HD multimedia experience

Using AMD's second generation Unified Video Decoder (UVD), the CPU is freed from other tasks so even when managing processor-intensive content such as Blu-ray movies, users can still instant message friends or conduct virus scans in the background without interruption. This also helps lower power consumption and reduces the need for high fan settings, enabling a quieter experience.

DVD upscaling allows for enhanced picture quality when watching standard definition content on 1080p HDTV, while dynamic contrast adjusts the contrast and brightness during scenes to bring a crisp, vibrant picture to viewers. Specifically designed for HD video enthusiasts, ATI Avivo HD, an advanced image and video processing display technology, is found throughout the ATI Mobility Radeon HD 4000 series and provides brilliant colours, sharp images, and smooth playback of Blu-ray and HD video content on HD-capable panels, monitors or televisions.

In addition, selected ATI Mobility Radeon HD 4000 series graphics processors models have advanced hi-definition audio capabilities using HDMI with 7.1 digital surround sound and DisplayPort Audio to create an immersive, home theatre-class experience.

Energy efficiency

The new mobile graphics family features energy efficient, second generation 55nm process technology that, in the case of the ATI Mobility Radeon 4870 GPU, delivers an increase in performance-per-watt of more than sixty per cent over the previous generation. Additional power-saving features include ATI PowerPlay, ATI PowerXpressT, and ATI Switchable Graphics technologies.

ATI PowerPlay, an activity-based power management technology, intuitively conserves energy at idle or when demand is low and automatically adjusts between low and high states for greater performance when needed and energy conservation for long battery life.

ATI PowerXpress and ATI Switchable Graphics technologies dynamically switch between the ATI Mobility Radeon HD 4000 series discrete graphics processor and the integrated graphics processor in the notebook—all in real-time without needing to reboot—to help provide exceptional performance when needed and to help extend battery life when on the move.
