Intel Iris Graphics With Linux 3.15 & Mesa 10.3-devel

Following the benchmarks I posted this morning showing Intel Haswell graphics having some OpenGL slowdowns with the newer Mesa graphics driver code, I tested a sharply different Haswell system to see if the performance differential was also to be found on this Intel ultrabook with Iris Graphics 5100...

The tests this morning where some performance regressions were noted was with a desktop system having an Intel Core i7 4770K processor with HD Graphics 4600. For this second round of testing I used my ASUS Zenbook UX301LAA ultrabook, which has a Intel Core i7 4558U processor with Iris Graphics 5100. Iris Graphics are more powerful than the HD Graphics found on the aforementioned Core i7 desktop CPU.

With this testing I ran Ubuntu 14.04 LTS in its stock state with all stable release updates as of this morning. I then loaded in the Oibaf PPA for Mesa 10.3-devel, etc. I then used the Ubuntu Mainline Kernel PPA for the latest daily of the Linux 3.15 kernel -- similar to the testing done with the Intel HD Graphics results shared earlier today. All benchmarking was done via the Phoronix Test Suite.

No performance regressions were found with the Iris Graphics 5100 when using the updated Mesa 10.3-devel i965 DRI driver nor with the latest Git of Linux 3.15. More of today's Iris Graphics Ubuntu Linux test results from the ASUS ultrabook can be found via 1405252-PTS-UBUNTUIR02. To compare your own system's performance to these Iris Graphics 5100 OpenGL numbers, simply run phoronix-test-suite benchmark 1405252-PTS-UBUNTUIR02.
