Intel Core i5 6600K Skylake Linux CPU Benchmarks

Well, those are the initial results of the Core i5 6600K Skylake processor tested on Linux under Fedora 22 with the 4.2 kernel and GCC 5.1.1. Overall the performance appears quite admirable with this Core i5 processor in many cases outperforming the Core i7 CPUs of previous generations when the tests are all open-source and built from source for each of the processors. The strong performance of the Core i5 6600K Linux combined with the good HD Graphics 530 open-source performance on Linux makes the Core i5 6600K quite attractive for new systems.

Since the Skylake launch earlier this month, the CPU availability has improved and you can now find the Core i5 6600K in-stock at for $240 USD. Stay tuned for more Linux tests of the Core i5 6600K in the days ahead on Phoronix and will hopefully soon be followed by Core i7 6700K results. Once again, if you appreciate this testing, be sure to subscribe to Phoronix Premium so that more of these benchmarks and hardware purchases may follow. I'll also be running some LLVM Clang vs. GCC compiler tests, more HD Graphics 530 Mesa tests, and more.

If you want to compare your own Linux system's performance to our results side-by-side, it's easy to do so in an automated manner by installing the open-source Phoronix Test Suite and simply running CFLAGS="-O3 -march=native" CXXFLAGS="-O3 -march=native" phoronix-test-suite benchmark 1508233-HA-INTELSKYL16.
