Since the PIII (not quite sure) intel introduced Extended paging. Since then these chips have 36 address pins. So it can use 2^36 bytes memory. But i think this whole discussion is useless because we are comparing diffrent architectures. I've no experience with sparcs but i guess it has it's advantages for some applications over a x86. But the other way arround it's also true. Intel creates performance by pushing the clock to the limit, sun creates performance by using it's head and making the architecture more performant. If they could speed up the clockspeed to the same level as intel does, i think it can easily outperform intel. But intel has one big advantage. They are cheap.
