They were better than 6502's for So by your definition, a PC with SDRAM is 64-bit, whereas a new Pentium III with Rambus memory is 16-bit. Or maybe 256-bit, due to the interface to the L2 cache?

Even if they are roughly equivalent in terms of MIPS, the 68k can still address much more memory, and it's much easier to do this. I bet this is one of the reasons the Genesis whomped the Nintendo. -Tom
