Are Intel Iris Pro 6200 Graphics Fast Enough For Steam Linux Gaming?

While I'm still working on my full Intel Core i7 5775C Linux review of this socketed Broadwell processor with Iris Pro Graphics 6200, and still working through some strange issues, I do have some Steam Linux gaming figures to share tonight for those interested in how Intel's latest-generation Iris Graphics are performing with the open-source Mesa driver stack.

As a teaser until more exhaustive tests are complete, I ran some tests tonight of the Core i7 5775C while running on an Ubuntu 15.10 development system with the Linux 4.2 Git kernel and Mesa 10.5.8. Git Mesa tests and comparisons to other hardware will come in the featured, multi-page articles. These numbers are just for those that have been excited to see how Broadwell Iris Graphics are looking under Linux.

Via the Phoronix Test Suite, I ran some Team Fortress 2 and Counter-Strike: Global Offensive tests on this Intel Iris Graphics setup.
At 1080p, the Linux 4.2 + Mesa 10.5.8 stack was running with a 69FPS average for Counter-Strike: Global Offensive.
Team Fortress 2 at 1920 x 1080 was running about twice as fast.

You can find all of these TF2/CS:GO Broadwell Linux Iris Pro Graphics numbers via this OpenBenchmarking.org result file. While waiting for the full review and many other tests in the days ahead, for reference there are the recent numbers for these same two Steam Linux games with AMD GPUs on the open-source driver and the open-source NVIDIA (Nouveau) driver where with some basic OpenBenchmarking.org magic you can do your own little comparison. Or if running phoronix-test-suite benchmark 1507139-BE-STEAMLINU16 you can see how your own Linux system compares for these two games at the different resolutions against the i7-5775C (assuming you have Steam Linux setup in a default configuration).
