Now we're moving onto some of the Linux non-gaming CPU benchmarks.

First up was the x264 video encoding benchmark. The x264 test is multi-threaded and thus the Ryzen 7 CPUs with their eight cores / sixteen threads pack a punch, but even with the Intel Core i7 CPUs tested with their six cores / twelve threads, they compete in-line with the Ryzen CPUs. Under x264 the Core i7 8086K overclocked result was about equal to the Ryzen 7 2700X.

In the VP9 libvpx video encoding test that doesn't scale quite as well as x264, the Core i7 8086K performance was now well ahead of the Ryzen 7 2700X.

On a performance-per-Watt basis, the stock Core i7 8086K was delivering the best power efficiency but that dropped significantly when all cores were running at 5.0GHz.

The overclock of the i7-8086K also shot up the CPU core temperature, but still was running within an acceptable range and not thermal throttling.

In the single-threaded FLAC/MP3 audio encoding benchmarks, the Intel Coffeelake CPUs were noticeably faster than the AMD Ryzen CPUs due to their greater instructions per clock performance.
