this gets fun.  AFAIK, there's several generations of Celerons and its 
quite frustrating to tell them apart from purely a clock speed.

The original Celerons were based on cache reduced P2 Deschutes, and 
later P3 Coppermine, these had 66Mhz busses, and used socket 370 (or 
even Slot 1 for the oldest versions).   These had MMX and/or SSE 
depending on the age.

there were Celerons from 2.0 to 2.8Ghz that were 478 pin 400Mhz FSB, and 
P4 "Northwood" generation technology.    I do believe these are  SSE2 
but I'm having trouble finding definitive documentation of this.

there are also Celeron "D" that are Prescott and can be either socket 
478 or LGA775 and run from 2.13 up to 3.33Ghz, using a 533Mhz FSB, these 
have SSE3.


and nowdays, there are celerons that are based on Core....   really 
really confusing.
