BMW Re..Where do you see this? I don't even think AMD has done Athlon XP vs Northwood comparisons. <<<<< Aren't you nitpicking a little here. AFAIK, the original Quantispeed was conservative in order to reflect accurately the changes going from P4 to NW. But if you insist, "one AMD Quantispeed = 1 P4 mhz" ; and future Quantispeed ratings will change to reflect accurately the ratio between current IPC's. Seems like whomever is in charge of QuantiSpeed marketing isn't doing a very good job. <<<<<<<< Why do you say that? AMD is making out very well with their Quantispeed rating. And as the CPU's change, the rating is changed to reflect the current ratio. As long as AMD stays somewhat consistent with upgrading benchmarks, to reflect current conditions; Quantispeed should remain viable. However, the former, in order to have any backing by the industry, ought to have something more empirical, don't you think?<<<<<< You seem to be interchanging TPI with Quantispeed. TPI, the performace indicator of the whole computer should have a baseline to go by. Quantispeed is a ratio which reflects the ratio in IPC differentials of just the cpus; and should change as the ratio changes. I think the majority of consumers are pretty ignorant of these things, but that's not a put-down. Well, the consumers seem to have gotten the AMD's message better than one would expect. AMD's sessage is that different CPU's deserve different ratings based on their respective IPC and mhz. You can bet that Hammer will really reinforce that theory, if Hammer's IPC goes up by another 30% over NW. So why cry over the demise of the mhz myth. It has seen its day and its time to say bye-bye. Of course, and I agree. Megahertz, though, is based on the frequency of the clock inside a microprocessor. <<<<<<< Yes, and that is AMD's key point. Mhz is just the performance of a certain processor based upon frequency; however it doesn't even reflect accurately the performance of all processors by one manufacturer at a certain mhz, much less the performance of cpu's by different man. That is the problem with it.
