The new chips include the high-end ATI Mobility Radeon HD 4800, balanced Mobility Radeon HD 4600, and power saving HD 4500 and HD 4300 Series, all based on 55nm production technology.
The new Radeon products for notebooks support Microsoft DirectX 10.1 technology, as well as full 1080p high definition video playback, provided by the Unified Video Decoder 2. Furthermore, the 4000 Series are the “first ever” mobile graphics solutions that have advanced hi-definition audio capabilities using HDMI with 7.1 digital surround sound and DisplayPort Audio.
Regarding power efficiency, the new GPUs feature ATI PowerPlay, ATI PowerXpress, and ATI Switchable Graphics technologies.
