Re: "It seems that all you know about IC manufacturing
is the defect density. "

Ali... still as confused as ever. You are the one who said AMD had low yields, not me. Yields are not just related to defect density, they are a function of defect density. Here's what you said:

"Yes, formally it looks like "manufacturing problem" with low yields. But not because AMD transistors were weaker as you believes, but because the 4-stage design was always at huge disadvantage for manufacturability as compared to P6 counterpart."

I suggest you go down to the local Junior College and ask one of the instructors what is the difference between yield and binsplit because it looks like the problem you are trying to describe is simple binsplit. So under those conditions AMD may not have had a manufacturing problem after all but simply couldn't sell all those slow parts. Don't try to make it any more complicated than that.
