Intel Core i7 Haswell Benchmarks On Linux 3.12

So far in our testing of the Linux 3.12 kernel we have found that there are some file-system performance improvements and most noticeable is AMD Radeon performance improvements for the open-source driver. We have also found the AMD APU performance hasn't changed much and Ivy Bridge graphics are rather unchanged among other mute workloads, but is there any other worthwhile performance improvements to be discovered? Our latest Linux 3.12 Git tests are from the System76 Galago UltraPro with Core i7 4750HQ "Haswell" processor as we benchmark every major kernel release going back to Linux 3.8.

The System76 Haswell ultrabook had the Core i7 4750HQ with Iris Pro 5200 graphics, 8GB of RAM, and 120GB Intel SSD. Xubuntu 13.10 x86_64 was the base operating system while changing out the Linux 3.8, 3.9, 3.11, and 3.12 Git vanilla kernels from the Ubuntu mainline kernel PPA.

Being tested in this article via the Phoronix Test Suite was a wide variety of tests ranging from graphics to disk and computationally bound benchmarks.
