AMD Catalyst vs. Radeon Gallium3D On Linux 3.1

Written by Michael Larabel in Display Drivers on 13 October 2011 at 08:38 AM EDT. Page 3 of 3. 20 Comments.

The VDrift racing game results remain mixed, which is due to Mesa/Gallium3D not handling some of the shaders correctly and other incorrect renderings.

With the minimally-demanding OpenArena game, the Catalyst driver is around 65% faster than the Mesa 7.12-devel + Linux 3.1 stack.

The Gallium3D driver continues playing catch-up with the Catalyst driver on Linux. At least for the Radeon HD 4000 series, the Linux 3.1 kernel doesn't offer any real performance advantages. From other Phoronix testing carried out of this new kernel, there also aren't any major performance improvements to note for other generations of Radeon hardware. For more open-source versus closed-source Radeon graphics benchmarks under Linux, see The Most Comprehensive AMD Radeon Linux Graphics Comparison from last month where more than two dozen ATI/AMD graphics cards were benchmarked on Gallium3D and Catalyst.
