RubiChess 1.8 64-bit.........3252 Elo CCRL_40_4
Fire 7.1 64-bit................3335 Elo CCRL_40_4........+83 Elo...handcrafted evaluations
The intermediate result of the direct match............+173 Elo for RubiChess_1.9_NNUE
The gain due to the use of NNUE (SV2257) seems to be around 250 Elo points.
And here is (again :) ) a sample of NNUE evaluation vs. handcrafted evaluation:
A very spectacular match.
