I also had to guess between the 3400+s - and also guessed right :) Comparing 256 MB v 512 MB is a bit hard to understand though. Rotated bitboard lookup tables alone require 190K. Many entries of course are extremely rare but I would think that these tables would more or less occupy 190 K of the cache. Vas
