Cache Differences
It's true
that the core of the Celeron 2 is the same as in the Pentium 3, but what about
the L2 cache? Similar to the C1 and Pentium 2 core, not only is the cache
less, but it's physically different. Using H. Oda's nifty CPUID program,
we can see the differences between the C1 and C2.
