Intel Core i7 5775C: Once Going, This Broadwell CPU Is Great On Linux

For the C-Ray multi-threaded ray-tracer, the i7-5775C was the fifth fastest system tested in the bunch with only being outperformed by the Xeon and Extreme Edition systems in our test lab.

Well, that's the Core i7 5775C Linux testing that's been accomplished thus far. Follow-up articles will look at the i7-5775C on different Linux kernel / Mesa releases, GCC vs. LLVM Clang compiler testing, and other tests -- your suggestions and what you'd like to see can be directed to Phoronix on Facebook / Twitter or by commenting in the forums.

From these CPU results there obviously isn't much of a reason to upgrade to the i7-5775C from the i7 4770K/4790K if you just care about raw CPU performance, but the Iris Pro 6200 Graphics are what have been most compelling as shown in the GPU comparison on the open-source drivers and the integrated graphics comparison.

If you want great integrated graphics backed by a fully open-source driver on Linux, the Core i7 5775C is a terrific purchase. If you care more about raw processor performance, Skylake is just a few months away along with the Intel 100 Series chipsets and DDR4 memory. If you're just interested in these Broadwell parts for the graphics, the Core i7 5675C will also feature the same Iris Pro 6200 graphics as does the Broadwell BGA R-series parts.

My only word of caution over purchasing a Core i7 5775C would be over the Linux kernel issue found initially under Ubuntu. As soon as I find out anymore information from Intel or others or I manage to figure out the precise kernel issue causing the panics, I'll be posting updates on Phoronix. Any other questions about Intel Broadwell on Linux can be directed to our forums or @MichaelLarabel on Twitter.
