Intel vs. Radeon vs. Nouveau On Linux 3.15 + Mesa 10.3-devel
The hardware for today's comparison was limited by running into an above-average number of regressions within the Radeon and Nouveau drivers at this stage in the Linux kernel development cycle. For the AMD hardware the newer "GCN" hardware was problematic and ultimately none of those graphics cards successfully finished our array of OpenGL benchmarks. The current AMD problems are outlined within Newer AMD Radeon GPUs Have Had A Tough Time With Linux 3.15. Open-source AMD developers are currently work to address these issues but at the time of testing they hadn't yet successfully mainlined any of the necessary fixes.
