Horsepower is an actual measurement. It can be calculated using real data. QuantiSpeed is not, so it has nothing to do with horsepower. Re: "AMD's model numbers are a much, much, more accurate indicator of performance than flacid P4 mhz." No, Dan. They are quite a bit less accurate. The only thing that makes them "look" accurate is the fact that AMD has chosen values that are flattering when compared to a similar megahertz Pentium 4. As long as AMD continues to chose values that compare favorably in that matter, then they will continue to "look" accurate. However, the number of benchmarks that agree with AMD's performance story is becoming smaller and smaller, yet their choice for model numbering hasn't changed. It is still ((frequency-333MHz) * 3/2) - a very consistent formula that is the basis for The Aberdeen Group's argument. Such formulas are not based on data. There is no way that this kind of data falls into consistent mathematical equations. Benchmarking is complex, and controversial, and yet AMD is trying to come up with a single number that is only an average of certain tests of their choosing. There is nothing scientific about it. I know that the only reason why you like QuantiSpeed is because of your favoritism with AMD. It does wonders for their ASPs, and gives the market perception that their chips are competitive with Intel's. But just like PR ratings, QuantiSpeed is based on arbitrary values, and that carries with it a level of deception - and arguing that model number deception is ok because Intel's megahertz is also deceptive, is not a good argument. Deception is deception, and AMD has left one form of it in favor for another - only this time, there is no hard data to back it up. wbmw
