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.
“The ATI Mobility Radeon HD 4600 and ATI Mobility HD 4500 series offer outstanding performance per watt giving notebook manufacturers the ability to pack significantly more performance into thin designs as the previous years equivalent models,” said Bergman. “And for value oriented and ultrathin notebooks, these GPUs enable superior HD entertainment on the go coupled with low power requirements. We’re delivering a top-to-bottom line of mobile discrete graphics processors that deliver on the AMD hallmark of leading performance and energy efficiency.”
The ATI Mobility Radeon HD 4000 series features a wide range of power-efficient and performance optimized configurations that vary in terms of size, operating speed and performance to satisfy the discrete graphics requirements of products ranging from ultra-mobile sub-notebooks to high-end gaming portables, small form-factor desktop PCs and everything in between.
Unprecedented Performance
ATI Mobility Radeon HD 4000 series graphics also provide performance benefits for defense applications.
“A critical component of Mercury's Converged Sensor Network Architecture is pushing substantial computing capability closer to the sensor in embedded environments. GPUs have proven to be well-suited for this. Mercury’s relationship with AMD affords us the ability to leverage cutting-edge GPU technology into embedded systems for this purpose,” said Scott Thieret, Technology Director for GPU Computing at Mercury Computer Systems. “The dual ATI Mobility Radeon HD 4870 GPUs, as deployed in our Sensor Stream Computing Platform, provide a teraFLOP of floating-point performance in a single 6U VXS card. This unprecedented compute density in an embedded system allows Mercury to solve tough stream computing problems for our military and commercial customers who contend with stringent size, power, and weight constraints.”
The ATI Mobility Radeon™ HD 4000 series graphics processors have been designed into quality notebooks from many leading notebook manufacturers such as ASUS, MSI and others, with models planned for availability beginning in Q1 2009. For more information visit http://www.amd.com/mobility/hd4000.
