DRK 56 has got an impressive 33,89% against Deep Rybka4, Fire 1.31 and Naum 4.2, with such a big handicap in cores. (Current tests -going on- are good but not that excellent).
And:
Same rivals and time control in a 8 threads computer.

With this huge (cores and w32) handicap DRK56 has got an excellent 28,89% score against Deep Rybka4, Fire 1.31 and Naum 4.2
On the other hand, look at this new, powerful MishasMauler12T. Perhaps the best engine today in the world using one core. (Not enough games, I know, but... please, rely on the instinct of this old tester).
