With the aging but still relevant Doom 3 test, we see both the HD 7950 and R9 270X graphics cards instantly become multiple times faster when moving to the Linux 3.13 kernel from Linux 3.12. It was possible to manually enable DPM on earlier kernels, but there are some bugs. For Linux 3.13 most AMD GPUs should be in good shape for handling this dynamic power management feature. For Radeon HD 7000 series GPUs and newer is also the important render back-end fix plus other improvements.

If you look at where the performance was on Ubuntu 13.10 "out of the box", these results are even more amazing and will be shared in the coming days/

Is the RadeonSI Gallium3D + Linux 3.13 DRM performance now enough to match the Catalyst performance numbers? Stay tuned to Phoronix to find out these exclusive Ubuntu Linux OpenGL performance numbers.
