blauboad, Elmer, that is the key question - what is the real wafer capacity of Dresden? Way back when AMD was running Fabs 25 & 30 for processors, there was a working assumption that all of Dresden would be available for production. Some guesses were made as to the total wafer start capability, and I think that is where Elmer gets his start.

However, now that Fab 30 is the only processor fab, AMD has to keep sections of it down for new process & product development and deployment. "Full capacity" is relative to the space which can be devoted to mass production.

No one has been able to come up with a confident number for the number of wafer starts one can expect from Fab 30 since. Therein lies the problem.

blauboad -

Ok, but I meant where are you getting these numbers to plug in. Die size is about the only thing we know for sure, and even there we don't know the product mix of different die with much certainty. How do you estimate the wafer capacity of Dresden?

Dresden's wafer capacity is about 5500 wafers per week. AMD has stated that a number of times.

Find Athlon's die size, I'm sure you can find it with a google search and plug it in here:

As for defect density, use .25/cm2. That's world class and the only thing you'll have to take my word for. Anything higher is easier to achieve. Anything lower is speculative on your part. There is no public data to show that anyone is below this point on complex logic at this time. When we come to SOI we don't have a good baseline to use to predict.
