Xbox 360 still ran in 32bit mode with the exception of the hypervisor. No use of 64bit pointers on a system with a max of 1GB of RAM other than just wasting cache space, and there's no real other benefit tacked on like you see in other 64-bit archs.

Thanks I didn't know this. I just looked up since when PowerPc 64-bit is a think.

Ah. In that case the PowerPC 620 was a 64 bit design from the late nineties.
