Kabylake vs Skylake for compute on Linux — Linpack on Ubuntu 1610

OK, Intel Core-i7 7th gen Kabylake is out. Of course the first thing I want to do is drop a Core i7 7700K in a new Z270 based motherboard, install Linux and run a Linpack benchmark. You know, GFLOP/s and all that. We installed Ubuntu 1610 with a recent release of Intel MKL and fired up a few Linpack job runs. Read on for the not-so dramatic results.
