When looking at the geometric mean of all the benchmarks carried out on Ubuntu 18.04.2 LTS and Windows 10 1903 with this AMD Ryzen 9 3900X, Ubuntu Linux led by approximately 8%. While the test set is slightly different, overall these results show Windows 10 being slightly more competitive than we have seen out of past Windows vs. Linux AMD benchmark comparisons, likely due to the improvements made in 1903 and AMD's new Zen 2 drivers such as the scheduler fixes/optimizations. But overall it's nice to see Linux is still faster and winning a majority of the tests.
