AMD today announced ATI Mobili These graphics processors support for the latest Microsoft DirectX 10.1 games, a home theatre-quality HD multimedia experience, and energy-efficient features for long battery life.

The ATI Mobility Radeon HD 4800 series support TI CrossFireX technology to deliver up to one teraFLOP of performance power. ATI Mobility Radeon HD 4600 series offers a balance of performance and energy efficiency. Optimal for thin and light notebooks, the ATI Mobility Radeon HD 4300 and ATI Mobility Radeon HD 4500 series provide high battery life for anyone on the go.

Asus has already announced its first notebooks with the ATI Mobility Radeon HD 4650 graphics, the ASUS N51Tp, N81Vp and the F81Se.

The ATI Mobility Radeon HD 4800 series graphics processors are the first to support GDDR5 memory technology, providing nearly twice the memory bandwidth of GDDR3 and GDDR4. Also featuring support for Microsoft DirectX 10.1, the entire ATI Mobility Radeon HD 4000 series is ready to tackle the demands of next-generation game titles. Extreme gamers can push the boundaries of gaming performance with the ATI Mobility Radeon HD 4870 graphics processor delivering up to 1.8 times the performance compared to previous AMD discrete mobile graphics processors and with ATI CrossFireX technology, combine the performance of two ATI Mobility Radeon graphics processors.

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 vibrant picture to viewers. Specifically designed for HD video enthusiasts, ATI Avivo HD is found throughout the ATI Mobility Radeon HD 4000 series and provides 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 are also the first ever mobile graphics solution that has advanced hi-definition audio capabilities using HDMI with 7.1 digital surround sound and DisplayPort Audio.

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 percent over the previous generation. Additional power-saving features include ATI PowerPlay, ATI PowerXpress, and ATI Switchable Graphics technologies.

ATI PowerPlay 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.

The ATI Mobility Radeon HD 4000 series graphics processors have been designed into otebooks from many notebook manufacturers such as ASUS, MSI and others, with models planned for availability beginning in Q1 2009.
