<Yes, I have confirmation from my coworker in Willamette-ville. I think there are some parts which may run at 750 MHz, but the FPU runs at 1.5 GHz and the integer runs at 3.0 GHz.> This is very interesting. There are three clock domains in the Willamette core: 0.75, 1.5, and 3GHz. The question is which parts are running at 750MHz? The natural guess would be the decoders, which, according to Glenn Hinton, are de-coupled from the main execution loop with the addition of the trace cache. If true this would have very interesting implications on performance on applications with poor locality. Applications causing frequent trace cache faults would run on 1.5GHz Willamette no faster (or slower) than a 750MHz Athlon. I see a big problem for Slick Willy here. Kap
