Elmer - Re: "the only way AMD can claim world class yields and claim capacity constraints (and not be liars) is if they are only allocating about 30% of their fab capacity to processors. "

Sure - and AMD's major business (other than the measley CPUs) - consuming the other 70% of fab capacity - is what - Op Amps?


I'm not the one to defend this one. I'll leave that to the Hemdroids. But the numbers are correct. Based on the normal yield from a typical foundry, a device with the size of Athlon should yield about 140-145 DPW. So my spreadsheet says AMD is only allocating ~40% (I stand corrected on my 30% number) of their fab capacity if they are enjoying industry standard yields. Intel yields higher than this but I am not at liberty to say how much higher. I will say that everyone I have ever talked to who has contracted wafers from Intel and any other foundry has said 100% of the time that Intel wafers yield significantly higher than any other fab and my last experience was comparing wafers from IBM.
