someone wants to make a picture story of the fermi is comming in december??

what?

someone wants to make a picture story of the fermi is comming in december??

why december?

Wait a couple weeks and make one for "09" with 3 wise men and Fermi in the middle.

Any news/rumours/roadmap of HD57xx equivalent from nVidia?

Well... it looks like nVidia and ATi are both having the same problem with TSMC. It seems ALL of their 40nm high performance products are getting a crappy 50% yield.

Nope... AMD/ATi isn't having any problems with yields on their current chips, Cypress yields are slightly lower than expected but still fine, Juniper's are better than expected.

A yield of 50%, esp when on a radically new chip architecture with a considerable die shrinkage, is actually pretty good. It's when yields on first batch runs dip below 20% that you start getting serious concerns about profit margins. Some have rumored Fermis yields to be sub 2%, so 50% would be a huge success story by comparison.

The problem is too much talk is being generated from mere rumors. ATI may be increasing their yield, but fact remains no one has 5870s in stock, and if their yields initially were so much better than Nvidia's as implied, that would not be the case. Some seem quick to defend ATI's ability to increase yield, but not Nvidia. Product development/improvement works both ways gentlemen.

Nvidia is NOT getting 50% yields...
I don't think that you guys are understanding what is going on, yields |= capacity. Just because yields are improving doesn't mean they can get more wafers from TSMC. The reason for the shortage is the fact that TSMC was suppose to increase AMD/ATi's capacity from thousands of units per week to 10k units per week(units |= wafers). This was suppose to happen before Q4 and was delayed and delayed for some unknown reason and then the reason that TSMC gave didn't add up.

ummm.. no.

Yield is chips without defects that make unusable. Different circuits have different defect susceptibility. Bigger chips are more likely to have defects.

If your quote was true, and AMD is getting 50% yield on HD58xx, and nVidia is getting 50% on their tiny GT220 DX10.1 40nm chips, then nVidia might as well give up. A 10x bigger complex chip would have dismal pathetic yields like under 1%.

Delay wise, AMD had A2 taped out like June, 4 months before launch. nVidia just taped out Fermi A2, and rumours A3 needed to fix bugs. So we're hoping for March.

AMD had A2 silicon? Where?

why december?

Nothing until late Q2/Q3 '10.
No G300 derivatives have been tapedout yet.

Done.

just as well change it to Jan, Feb... just to have it ready.
