i really don't think there is a way to answer this. i'm not an expert
on hardware, but 64bit applies to the CPU, nothing else. a larger
bottom level cache allows the CPU to view/consume more data/bits at
once, and to perform better on precision mathematics like heavy
floating point operations. i don't see it having much-to-any effect
on RAM usage, but again maybe i'm missing something and then someone
will surely correct me :-)

again don't worry about the differences. 64 bit means you don't have
to deal with address space limits/etc.... its the way to go.
