It is very application dependent. The AMD64 architecture has more
registers, and the registers are wider, so for some applications you
can get significant speedup. On the other hand, you also get wider
pointers and such, and those consume more cache and memory. You should
benchmark if you're doing any sort of performance critical application
to figure out which is better for your app.
