The PII has 512k L2 cache, running at "half speed". (Meaning that if you have a 500MHz PII, the L2 cache runs at 250MHz.) The Celeron is exactly like the PII, except it has 128k L2 cache running at full speed. The non-Coppermine PIII is exactly like the PII, except it has Intel's "SSE" instructions. This doesn't really matter, because SSE-optimized programs are few and far between. (Definitely not chess programs, too.) The Coppermine PIII is also exactly like the PII, except it has SSE _and_ 256k of full speed L2 cache. So, only two definite conclusions can be drawn from this: * The non-Coppermine PIII is not faster than the PII (well, almost never) * The Coppermine PIII is faster than the Celeron Other than that, it depends on what programs you're running and how well they're suited to particular cache setups. -Tom
