NVIDIA GeForce GTX 400 cards to be down on cores
NVIDIA's first GeForce GTX480/470 graphics cards will reportedly have less than the 512 cores originally expected because of a low yield of 40nm chips at its supplier, Taiwan Semiconductor Manufacturing Company (TSMC). Leaks have now claimed the the GeForce GTX 480 will drop from 512 to 480 cores, while the GTX 470 will have 448 cores. TMSC's 40nm yield is less than 50 percent because of the inherent difficulties in the manufacturing of the technology.
NVIDIA is still believed to be launching its GeForce GTX 400-series cards on the widely anticipated March 26th release date, but shipments in large quantities wouldn't begin until April 6th. The GeForce GTX $480 would be less expensive than first feared but would still cost $499, while the GTX 470 would be priced at $349. [via DigiTimes]
