The Celeron is the name of Intels value line of CPUs. It originally started out as a PII w/ NO L2 cache, performance was dismal at best. So Intel decided to add 128K on die at full speed These chips were fast, and overclocked very well. Next Intel switched the Cleron to a coppermine core, again with 128k of cache and eventually a 100MHz bus.
Many of the Coppermine Celerons were PIIIs w/ half the cache disabled. This helped Intel sell chips who could not be validated as a PIII.
