Nvidia GeForce GTX 480 and GTX 470 Video Card Yields Are Poor
SemiAccurate is reporting that production parts have been coming back from TSMC for several weeks now, and the outlook for them is grim for NVIDIA on their GeForce GTX 480 and GTX 470 graphics cards. They claim that NVIDIA is still getting single digit percentages on Fermi graphics cards and if that is true it really is bad news for NVIDIA. If you like following this sort of thing then follow the link below and take a look at the ~3,400 word story on the issue! It is interesting and entertaining!
We first got word that production A3 GF100s were back in Santa Clara near the end of January. When enough of them rolled off the line to characterize the silicon, we hear there were no parties in Santa Clara. For those not interested in the ‘why’ side of things, the short answer is that the top bin as it stands now is about 600MHz for the half hot clock, and 1200MHz for the hot clock, and the initial top part will have 448 shaders. On top of that, the fab wafer yields are still in single digit percentages. Number one on Nvidia’s hit list is yields. If you recall, we said that the yield on the first hot lot of Fermis that came back from TSMC was 7 good chips out of a total of 416 candidates, or a yield of less than 2 percent.
