But for my program, a PII/200 is 1/2 the speed of a PII/400, almost exactly. But the PII/400 is not 2x the P6/200 because the P6's cache is exactly as fast as the PII/400's cache. > >>And note that these are *real* results from data obtained from 450mhz xeon >>results, and comparing to my P6/200 with everything identical. > >Yes, yes, you found a Xeon. Fine. I'm about 50 feet away from 200 of them. > >Cheers, >Tom I didn't find "a xeon". I found a *lab full*. Crafty's the latest addition to specint98, which gets me lots of benchmark results I can't reveal until the chips are released.
