Can an Intel Celeron CPU overclock just as well as a P4 if they both run...

...on the Prescott core?

Nope. The performance is different because of the different architecture (even if shares same core). Example is the different quantity of L2 cache memory...

You can overclock celeron cpu same as P4 but performance wold differ a lot as they have different L2 cache.

Hope this helps.
