ATI might prep radeon HD 4860

The colleagues from TPU found out through it168 that AMD is working on a Radeon HD 4860 graphics card. This part is expected to arrive for around $130.

The Radeon HD 4860 seems to have been already taped out, sampled, and pictured by sections of the Chinese media. At the heart of it is the RV790 GPU in a different configuration codenamed RV790GT. It has 640 stream processors instead of 800 on the HD 4850, except that it uses a 256-bit GDDR5 memory interface, and effectively higher clock speeds.

The core is clocked at 700 MHz, and the memory at 750 MHz (3000 MHz effective). The PCB shows the card to powered by a single 6-pin power connector.
