Joe, I do not see any reason why anyone should continue to
converse with this guy. He was caught red-handed in making up
disinformation about Intel readiness for 3-GHz parts,
and even have confessed in making the baloney:

I suggest, if Mani is not going to ban the liar
automatically, to boycott him, and do not reply to
his baits.

Regards,

Jozef,

Re: "Again, what are AMD's yields, and if they are not world class, what is world class?"

"World Class" defect density at .18um (and soon .13um) is .2 -> .25
defects per cm^2 . This then can be used to calculate a yield that
depends on the die size. I posted on this subject a week or so ago -->

Message 17244504

So Jozef, for a 100mm^2 die ... "World Class" yield would be about
78% -> 80%.

Make It So,
Yousef

The term "World Class Yields" doesn't really mean anything. It's another ill defined term AMD tosses out to confuse analysts and Droids. They only measure of how well a fab is running is defect density. Yousef used the value of .25df/mm2 as a good reference point for "World Class" and I have seen IBM run very close to this number. No comment on where Intel runs. At .25df/mm2 AMD would be able to produce >150 good Palominos per wafer. At that rate AMD would have only used about 2200 wafers from Fab30 to produce 4.3 million Athlons in Q4. Only 44% of the fab capacity. With higher DD the fab utilization would have been higher but then they wouldn't have "World Class Yields" like Jerry claimed and we all know Jerry never lies.
