Unless you missed all of our past coverage, you'll have heard that Nvidia is cooking up a smaller, less powerful graphics processor based on its Fermi architecture: the GF104. Such a chip would allow Nvidia to populate lower echelons of the DirectX 11 GPU market, of course, but the folks at Fudzilla now reports that a top-of-the-line, dual-GF104 product is also in the works.
Fudzilla writes that Nvidia has internally canceled a dual-GPU card based on the GF100—the elephantine chip that powers the GeForce GTX 470 and 480—because it would reportedly have a thermal envelope of about 375W. That'd be quite a step up from even the GTX 480, which draws up to 250W, by Nvidia's count.
Instead, the dual-GF104 product is said to have a TDP of just 150W. Fudzilla doesn't discuss other specs, but word out on the web is that the GF104 will feature 256 stream processors, 32 ROPs, and a 256-bit GDDR5 memory interface, down from 480 SPs, 48 ROPs, and a 384-bit interface width for the GTX 480. If all of this rumored information happens to be correct, the missing bits and pieces will help Nvidia achieve much lower power consumption.
An Nvidia product with dual GF104 GPUs would likely compete against the Radeon HD 5970, which has two of the Cypress chips that also power AMD's high-end single-GPU cards. The 5970 doesn't come cheap, with prices starting at $699.99 shipped at Newegg, so Nvidia may shoot for a similar price range.
