PB, Re:"That's THEWATSONYOUTH, not me. I do find his analysis very interesting though, and am in the process of trying to verify its veracity. I just saying that 450MHz is, well, 450 MHz on .18, never mind the vaunted Cu?" Seems to me you are posting a bunch of FUD here, i am sure elmer is impressed. The implication seems to be that because the G4 only runs at 450Mhz at 0.18/Cu that somehow implies problems for Athlon. As you are well aware the architecture playa a big role as well. For instance the HP81500(???) runs at lower Mhz than PIII but has much higher performamce. However a more interesting metric would be to see where the PPC was at 0.25 and compare with the new 0.18 devices. The G4's are running approx 50% faster than their 0.25 bretheren. So you might figure out that for the Athlon architecture 1 Ghz should be quite reasonable with the 0.18/cu process as they achieve 650Mhz with 0.25 micron. But I expect you will post more FUD now. regards, Kash

Petz, < You continue to spread this lie about the G4 being a 0.18µ CPU, even when Motorola flatly contradicts you. Your reasoning is based on transistor density, but you vastly underestimate the increase in density due to local interconnect.> P.B.. <That's THEWATSONYOUTH, not me. I do find his analysis very interesting though, and am in the process of trying to verify its veracity. I just saying that 450MHz is, well, 450 MHz on .18, never mind the vaunted Cu?> I think what I said was I believe the Apple G4's are actually from a .25um GROUNDRULE process and NOT .18um groundrules as the press release would have you think. The press release says a .18um (.15um L effective) I believe they are referring to the gate level only and the groundrule generation is actually .25um. - 4 reasons 1) .15um L effective is way too large for .18um groundrules. 2) 450MHz is way too low for .18um groundrules. 3) 83mm2 is too large for G4 in .18um groundrules (G3 without AltiVec was 40mm2 in .25um groundrules) 4) Motorola is generally behind in introducing advanced generations - not ahead. However, at .25um groundrules, all the numbers fit. THE WATSONYOUTH
