"When reviewing the AMD Radeon R9 290 under Linux back in November we found the Catalyst Linux performance to be quite poor for this high-end "Hawaii" graphics processor compared to the pleasurable performance reports under Windows and a strong showing against NVIDIA's wares. Even with succeeding updates we still found the R9 290 Linux performance to be poor -- and that's for the high-performance Catalyst driver over the open-source RadeonSI Gallium3D-based driver. In this article are fresh benchmarks of the high-end NVIDIA GeForce and AMD Radeon graphics cards from Ubuntu Linux using the latest beta graphics drivers."
