Comparative benchmarks between AMD Ryzen 9 3900X systems running Windows 10 1903 and Ubuntu 18.04.2 LTS show that Microsoft's work in optimizing the OS for MCM CPUs such as Ryzen has paid off. Although Linux does have an overall lead, the scheduler improvements in the latest Windows version have managed to narrow the performance gap significantly.

You didnt source phoronix you ripped off his hard work!!

Huh? Phoronix was mentioned twice in the main news and linked in the source. Thanks for taking the time to read it fully, though.
Cheers!
The Windows scheduler still sucks for AMD Threadripper though. Google "linux windows threadwripper benchmark". And that will not be as easy to fix for Microsoft since it has to do with the NUMA architecture of the Threadripper. Linux has supported NUMA for ages.

Windows Server already supports NUMA nodes. I think MS would have implemented some of those functionality in client versions. Anyways, higher core counts are here to stay and devs have to optimize their code to take advantage of them. :)
There are better performance optimized Linux distributions than Ubuntu. If you take Clear OS Linux, supported by Intel itself for example, it shows 6%-10% faster performance that Ubuntu.
Now, multiple that factor with the advantage of Ubuntu over Windows and the total equals Clear OS Linux 14%-18% better performance over Windows!

That possibility can be evaluated once OEMs ship newer microcode that allows a wider Linux compatibility. Kernel 5.x that most recent distros use apparently has some problems in booting Zen2. However, it apparently works fine if you use the same kernel for Ubuntu 18.04.
