git vs. Catalyst benchmarks and whatever other Linux graphics comparisons end up getting requested by Phoronix Premium subscribers and those viewing the site with ads enabled that make all of this Linux hardware testing possible on a daily basis. There will also be Nouveau tests in short order of their reworked driver for Linux 4.3.
