I'm not doubting you, but I would like to have a mental model of roughly why and how 64-bit mode benefits a system. Leaving aside any x86 architecturable hobbling that may be cleaner in the emt64 world, I would have naively assumed that (absent a need to access >4GB of RAM or mmap >4GB of a file) 32-bit would use physically smaller instructions and generally require physically less bandwidth. Presumably these presumptions are wrong or misleading; I'd like to know how.
