GeForce GTX 400 series yield is still lower than 50%

Nvidia's initial batch of GeForce GTX 480/470-based graphics cards will have fewer cores than the originally expected 512 due to low 40nm yield at Taiwan Semiconductor Manufacturing Company (TSMC), according to sources from graphics card makers.

Since TSMC's 40nm yield currently is still lower than 50%, Nvidia will block some of the graphics cores with problems on the card. As a result, the GeForce GTX 480 will only have 480 cores and GTX 470 only 448, the sources noted.
