Unfortunately, I don't recall how it goes ... as a server, Intel is > faster, and for graphics processing, AMD is ... or something like that? From what I've read, the extra cache in the PII/III gives you a 5% boost over the Celeron (I'll guess more for some server apps). Intel still sells the Xeon chips, which have a cache twice as big as the PII/III, but I'm not sure the clock has kept pace and it was always overpriced wrt performance. I don't remember which way the Intel/AMD thing goes, but most folks won't notice a 5% difference in speed. Not that anyone asked, but imho the best price/performance x86 machine has always been a dual processor box one or two clock jumps behind the fastest available. You get ~80% more performance for ~5% more cost than a uniprocessor at the fastest speed. I haven't looked recently to see if there are now uniprocessor machines at the low end that can beat the price/performance of the dual-processor setup. - Thomas -- Thomas Lockhart lockhart@alumni.caltech.edu South Pasadena, California
