nVidia GT300 - GeForce GTX 380 yields are sub-30%

When we ran the TSMC yield story, we were left owing you an explanation. Time to clear that up too… why does TSMC have "f***** up" yields? Because the chip "some say doesn't exist" has disastrous yields. We refuse to be drawn into the speculation about whether the GT300 exists or not, since we have enough data on hand that would send nVidia Legal our way - but that was in the past, green guys have learned better ;-)
According to our sources close to the [silicon] heart of the matter, the problem is that nVidia has yields in the 20 percentage range. You've guessed, that is waaay [insert several "a"] too low for launch volume production. Even when TSMC improves the leakage issues [the company claims that the leakage issues are now the thing of the past], nVidia will probably send a new revision of silicon - the yields have to be get high enough to earn a little bit of money
