Thanks for testing. But what a strange result for Minic ! Were both version tested on the same hardware ? Are you sure about the settings ? The results look like you tested HCE instead of embedded net.

Oh I just realized your hardware is AVX and not AVX2, that may be the clue.

I tested this version with the embedded net "nidicolous nighthawk".

info string This is Minic version 3.09 (NNUE available)
info string Info 2021-08-20 08:57:24-802: Loading NNUE net embedded

Did I do something wrong?

[fastgm]

Yes, hardware is AVX.
Does AVX2 make such a big difference?

[xr_a_y]

Ok the nehalem build is only SSE4.2, with your xeon E5-2670 you probably can use the sandybridge one.

Yes big difference ! between the SSE4.2, the AVX and the AVX2 built for NNUE engine.

Yes big difference ! between the SSE4.2, the AVX and the AVX2 built for NNUE engine.

Well, next I'll test this version:
minic_3.12_mingw_x64_sandybridge.exe

Then at least we see this difference.

[xr_a_y]

Well you will see a difference between SSE4.2 and AVX but at very short TC (5s+0.1) AVX2 makes a huge difference (only hand optimized code in Minic)
