Radeon Gallium3D Is Running Increasingly Well Against AMD's Catalyst Driver
Written by Michael Larabel in Display Drivers on 5 August 2014. Page 4 of 4. 35 Comments

When running Xonotic with high image quality settings, the performance becomes more CPU bound, but R600/RadeonSI Gallium3D is ~70%+ the speed of Catalyst on Ubuntu Linux.

With the last three tests, the RadeonSI Gallium3D driver failed to work due to AMD GPU LLVM back-end errors with the version of LLVM used by the Oibaf PPA on Ubuntu 14.04 LTS. However, for the Radeon HD 6000 series hardware it shows good performance out of the open-source stack, particularly for the HD 6770/6870.

Overall these results today are very good for both the R600g/RadeonSI drivers on Mesa 10.3-devel with the Linux 3.16 kernel. Coming up next will be the power efficiency results between the open and closed AMD Linux drivers followed by trying out Linux 3.17 Git to finally have a look at the open-source Radeon R9 290 Hawaii GPU performance.
