Later this month, AMD is expected to launch the ATI Radeon HD 4550 graphics processor (GPU). Its board SKU details have surfaced. The RV710 graphics processor will make it to the grass-root of entry-level and high-definition media grpahics boards. It is based on the 55nm silicon fabrication process. The GPU has a transistor count of 242 million, it has 80 stream processors. It is engineered in a way that makes it draw less than 25W. In the form of reference designs, AMD will release two cards: a full height, passively cooled 512 MB DDR3 version, and a low-profile, 256MB fan-heatsink cooled card. Both models have core clock speeds of 600 MHz with the memory clocked at 800 MHz on a 64-bit wide memory bus. The GPU schematic shows it to have 8 texture address and 8 texture filter units. There's only one render back-end. The 512MB variant is expected to be priced at US $49~59, while the 256MB variant in the $39~49 range. These cards are expected to compete with the GeForce 9400 GT GPU.
