paul,

have you got your Segway?

i'm surprised you're are online. probably not with @home?

Hence, the available information from AMD - coupled with just a few common sense assumptions - results in the conclusion that AMD is yielding only 27% of the AthWiper/DudWrong die on each processed CPU wafer being functional and meeting their specifications for shipments to customers. This is an APPALLINGLY LOW number and accounts for AMD losing money despite AMD having a big die size advantage over Intel - whereas Intel's IABG division was quite profitable this past quarter - Q3, 2001.

Exactly what I keep saying. The numbers are inescapeable and speak for themselves. It's simple... AMD's yields stink.

BTW: You need to allow another ~5% for assemble/Test fallout, but what's a couple a die amongst friends?

pAUL, Yousef

re:"AMD's Die Yields are only 27%"

You forgot the copper contamination at Dresden and that AMD can't make anything run faster than 300Mhz.

Make it so,

AMD's Die Yields are only 27%

Paul, much as we hate the expression "you outdid yourself", on that one, you did!

Re: Computing an "average die size" is done simply by taking 50% of 104 + 40% of 120 and 10% of 129 (0.5*104 + 0.4*120 + 0.1*129) = 112.9 sq. mm. "in the aggregate" AMD executives love to use this expression - "in the aggregate" !!

Great attention to detail throughout the post. A lazier guy like me would have done a SWAG on overall average die size instead of calculating it across all three chip types.

Re: This is an APPALLINGLY LOW number and accounts for AMD losing money despite AMD having a big die size advantage over Intel - whereas Intel's IABG division was quite profitable this past quarter - Q3, 2001.

AMD generally blamed ASPs for the quarterly loss, if I recall. Trying to recall Hector's words re yields during the Q3 end CC and their recent webcast. Nothing comes to mind right away, but I think they've been claiming good yields all along. ?!?!

Paul, your post sounds just like Dan's - filled with assumptions and passed off like a fact. I was almost on the floor laughing before I realized that you might be serious. Are you, or is this just one big satire on Dan3?

In the case of the former, I will have to take your analysis with a grain of salt; otherwise, this might be one of the funniest things I've ever read.

Paul, I've got a little nitpick here. You called AMD's fabs "MegaFlop 30" and "MegaFlop 35." I don't know where you got the numbers from, because AMD calls them Fab 25 and Fab 30.

In any case, either AMD is running their fabs at capacity, which would suggest terrible yields, or AMD isn't (process transitions and whatever), which makes one wonder why they were looking for foundry capacity.

cool post Paul.
So that's a deja-vu in AMD's land, no? wasn't the poor yields that killed them in the years gone by? I kind of remember "sharp tooth" ?

Isn't this just another example of what Mary was saying that Dan did? Confusing lurkers who may be unaware that Paul is being facetious?

I agree with Mary on this point. Dan, please back up your numbers.

Paul,

Question, how long does it take to fully process a wafer for the litograghy, etching, cutting and finally testing the dice?

3 months? 6 months?
