a week away from their grand unveiling, but already we've got word of the specs for NVIDIA's high end GTX 480 and GTX 470 cards. Priced at $499, the 480 will offer 480 shader processors, a 384-bit interface to 1.5GB of onboard GDDR5 RAM, and clock speeds of 700MHz, 1,401MHz, and 1,848MHz for the core, shaders and memory, respectively. The 470 makes do with 446 SPs, slower clocks, and a 320-bit memory interface, but it's also priced at a more sensible $349. The TDPs of these cards are pretty spectacular too, with 225W for the junior model and 295W for the full-fat card. Sourced by VR Zone, these numbers are still unofficial, but they do look to mesh well with what we already know of the hardware, including a purported 5-10 percent benchmarking advantage for the GTX 480 over ATI's HD 5870. Whether the price and power premium is worth it will be up to you and the inevitable slew of reviews to decide.
