This is only true if you happen to be dealing with integers larger than 32 bits (rarely in most of today's code). The real performance benefit of x64 has more to do with a larger number of general-purpose registers. More registers allow (but don't guarantee) programs to spend less time accessing main memory, thus gaining some speed.

Yes, I knew about the registers. I guess I overestimated the number of applications that involve large number computations.

Or perhaps I underestimated them...
