Petz, You continue to display how little you really know.

<1. Increasing Vcc by 0.1 volts could not possibly affect the speed bin for that many processors.>

Increasing the VCC by 100mv could make all the difference in the world. Sometimes a process is that close to the line.

<How is it that Jerry and AMD Investor Relations predicted exactly when the yield problem would be solved? >

Who says it's solved? All we have is your word for it and frankly, that's as good a guarantee as one could ask for that it isn't.

<The premise that a K6-233 at 3.3 volts cooled according to the specifications shown in the spec is less reliable than a K6-233 at 3.2 volts is fallacious. >

Petz, this isn't a heat thing. This is a blown gate oxide thing.
Voltage is the operative factor, not just heat. Why didn't AMD sell a 3.3V K6 from the start? They could have boosted their yields from the beginning. They chose not to. Why? Because of the obvious reliability implications, thats why. Why did they change their minds? Did they increase the gate oxide thickness so that it could withstand higher voltage? No! That would slow down the switching speed. Yet they now sell a 233mhz 3.3V K6 when they refused to in the past. Why????
Desperation is the only rational explanation. Nothing else fits.
Why doesn't Intel boost the VCC and sell higher speed parts, just like AMD is doing? Because the parts would blow up, that's why. Intel isn't desperate. Intel isn't postings red ink. Intel isn't going bankrupt.
That's why.
