Is there something about PP200 that goes beyond the well.. in pentium world the l2 cache is outside the cpu, i think it's nowadays around 7ns fast, and sits on the system bus, that'd be on the 66mhz bus. on pro the l2 is _inside_ the cpu, just think about the technological costs in making the cache inside the cpu, it's also operating with the cpu speed, not the bus speed... i think there will be cacheless pro's out one of these days, not that i'd want one... quad 500mhz with 2048 cache each would be more like it... =)))) and generally pro with 256 cache is about half what pro with 512 cache for most obvious reasons... the cache is the most expensive part of the cpu. and ofcourse, correct if i'm not too right... mickey
