3-Way RadeonSI Gallium3D vs. Catalyst Benchmarks
In the past few days I have delivered a number of RadeonSI stories including:
- AMD's RadeonSI Gallium3D Is Improving, But Catalyst Is Much Better
- RadeonSI Color Tiling Brings OpenGL Performance Boost
- AMD RadeonSI GLAMOR 2D Benchmarks
- RadeonSI Gallium3D Gets UBO/TBO Support
This weekend I had ran some new Mesa 10.0-devel + Linux 3.12 kernel benchmarks with Radeon DPM enabled and used the Radeon HD 7850, Radeon HD 7950, and Radeon R9 270X graphics cards. This comparison was limited in the hardware I could test due to the lack of having any other Southern Islands hardware...
The benchmarking happened from an AMD FX-8350 system using the Phoronix Test Suite. As with my earlier RadeonSI Gallium3D tests, there's still a large difference in performance between the open and closed-source AMD Radeon GPU Linux drivers. In some of the tests there isn't much change between the three GPUs since some of the basic tests were CPU-limited and as well there isn't too much change from the HD 7850 / HD 7950 / R9 270X, but alas the lack of other hardware had limited this comparison.
The results are pretty much as expected...
With some of the tests, there was bad rendering like with Furmark that explains why RadeonSI appears faster.
