With Nvidia's next-generation Fermi graphics cards now just a week away, some new details have trickled in courtesy of Turkish site donanimhaber.com and VR-Zone.com. According to the publications, the GTX 480 will offer a total of 480 shader processors, a 384-bit interface working with 1.5GB of onboard GDDR5 RAM, and clock speeds of 700MHz, 1,401MHz, and 1,848MHz for the core, shaders and memory respectively.

Measuring around 26cm in length, or roughly 2cm less than the Radeon HD 5870, the card will draw power from a six-pin + eight-pin power connector combination and feature dual-link DVI and mini-HDMI outputs. Pricing is supposedly set at $499 and the TDP rating is quoted a being below the 300W threshold, apparently at 250W. Leaked pictures show the card will occupy two slots and feature a cooling system design with protruding heatpipes.

The less powerful GTX 470 on the other hand will reportedly make do with 448 shader processors while offering a core clock of 607MHz, shader clock of 1,215MHz, and a memory clock of 1,674MHz. The card will have a 320-bit memory interface and 1280MB of GDDR5 memory, along with a TDP of 225W and a more sensible $349 price tag.

According to VR-Zone, internal benchmarks reveal that the GeForce GTX 470 and GTX 480 are some 5-10% faster than the Radeon HD 5850 and 5870 respectively. Such estimations are of course unofficial, but we'll have clearer idea of the value behind these cards when benchmarks start popping up after next week's launch.
