Re:" the .18u Athlon is currently shipping at 1.67Ghz.
405 on top of that is 2.338 Ghz "

AMD QuantiMath at work?

1.67 GHz + 405 MHz = 2.075 GHz

Maybe just AMD GigaEnvy at work.

Jim, Re: "Your math seems to be good if the PR rating scales linearly."

Actually, I think Constantine was hoping for 2.8GHz in Q4 2002, rather than modelhertz. Of course, I think you are probably right. A model 2800+ Athlon will reign in at 2.2GHz, which is where I predict the Athlon will be at by the end of the year.

The only problem with AMD is that modelhertz are scaling 33% faster than gigahertz, and I don't think the Athlon is getting 33% better scalability than the Pentium 4. Rather, benchmarks seem to show that the Athlon and Pentium 4 scale equally well with megahertz (in other words, whatever improvement a Pentium 4 gets with 10% extra frequency is how much an Athlon gets with 10% extra frequency - not model numbers). In 2002, the Athlon will only be able to meet the speed of the Pentium 4 in terms of model numbers, while in performance the Pentium 4 will be catching up at a rate of 33%.
