Celeron only has 128K L2 cache, 1.5G P4 has 256K.  the performance
difference can be huge between them, as P4 is heavily depending on L2 cache.
Just to give you an idea: a popular hardware site overclocked 2G celeron to
3G (which is much faster than a "real 3G Celeron", because they overclocked
the FSB), and in benchmark, a P4 1.6G (512K L2 cache) beat the 3G celeron
badly.  I think later Celeron will have 256K L2 cache.  But, Celeron is the
worst CPU you could ever buy in term of performance, also is the worst in
price/performance.  If you consider a P4 system, don't ever think of a
Celeron, it is not worth your hard earned money.  Unless you have special
needs that proper P4 can't offer (eg proper P4 is too hot, and you need to
reduce the heat as much as possible, or you are a hardcore Intel fan that
works on a very tight budget).

*Once, I had a PC build that had to change from P4 to celeron because of
heat issue.
