Ah.. the memory capacity. It strikes me as odd that the max memory capacity of the G5
top end is 8 GB. Unless I'm completely misunderstanding, 64 bit addressing would imply
2^61 or so memory capacity (taking into account 2^3 bits per Byte if one needs to), not
just an incremental improvement of the G4 32-bit memory limitations. I'm sure it's more
complex than this, and some other limitation applies, but there seems to be the possibility
of way more memory than a mere 4x improvement over the previous generation.
I don't think the address is the full width ...
32 bits is 2^32 = (2^2)(2^10)^3 = 4 gig
64 bits would be (2^32)^2 = the square of that number.
