64bit doesn't specifically make it "more advanced." 64bit CPU's just support for a larger memory addressing space then 32bit CPU's, beyond the 4GB limit of 32bit addresses.
Surely it is more than mere memory addressing, a logic problem which has existed since the original 8088 (and perhaps the 4040), it is extra instructions and a re-write of some existing instructions ?
