One short answer is that a 32-bit CPU (i386 - Pentium, Athlon, etc.) uses
32-bit addressing, while a 64-bit CPU (x86_64 - Opteron, Itanium, etc.) uses
64-bit addressing -- meaning your OS and applications can address more than 4
GB of memory at one time.

I know that much... my question was specifically about x86_64 and i686
(since I was under the impression that i686 also means a 64-bit
processor).

I imagine i686 covers a much wider range of CPUs, not all of which are 64-bit?
