AMD's graphics label ATI today extended its next-wave hardware into the mainstream. The Radeon HD 5770 and Radeon HD 5750 scale back to a 128-bit memory bus and significantly fewer effects cores but still have the full DirectX 11 and OpenGL 3.x feature sets of the 5800 series as well as support for multi-display Eyefinity. They remain dual-slot cards but consume much less power at 108W peak for the 5770 and 86W for the 5750.
