Here are some other end-of-year benchmarks I had been working on in looking at the current performance of Mesa 17.2.2 versus 17.3.1 versus 17.4-devel Git with RadeonSI OpenGL on three different graphics cards.

These latest benchmarks are with an RX 580, R9 Fury, and RX Vega 64 in looking at the three latest Mesa branches -- Mesa 17.2.2 was from the Ubuntu 17.10 archive, then Pkppa providing the current Mesa 17.3.1 stable, and then Mesa 17.4-dev built against LLVM 6.0 SVN.

Via the Phoronix Test Suite a range of benchmarks were run with RadeonSI.

For the most part the RadeonSI Gallium3D performance gets better each step of the way.

Sometimes, the differences are small.

In some instances are Vega regressions.
