The ATI Radeon HD 4870 is a video card reference specification designed by AMD/ATI. It includes a 55nm RV770 GPU (graphics processor) and 512MB of GDDR5 memory, a state of the art addition, connected through a 256-bit interface. With 956 million transistors, it tops ATI's last highest end dual GPU card, the Radeon 3870x2 - toping its own last generation model the 3870 by an even larger margin. Launched at a suggested retail price of
299 199 dollars (see details for more information), the Radeon HD 4870 has been selling quite well, beating or at the very least matching Nvidia's offerings in performance as well as price.
With the introduction of the Nvidia GTX 260 Core 216, ATI has begun to offer 1GB models - offering higher performance which can match that of the newly revised Nvidia card. This new competition has also led to a large amounts of price cuts - first seen with the original GTX 260. The original 4870 has had it's MSRP officially dropped 1/3rd to remain desirable in harder economic/competitive times.
