Earlier this week I began my Intel Skylake Linux benchmarking by posting some initial results from the HD Graphics 530, the new Intel "Gen9" graphics. While more Intel Linux HD Graphics 530 results are on the way, completed for this weekend are the initial CPU benchmark results comparing the Core i5 6600K to various other Intel Haswell/Broadwell processors as well as some AMD APUs and CPUs.

This article is offering a first glimpse at the Core i5 6600K performance under Linux. All the tests in this article were done from Fedora 22 x86_64 with all available stable release updates plus the Linux 4.2 Git kernel from the Rawhide NoDebug kernel repository. The results are just looking at the CPU performance today and all of the tests were built from source using Fedora 22's GCC 5.1.1 compiler. Most of the tests honored the CFLAGS/CXXFLAGS of "-O3 -march=native" as indicated on the graphs on the following pages.
