<Let me ask you this. Everything else equal which core will scale better the K7 pr P-III? If the K7 does then AMD will have achieved it's most important goal. Leading the MHz race. Add a great FPU and they will have taken both Intels advantages.>

I really don't know which core will scale better. The K7 has a 10-stage pipeline, while the Pentium III has a 12 to 14-stage pipeline. Judging from this alone, both cores will scale similarly. (Note: Just because AMD was able to get to 475 MHz with a 5-stage pipeline doesn't mean anything. If Intel really wanted to, they could have pushed the 6-stage Pentium MMX to similar speeds.)

Of course, there are other factors behind MHz scalability besides long pipelines. All I know is that there isn't anything in the K7 foils that convinced me that the K7 is inherently much more scalable in MHz than the P6.
