Nvidia GT300 yields are under 2%

[Calmatory]

No they didn't. Plenty of silicon chips are as big or bigger than GT200.

Means that GT200 wouldn't be too big? Name me 5 chips bigger than GT200. I will name you 500 chips smaller than GT200 in return.

G300 is smaller than GT200 but larger than GT200b.

Source?

Larrabee is supposed to be bigger than GT200.

Intels fabs are somewhat ahead of those of TSMC, hence they can produce bigger chips somewhat easier, hence direct comparison is somewhat flawed. Though it holds some value.

IF this is causing problems for Nvidia, I am sure they have a backup plan. Get GT300 working, slash 200-series prices, do some PR stuff, rename, driver tricks, rename some more, more PR stuff. It is amazing how much Nvidia can do(and has done, as history suggests) without having new chips to show.
