Or they just found out that Windows process scheduler is still broken beyond repair. If you look at the benchmarks on GNU/Linux performance is all there. For example see Phoronix benchmark

I know the article says what it is, I know it’s wrong, I know it’s irrelevant…
But I can’t read “SMT” as anything other as Shin Megami Tensei.

so, basically, the os isn’t tuned for the new chips yet.
the 2nd threads on smt-enabled cores are supposed to get hit last.

It’s an easy fix, sure.
But there are 3 manufacturers for them to schedule for. It should be ready way before anything ships.

There should be no need for tuning, tweaking, or optimizing on functionality this basic.
If you ask the processor, it will spit out a graph like this telling you what threads/cores share resources, all the way up to (on large or server platforms) some RAM or PCIe slots being closer to certain groups of cores.

For values of “new chips” that include 20 year old ones. Foster was released 2001, the chips were single-core but you could have up to eight on a board so it’s still multi-core SMT. First on-die multi-core SMT seemed to have been Paxville, 2005.
