Dan, Re: "You're wrong. (see, I can make unqualified, unsupported blanket statements too, as long as that's the way you want to structure the discussion)"

The problem is that nearly all of your statements are unqualified, unsupported blanket statements. It gets difficult to keep up with your outrageous claims and silly comparisons, and eventually people get tired out. It's not that they finally agree with you, but rather that they decide they've spent enough time arguing with you. I've about reached that spot for today.

The only thing I will dignify is your lame attempt to compare the SOI advantage with Motorola between the G4 and G5. As I've said before, the G5 has a longer pipeline, is made on a smaller manufacturing process, and is a different design than the G4. It still hasn't reached 1.6GHz, but assuming Apple's assertions are true, you can't claim any bit of benefit to SOI, since there is not a single way to do an apples to apples comparison.

Is there a G4 processor that will use SOI? Because that may be a better comparison.

Is there a processor on .13u bulk si that will go to SOI before AMD comes out with Barton? That may lend some credibility to your claim.

But saying that a G4 processor with 4-5 pipeline stages on .18u and 400MHz versus a G5 processor on .13u with 10 pipeline stages and 1.6GHz can owe a lot to SOI for the frequency advantage is silly. Most or all of the frequency could have come from the .13u manufacturing, from the extra pipeline stages, or from the redesign. Could Motorola have reached 1.6GHz without SOI? Quite possibly, though we may never know.

But like I also said, 1.6GHz still doesn't outpace the Athlon, which can get that fast (according to AMD) on .18u bulk si. That's despite the G5 having the same number of critical pipeline stages as the Athlon. So why can't SOI (not to mention .13u manufacturing) get it any faster than that? Is it because perhaps SOI isn't all it's cracked up to be? I'd say that more evidence seems to suggest that SOI is a flop, than any sort of saving grace.
