Awesome , Windows with with above plus -mavx2 please. Thanks!

I'm assuming you have a Ryzen? If not, it should still work I imagine.

Thats compiled with march=znver1 as the target architecture.

Thank you - benches just under 100M nps using all 64 threads on a 3970x

I've actually removed the "NNUE" component of this Pawn+King Network. I was doing incremental updates, I assume similar to how Stockfish was doing it, but with the added caveat that not all moves actually update the Network when only looking at Pawns + Kings.

Turns out that its faster to fully compute the Network, with some bitboard tricks, aided by the near 99%+ Hitrate of the tables on long searches and especially in endgames. The new version, the fully computed version, appears almost 10% faster in pure Pawn+King endgames. Quite a jump.

I've had a possibly stupid thought that it could make sense to count P & K moves during QS; if <=m P/K positions have changed between the QS start and the leaf where static eval is called, then update the net incrementally; if >m, update fully. (The optimal m is probably 1, but I'd test bigger values too because of FOMO It can be 0 when there are few pawns left; I can't believe it's 0 in all cases.)
