otherwise). So then, if there is no speed advantage, what's the point in even having a 64 bit processor right now?
Addressing large virtual address spaces and / or installing large amounts of physical RAM.
If you don't need one or both of these things, it's just overhead without payback. Although the analogy is going to be a little contrived, its something like

I mean if PCs really ever do need to have more than 4gig of real storage/virtual storage then.. .maybe. But also remember that the processor's instruction set complexity (and performance) play a role (are impacted). I really think that multiple cores is going to be more practical (32 bit) than a wider bus. I would much rather have a quad processor (32 bit) right now than a 64 bit bus... which for the most part I do not need. -- Kind regards, M Harris <>< -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
