The specifications of an upcoming Asus graphics card, the EN8800GTX, have been posted online to give a pretty good idea what Nvidia's upcoming GeForce 8800 GTX chip - aka 'G80' - will offer, including DirectX 10 Shader Model 4.0 support and Nvidia's Quantum Effects Technology.

The EN8800GTX is a two-slot card that requires a pair of extra power feeds, according to information posted on Chinese-language website MyChat. The report claims the card's 8800 GTX chip is clocked to 575MHz while the 768MB of GDDR 3 memory runs at 900MHz (1.8GHz effective). The memory connects across a 384-bit bus.

The board has s-video output and a pair of dual-link DVI port. There's no HDMI port, but the board is HDCP compliant, the report claims.

As expected the 8800 GTX GPU is based on a unified shader archicture. It incorporates what Nvidia will apparently call its GigaThread technology, suggesting numerous pixel processing pipelines.

The site suggests the 768MB board will retail for around $540, with a 640MB versio, the EN8800GTS coming in at $410.

There's no indication of availability, but Nvidia is expected to announce its G80 chip mid-November. ®
