It's not that special.
Let's say the result would be even better = 500000 kn/s using Linux.
We will lose probably 10% to 20% when using Windows (ChessBase or Fritz or...) = Between 400000 kn/s to 450000 kn/s.
The Hyperthreading/Multithreading and elo gain problem was also discussed in another topic.
The kn/s increase from Hyperthreading doesn't translate in much Elo gain, because the number of search threads also doubles, leading to redundant searches that increase NPS, but don't actually contribute anything useful.
See:

Intel CPU with Hyperthreading 60000 kn/s and newest Intel CPU which has no Hyperthreading 20000 kn/s. -66%.
A 45000 kn/s Hyperthreading CPU is probably +5 Elo stronger than a 15000 kn/s Hyperthreading CPU.
A 45000 kn/s Hyperthreading CPU is probably +1 Elo stronger than a 15000 kn/s no Hyperthreading CPU.
The AMD with 450000 kn/s Hyperthreading should be still stronger than a 150000 kn/s no Hyperthreading CPU but probably only +0.1 Elo.
Stockfish 14.1 with the ARM speed up code improvements from Stockfish developers should have between 50000 kn/s to 65000 kn/s on Apple M4 MAX MacBook.
So we can say 150000 kn/s are enough to have a fair fight(nearly same strength) vs the 450000 kn/s from AMD and 150000 kn/s is only 2.3 to 3 times faster than Apples M4 MAX MacBook.
