Mesa 10.5 vs. 10.7 Git, Linux 4.2 Kernel For Intel Iris Graphics 5100

This weekend I had out the ASUS Zenbook ultrabook with Core i7 4558 "Haswell" processor that boasts Iris Graphics 5100. I figured I'd run some Mesa 10.5 vs. 10.7-devel and Linux 4.0 vs. 4.1 vs. 4.2 kernel graphics tests.

The i7-4558U is a dual-core processor plus Hyper Threading with 2.8GHz base frequency and 3.3GHz turbo frequency. The i7-4558U features the Iris Graphics 5100 with a 1.2GHz clock frequency. From an Ubuntu 15.04 installation is where I ran the Mesa Git and then Linux kernel Git benchmarks.
Mesa 10.5 10.7-dev Intel HSW Iris
Mesa 10.5 10.7-dev Intel HSW Iris
Mesa 10.5 10.7-dev Intel HSW Iris
Only in those few tests was there a performance change for this Haswell Iris system when running the newer Mesa stack. All of the results and test details can be found via this result file.

With the Linux 4.0 vs. 4.1 vs. 4.2 kernel tests there were no performance changes via the Intel DRM driver for this Haswell Core i7 ultrabook chip, but if you want to look at those details anyways, you can find them via this result file.

As always, daily Git benchmarks of both Mesa and the Linux kernel continue to be done over on
