The model numbers are totally inconsistent. Based on that info, a P4 Celeron 2.66 is equivalent to an 800 FSB Prescott 3.0 GHz.
What a joke!
Its clear Intel wants to hide their performance because it is no longer competitive.
The Celeron P4 series is VASTLY overrated, the Celeron M series is vastly UNDERRATED, and the Pentium M series is somewhat OVERRATED compared to Prescott.
All we can figure out from these ratings is that if the last 2 digits are about 50, its the fastest chip within that series, but its rating has nothing to do with chips from other series.
