Hi all-
I released new PO (play-only) compiles
which seem to be significantly faster
...more than 10% on my system
Intel® Core™ i9-9900K Processor
Bench was run just once, not averaged after several runs, so these are just estimates:
I hope they prove fast on other systems as well...
PS they have not been widely tested
Wow, fast indeed, 15% or so faster than Nodchip compiles with BMI2. Now at short time control, SV nets with this compile are about 90 Elo points stronger than SF_dev.

Thanks!
At standard chess yes probably, but these NNUE versions are substantially weaker than standard Stockfish at chess960 according to some limited tests I ran. Would be useful if someone else could confirm that.

In Chess variants I checked, NNUE was always weaker than standard SF_dev, I am not surprised it's weaker in Chess960. But for every variant one can train a new network, which can be significantly stronger than SF_dev, as SF_dev was not specifically designed for the variant.
also, see original nodchhip repository (issues and PRs)
PS nodchip's compiles are not created via PGO...using it gives a nice boost
I think the binary can be even faster...
I expect the 1st official SF release to scream, those guys are really good at getting every tiny bit of speed out

I got +39 elo over recent SF (July 6) on 7 threads at 0.5' + 0.5" after 170 games. Maybe gains are less with more threads?

What is the draw rate in your case? Aside 1 thread ultra-fast TC, I am using unbalanced openings too, so my draw rate is about 35%. The discrepancy comes from these very different conditions and from just 170 games.

I only got +20 elo playing 32 threads at 3m+2s on a 2950x at 4.1 Ghz. Still outstanding.
