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

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

Pity not for Xeon X5670.

Thats compiled with march=znver1 as the target architecture.

Awesome binary! On my Ryzen 3900 this one is more than +8% faster than popcount-compile and popcount-see41 compile !
I will use this one (of course) for my testrun. Testrun starts tomorrow, should end on monday.

Its not clear to me what target would be chosen for an Xeon X5670. I cannot find any good documentation.

However, it appears that the Xeon x5670s have the same instructions I covered in the SEE4.1 build. So thats what you would want.

Pity it doesn't, Andrew. Westmere's the nearest to my Xeon, I think.
Does a certain nnue- net have to be in installation folder?

This is not an NNUE; it has nothing to do with SF or Leela or A0.
Its just an NN thats hard coded into the evaluation for Pawns.
There is no setup -- it will work as is.

I see and I thought so anyhow.
Yet the SSE4.1-popcnt compile doesn't work in console (Win7x64 Pro closes the window with error- message).

Then just use the regular popcnt version. The NN is minimal. SSE won't do much.

This one works well.
About 3/4 the n/s of Ethereal 12.50 popcnt, which is quite good compared to other NNUE- binaries I know for my CPU.

Crashes in Fritz- GUI when number of MultiPV- lines is changed, ("error in the engine") but starts running again at once with stop-start by GUI.

Thanks again regards

75% the original speed is slow. The slowdown is < 10%, so I'm not sure what you are seeing.

As for Fritz, I don't have or use Fritz GUI. Are you trying to change MultiPV during a search? Thats not allowable.

As a matter of fact it freezes with longer pondering now and then too without any GUI- command, just out of curiosity, how to change MultiPV if search isn't running? (in any GUI, ok, Arena has the feature to give in number of primary lines in engine- options, didn't try that till now.)

Nevermind, all's good for me so far regards
