Thanks. > > Joe Clarke If I can believe what I have read on the Tom's Hardware web site, the Pentium III is just a PII core with the SIMS instruction set added (which is similar to the 3DNow instruction set on the AMD K6-2 processors). You will see absolutely no performance improvement from a PIII over a PII unless any software you're using specifically supports SIMS. The upcoming K6-3 has me waiting anxiously, however, since it should have a noticeable performance improvement over the K6-2 because of the on-chip L2 cache (256k) running at core clock speed (it is still a K6-2 core, AFAIK). The K6-2 has already given all of the Intel processors a good run for the money, and I'm rather hoping the K6-3 will provide no reason to buy a PII or PIII. :-) -- Chris Dillon - cdillon@wolves.k12.mo.us - cdillon@inter-linc.net /* FreeBSD: The fastest and most stable server OS on the planet.
