For those curious how Mesa 17.1-devel Git is performing relative to the Mesa 13.0 and 17.0 stable series, here are some Mesa Git benchmarks on three different Radeon graphics cards.
Mesa was tested from its Git branch as of Friday as well as the 13.0 and 17.0 Git branches with the latest back-ported changes to these stable series. Each of the Mesa releases were tested out-of-the-box without specifying any extra environment variables or manual modifications. The Linux 4.11 Git kernel was used throughout testing on this AMD Ryzen 7 1800X test system. This article is just looking at the RadeonSI Gallium3D OpenGL performance and not the RADV Vulkan evolution in this article.
The graphics cards used for testing included the Radeon R9 285, Radeon RX 480, and Radeon R9 Fury for Tonga, Polaris, and Fiji coverage, respectively. All of these OpenGL benchmarks were carried out in a fully-automated and reproducible manner using the open-source Phoronix Test Suite benchmarking software.
