NVIDIA is planning a massive transition of the G200 architecture to the newer 55nm silicon fabrication process. With this, maintaining electrical constraints, the clock speeds of the GPU can be increased to levels that make them highly competitive, while also cutting manufacturing costs. With the newer G200b core running hypothetically cooler, the company is also planning a dual GPU card named the GeForce GTX 295. Its single GPU flagship offering will be called GeForce GTX 285.
While nothing substantially new is on the cards, GeForce GTX 285 has everything that makes it identical to the GTX 280, specifications wise, except for the clock speeds. This is where, NVIDIA gets to take the advantage of the superior electrical and thermal efficiencies of the 55nm core to step up clock speeds and thereby increase performance. While the clock speeds are unknown at this point in time, it is predicted that the new card has a 10% performance increase over the GeForce GTX 280. The card continues to be based on the NVIDIA P891 PCB the current cards use, and hence the GPU gets to use the high-grade power circuitry at its disposal to gain high clock speeds. The power consumption of the new card is pitted at 183W (down from 236W for the GTX 280). The would need two 6-pin PCI-Express power inputs. The GeForce GTX 285 is slated for January 2009.
