I have a machine with a 400mhz pentium II, and another with a 550mhz pentium III, both running 100mhz bus speeds. I ran the PIII at 400mhz and found it to run within a percent or two of the PII at 400mhz... Looking at the specs, the PIII should be a bit faster as the cache is faster (not in mhz but in clock ticks for a cache miss). In fact, the PIII seems to be built around the celeron-type cache, except it is bigger than the celeron's.
