64 bitboard and more registers are logical reasons but it concerns x86 only.

No there is a distinction in what Ronald is saying that you seem to have missed
=> yes x86-64 is faster than x86 in general, and that is an *exception* (more registers)
=> the extensive use of bitboards makes chess programs faster on 64 bit regardless of the architecture. in my engine the difference is like day and night, 64 bit is almost twice faster, and it's normal given the amount of bitboard operations.
