Because it works on twice as much data in a single cycle. A 32 bit processor requires two or more instructions to operate on 64 bit values such as those found in Crafty (and other bitmap programs). A 64 bit cpu requires only one instruction. IE it is twice as fast at the same clock frequency for those places where the 64 bit operations are needed...
