since AMD's K6/K6-2 has so many more FET's than Intel's PII then why do
benchmarks show the PII to outperform the K6 at the same speed ??


Yousef,

Did PII beat K6 on all benchmarks or only the ones you highlighted? Celeron which is also PII would not even come close to 0.35um K6. Yes, the older generation of AMD slow process beats PII. If Celeron 266 is slower than P5MMX 233 and K6-200, this means K6-233 beats Celeron 300 and even 333. So what was that AMD's 0.25um equals to Intel's 0.35? I think it is the orther way around.

FYI, I have seen the cross section of PII 333, the gate length is 0.181 (0.25um process if you don't know by now)if my measurement is correct. As far as I know, K6, M2, and C6 are not yet there and achieved 300+. What would the speed be when they get there? So the speed gaps between Intel and compeitors are only the luxury of expensive tools and capacities that Intel has.

Who is the next? AMD?

Per Briefing.com

National Semiconductor (NSM) 20 1/2 -5/16: manufacturer of analog intensive, mixed signal and other integrated circuits is warning that it expects to record a loss in Q4 and Q1 due to inventory correction and product transition; sees Q4 revenues declining by as much as 20% below year-ago level of $574.1 mln; according to First Call, NSM was projected to lose $0.19 in Q4, vs year-ago profit of $0.36 a share....

Re: "then why do benchmarks show the PII to outperform the K6 at the same speed ??"

Could it have anything to do with the PII's L2 cache?

Yousef, if you disable L2 cache on the K6 and the PII and run the benchmarks, can you guess which chip is faster as a given clock speed?

Re. Why do benchmarks show the PII consistently outperform K6 at same speed ?
Yousef , a comparison of Celeron and K6 at same speed will show quite the opposite as K6 - 200 roughly equates to Celeron 266 in integer performance . The answer to your question then is the L2 cache and not the processor core .
