Phoronix: AMD R600g Performance Patches Yield Mixed Results

Following performance benchmark results I published earlier this week comparing the open-source Radeon and AMD Catalyst driver performance under Ubuntu 12.10, Marek, the well-known independent open-source graphics driver developer, set out to explore some of the performance issues in the open-source driver. One day later, he published a patch that could quadruple the frame-rate of the Radeon Gallium3D driver. He went on to push another performance-focused patch too for this R600g driver. In this article are a fresh round of benchmarks of the open-source driver to look at the wins and losses attributed to this new code.
