AMD RV670-based graphics card pictured

AMD introduced the Radeon HD 2900 Pro yesterday, but the company appears to have more mid-range cards up its sleeve. At least, one would think so after a trip to the Chinese-language Coolaler forums, where a member has gotten hold of an MSI prototype card based on an unannounced AMD RV670 graphics processor.

Judging by the automated translation and a few Catalyst Control Center screenshots posted in the forum thread, the card's "RV670-XTX" GPU is based on TSMC's 55nm process technology, packs 320 stream processors, runs at 600MHz, and features Shader Model 4.1 capability. The card also has a 256-bit memory bus, 256MB of Hynix GDDR3 memory clocked at 900MHz, PCI Express 2.0 support, and a single-slot cooler. Despite the single-slot cooler, the RV670 GPU appears to be fairly voluminous, and the prototype card is outfitted with a six-pin PCI Express power connector.

Previous rumors we've heard regarding the RV670 GPU talked of Radeon HD 2950 Pro and Radeon HD 2950 GT graphics cards scheduled for a launch either at the end of this year or at the start of the next. Where the prototype card's "XTX" suffix fits into that pattern isn't clear, however. Thanks to Fudzilla for the tip.
