Scores using 4 cores = 137.5 – 102.5 = 57.29%
Segmenting the result by Time Control:
Fixed = 137.0 – 103.0 = 57.08%
Incremental = 147.0 – 93.0 = 61.25%
Global Score: 284.0 – 196.0 = 59.17%
Against Critter 1.6a (3093): 65.00% Houdini 3.0 Pro (3172): 54.69% Komodo 6 (3154): 57.81%
Average ELO of opponents= 3.140
Estimated ELO Performance= 3.204
This is the best score till now in my tests with no Large Pages allowed. SF scores consistently more than 30 Estimated Elo Points above Houdini 3,0 Pro in my latest 3 tests. (1.440 games)
With Large Pages (Ipman's compiles):
Stockfish 111113SL 64 SSE4.2I = 3224
Stockfish 161113SL 64 SSE4.2L = 3203
Average using Large Pages = 3213.5 Estimated Elo Points. (41.5 EEP above Houdini 3.0 Pro)
Without Large Pages:
Stockfish 191113 64 SSE4.2x = 3204 (32 EEP above Houdini 3.0 Pro).
Awesome performance of Stockfish in these last three tests. Congratulations again to Marco and team!.
