Intel's Core i7 5960X Is Fast & Wonderful Under Linux

After my first X99 motherboard burned up in a strange situation, since yesterday my Core i7 5960X Haswell-E system started working wonderfully with Linux after using a different motherboard. I've been hammering the system hard for the past day and no X99/i7-5960X issues have come about (albeit I've refrained from doing any overclocking or DDR4 tweaking yet) and this high-end $1000+ (USD) CPU is running great under Linux.

I'll have my full Linux review with benchmarks of the Core i7 5960X on Phoronix in the next day or two along with X99 motherboard reviews and DDR4 Linux memory tests to follow along with other interesting benchmarks from this super high-end setup with eight-core CPU plus Hyper Threading.

I'm really pleased with the i7-5960X now that it's finally setup and working. As some preview figures, I uploaded a number of standalone result files using the Phoronix Test Suite to My formal write-ups will compare the i7-5960X against an assortment of other single-socket AMD and Intel systems, but these numbers today are just for preview purposes or if you want to run your own automated, fully-reproducible, side-by-side comparisons with the Phoronix Test Suite.

1409098-LI-COREI759612 - An assortment of Linux benchmarks with the i7-5960X on Ubuntu 14.04 LTS with the Linux 3.17 kernel. This is probably the result file of interest to most readers.

409097-LI-COREI759604 - This result file contains more of the scientific-focused workloads on this Haswell-E setup, including HPC Challenge (HPCC), Rodinia, etc.

1409097-LI-STEAMLINU31 - Some Steam on Linux gaming benchmarks with this CPU paired with a Radeon HD 6870 graphics card on the mature open-source R600 Gallium3D graphics driver using the recent Mesa Git and Linux 3.17 kernel. (More graphics tests are forthcoming powered by this insanely powerful rig.)

As usual with supporting the upload of system logs, for those interested there is the /proc/cpuinfo data for this new CPU.

Again, a lot more formal testing articles with this high-end 16-thread setup will be published on Phoronix in the days and weeks ahead. You'll see this powerful i7-5960X CPU as the basis for many Phoronix compiler benchmarks, kernel tests, etc going forward. If you have any other test requests, let me know via Twitter.
