Intel Core i5 8400 Linux Performance

With Coffee Lake marking the end of an era of quad-core designs for Core i5s, the Core i5 8400 with its six cores is able to offer much better performance in the multi-threaded workloads than the previous Kabylake and Skylake Core i5 CPUs. While there wasn't much of a difference going from a Core i5 Haswell to Core i5 Skylake, the difference from the Core i5 7600K to Core i5 8400 is a 45% boost in performance for this embarrassingly parallel benchmark from NASA.

In Rodinia's OpenMP tests, the Core i5 8400 with its hexa-core design even ends up coming out ahead of the Core i7 7700K Kabylake.

Or in the case of HMMer, the Core i5 8400 even beats the Ryzen 7 1800X due to the greater IPC performance of Coffee Lake compared to Zen.

With John The Ripper, the Core i5 8400 is 45% faster than the Core i5 7600K. Unfortunately AMD hadn't sent over any review samples of the Ryzen 5 CPUs for Linux testing at Phoronix for showing precisely how they would compare to the Core i5 Coffee Lake.
