It would be interesting if those cores could be re-enabled.
Nvidia's road to bringing the GF100 to market has been a bumpy one that will finally reach its first stop this Friday March 26 with the launch of the GeForce GTX 480 and GTX 470.
According to a story from Digitimes, which Nvidia refused to comment on, TSMC's 40nm yield is currently still under 50 percent which could mean that some GPUs are coming out less than perfect.
Rather than completely toss out the chip, Nvidia could disable the bad cores. Digitimes says that this resulted in a lower core count than the original 512; the GeForce GTX 480 will only have 480 cores and GTX 470 only 448, the website reported.
