Radeon HD 4770 GPU w/DDR

AMD on Tuesday launched its Radeon HD 4770 graphics processor as its latest performance product in the 4000 series for the desktop PC market. Featuring over 826 million transistors and the latest 40nm manufacturing process, the GPU offers performance starting at $99 (after mail-in rebate). The new card features third-generation hardware support for the latest DirectX 10.1 games (e.g., Battleforge, HAWX, S.T.A.L.K.E.R Clear Sky and Stormrise) as well as support for 128-bit GDDR5 memory (twice as fast as GDDR3 at the same clock speeds for better performance), and ATI CrossFireX, which enables a second ATI Radeon HD 4770 card to be added for a "near-linear" increase in performance.
