A 64 bit CPU is possibly faster in terms of integer manipulation. Given a 32 bit CPU and equivalent 64 bit version of the same CPU, with the same pipeline lengths, a 64 bit math operation takes up fewer pipeline stages on the 64 bit CPU (since the operation isn't broken up into 32 bit pieces) which possibly improves things like branch prediction.
