"From all of these benchmarks, the geometric mean does show that the Windows 10 Enterprise does perform better than Windows 10 Professional on this HEDT processor particularly at 32 cores and above. Going from 16 to 128 threads on Clear Linux was 3.3x the performance with the tested software to Windows 10 Enterprise at 2.7x. At 16 cores, Linux was just 7% faster than Windows 10 Enterprise with these benchmarks but when taking full advantage of the chip at 64 cores + SMT, Linux was 29% faster. Going from 64 to 128 threads with SMT on Linux led to a 15% boost while Windows 10 Enterprise saw just a 7% boost overall. So, yes, for those wishing to take full advantage of the AMD Ryzen Threadripper 3990X, so far Linux is offering much better performance assuming your software is natively supported outside of Windows."
Do people actually make decisions like that? I guess if you're doing some python based data analysis it could make sense.
Now that Linux gaming is somewhat viable, performance is back on the forefront of my mind; it's fun to know that my (first-gen) Threadripper machine runs significantly better when I install Slackware on it instead of Windows.
I think you answered your own question. ;)
Any CPU heavy tasks really. If you can squeeze an extra 20% performance boost over Windows, running Linux would a pragmatic and economical choice.
