Nvidia GeForce 8800 Specs A Week Before Launch

According to DigiTimes, sources in Taiwan again confirmed that Nvidia’s upcoming GPU (graphics processing unit) GeForce 8800 (formerly codenamed G80) is designed to fully support Microsoft’s DirectX 10 Shader Model 4.0 technology. Nvidia is scheduled to officially launch the new GPU on November 8, the sources said.

The sources also revealed that two expected versions of the GeForce 8800, the GeForce 8800 GTX and the GeForce 8800 GTS, will vary in features such as the number of stream processors (128 and 96, respectively), core clock (575MHz and 500MHz) and shader-engine clock (1350MHz and 1200MHz).

Both versions will be SLI ready, with 16x full-screen antialiasing and 128-bit floating-point high dynamic-range (HDR) lighting technology. Using Nvidia’s reference designs, makers will roll out graphics cards equipped with a recommended 768MB or 640MB of on-board memory for the GeForce 8800 GTX and the GeForce 8800 GTS, respectively, the sources stated. With a different memory clock (900MHz versus 800MHz) and memory interface (384-bit versus 320-bit), the cards will vary in memory bandwidth (86.4GB/s versus 64GB/s) and texture fill rate (36.8 billion versus 24 billion texels per second), according to the sources.

Taiwan-based graphics-card makers are now completing their last-minute preparations to launch their own products in line with Nvidia’s launch in the middle of next week, the sources said.
