Benchmarks Of Ubuntu 17.04 Beta vs. Antergos, Clear Linux, openSUSE Tumbleweed
For the OpenGL graphics tests we don't have Clear Linux results since they don't ship with Radeon support (or any non-Intel accelerated graphics).
Ubuntu 17.04 does much better than Ubuntu 16.10 with the switch from Mesa 12.0 to Mesa 13.0 plus having newer DRM from Linux 4.10 vs. Linux 4.8. However, Ubuntu 17.04 has yet to pull in Mesa 17.0 for offering the best open-source graphics support...
Mesa 17.0 though is still expected to land for Ubuntu 17.04, so there is faster graphics support still ahead along with the other features brought by Mesa 17.
