For the past week on Phoronix since the public debut of Intel's Haswell processors there has been a lot of coverage. The CPU performance is generally great but the Haswell Linux graphics support is still a work-in-progress even though its performance has already evolved a lot. This Sunday are some extra Core i7 4770K benchmarks.

In looking for any Haswell Linux graphics improvements with forthcoming kernel updates, yesterday (Saturday, 8 June) I ran some more Linux kernel tests. Building upon the earlier results published this week comparing updates on Ubuntu 13.04, the latest mainline Linux 3.10 kernel was tested as of 8 June plus then the drm-intel-next and drm-intel-nightly trees.

For easy reference and comparison, the tested kernels were obtained from the Ubuntu Mainline PPA. A few of the benchmark results are embedded below while all of the system details, system logs, and OpenGL performance benchmark results can be found on OpenBenchmarking.org via 1306096-UT-HASWELLLI82.

Long story short, if you were hoping for some immediate Haswell performance upgrades if trying out drm-intel-next or drm-intel-nightly over the current Linux 3.10 kernel, it doesn't appear that way... At least not for the Intel Core i7 4770K with HD Graphics 4600. But if you're still on Linux 3.8 or earlier, it's surely worth the performance upgrade to try out Linux 3.10.

Stay tuned for more Intel Haswell Linux benchmarks on Phoronix coming at the start of next week.
