SF12 1 core beats easily SF11 4 cores

Post by Jouni »

I don't remember so far direct test. But here's one 1m + 1s level and shortlines openings. 1 th vs 4 th.

Code: Select all

                                
1   Stockfish 12           +38  +18/=75/-7 55.50%   55.5/100
2   Stockfish 11 64 BMI2   -38  +7/=75/-18 44.50%   44.5/100

That is real progress :!: :!: .

I only have 4 cores, so I repeat match giving SF11 also 20% time advantage. Result: exactly same! With these conditions You need 6-8 cores to draw SF12.
