AMD's next step in their Radeon HD 5000 release strategy is the Radeon HD 5770 which is based on the new 40 nm Juniper core. It features 800 shaders and 1 GB of GDDR5 memory on a 128-bit bus. Essentially this makes the card perform like a HD 4870 but adds new features like DirectX 11, ATI Eyefinity and reduced power consumption.
