Phoronix set out to benchmark the changes to Ubuntu and the Linux kernel as it relates to graphical performance using AMD GPUs, specifically the ATI Mobility Radeon X1400 128MB. The review tracks the changes from Ubuntu 9.4 to 11.4 and the 2.6.28 to 2.6.38 kernels as well as a variety of graphics drivers, both MESA and Gallium 3D. Check out what they found in the full article.
"The open-source ATI/AMD Radeon Linux driver stack has made a lot of improvements in recent times with their Gallium3D drivers becoming mature across all generations and support for new features (such as DRI2 page-flipping) landing in the mainline code and beginning to make its way to users. The time required to bring up support for new generations has also been reduced greatly and with the Radeon HD 8000 series there should be a turning point for their open-source strategy. In this article, we are providing an updated look at the course of the open-source driver’s performance for the past two years."
