It seems performance under Linux is significantly better: https://www.phoronix.com/scan.php?page=article&item=amd-linu...

I wonder if this comes down to Linux being more adept at handling "exotic" NUMA configurations compared to (desktop) Windows. Even if the "server" editions of Windows could handle them Microsoft may have left that functionality out of the "desktop" kernels for product segmentation purposes.

There are now Windows server benchmarks available as well (it's just as bad) : https://www.phoronix.com/scan.php?page=article&item=windows-...

The biggest benefit I've found to running a 1950X isn't something I would have expected, but which perhaps I should have. True, it's much faster than my old system for batch processing, but most of the time it's still idle. Even if it's running Chrome flat-out, as far as the 1950X is concerned, that's idle. Because the two NUMA nodes are ~entirely independent, it's capable of running two independent processes at full…

One instance of this might be "running a performance-intensive game fullscreen on one virtual desktop while having a browser open to read strategy guides on another virtual desktop". This is a common use case for me that also seems to be the first place where performance starts to diminish.

That's probably a lot to do with two instances of virtual desktops running, though.
