With Ubuntu 13.10 was when the RadeonSI support started to become usable for the R9 270X while in Ubuntu 14.04 is when the driver started to become performant. Since then the performance has continued to evolve nicely.

Ignore the duplicate identical results for Ubuntu 13.10/14.04 in this OpenArena run due to a problem with the renderer at that time. Even with Ubuntu 15.04, the performance of RadeonSI has continued to improve. As shown by other recent tests of Mesa Git and AMDGPU LLVM, the performance for HD 7000 / Rx 200 series GPUs continue to improve, but due to the aforementioned R9 270X issue, it's a pity we weren't able to test the latest Git code for this article.

Tesseract is still showing nice improvements for RadeonSI.

Year-over-year, RadeonSI is making very nice gains in performance.
