AMD Catalyst 15.7 Linux Benchmarks: R9 290 Hawaii & R9 285 Tonga

I'm in the midst of a new large open-source and (separately) closed-source NVIDIA/AMD Linux graphics card comparison on the latest drivers as part of an upcoming Radeon R7 370 Linux review and to be followed by R9 Fury Linux benchmarks. However, for those interested in the Catalyst 15.7 benchmarks on Linux, I ran some quick tests with a Radeon R9 285 and R9 290.

Tested was the fglrx 15.20.2 driver as packaged on Ubuntu 15.04 along with the Catalyst 15.7 driver (fglrx 15.20.3). The Catalyst 15.5 driver couldn't be tested due to issues on this system with Ubuntu 15.04. It's quite a straight-forward comparison and just this quick, one-page article.
This was the exciting result... Team Fortress 2 that improves quite a bit with this new driver update.

However, other OpenGL and OpenCL titles tested (including Linux games like Counter-Strike: Global Offensive and Metro Last Light Redux) were unaffected with the R9 285 and R9 290. You can see all of the test results via this OpenBenchmarking.org result file. Stay tuned for some more interesting Linux driver tests shortly.
