Website VR-Zone claims to have received what are supposedly the final specifications for the upcoming Nvidia GeForce GTX 480 and GTX 470 GPUs.
The site lists the following information:
GeForce GTX 480 : 480 SP, 700/1401/1848MHz core/shader/mem, 384-bit, 1536MB, 295W TDP, US$499GeForce GTX 470 : 448 SP, 607/1215/1674MHz core/shader/mem, 320-bit, 1280MB, 225W TDP, US$349 Internal benchmarks reveal that GeForce GTX 470 is some 5-10% faster than Radeon HD 5850 and similiar for GeForce GTX 480 over the Radeon HD 5870. Interestingly, the TDP of GeForce GTX 480 is almost similar to Radeon HD 5970 which is a dual GPU card. Interestingly, our sources revealed that there are indeed plans for dual Fermi cards and the TDP of the card is probably gonna be mind blowing.
UPDATE: Above quoted information has been updated to reflect new information reported by VR-Zone.
Also found on VR-Zone's forums is a picture from Turkish website DonanimHaber of what is purported to be the first Nvidia-made picture of the GeForce GTX 480 card:
