There _is_ more. It also has 96kb L2 cache, and most likely at least 1MB of L3 cache. The PIII only has 32kb L1 and 256K L2. > >for diep a 633Mhz 21164 is as slow as a PII at 380Mhz. Not for me... the 21164 is still faster clock for clock. Not as fast as the 264, but faster. > >So that's a PIII at 300Mhz. > >Only the 21264 is interesting, but only if it's clocked to >a reasonable height and dual.

A single 21264 _is_ faster than dual PIII's at the same clock rate, and that doesn't count the fact that a single is more efficient than a dual on top of that. Tim's Dual 21264 was faster than my quad 700, for reference. And his dual was 600mhz.
