The advantage of bitboards comes from greater data density. IE on a 64 bit machine, we use the entire 64 bits that the processor efficiently moves around. Non bitboard programs don't have values that require 64 bits, so that the processor wastes a lot of time fiddling with 64 bit registers with very small values in them. So on a 64 bit machine, bitboards make a lot of sense. On 32 bit machines, there is no real advantage to them, they are probably no slower nor any faster, than a non-bitboard program... But 32 bit machines are on the way out...
