Vari-Bright was initially a software feature, but hardware support could reduce power drawn by up to 50% compared to the software.
Energy efficiency was also achieved by making the cards at the advanced 40-nanometer manufacturing process.īattery life on laptops could also increase with native support for Vari-Bright on the graphics cards. The cards consume less power in idle mode by adjusting the engine and memory clock, Rehman said. The GPUs will also be able to play back Blu-ray video in the Windows Aero mode, a task which was difficult to handle on earlier graphics cards.īeyond performance improvements, the cards are more power-efficient. The older 4000 series chips were capable of processing one high-definition and standard-definition stream at the same time. The chips will also include support for a feature called UVD2, which will allow laptops to decode two high-definition video streams on a single GPU. The tools also help free up CPUs by off-loading multimedia tasks to graphics processors, which could speed up overall laptop performance.įor example, processing of Flash videos could be off-loaded from the CPU to the latest ATI graphics cards, which could significantly speed performance.
That is partly done by native hardware support for DirectX 11 tools that are built into Windows 7 by Microsoft.ĭirectX 11 tools include a set of APIs (application programming interfaces) for realistic images and sound when playing games or watching movies.
The units can harness the parallel processing capabilities of GPUs to improve gaming and application performance on PCs, Rehman said.
The high-end 5800-series graphics card includes 1.04 billion transistors and provides computing power of up to 1.12 teraflops, which AMD claims is the highest in the laptop category. The 5000-series cards outperform the older 4000-series graphics cards by up to 40%, Rehman said. The graphics chips offer bandwidth for laptops to run two Blu-ray streams at once, said Asif Rehman, product manager for AMD's mobile graphics business. The company released ATI Mobility Radeon HD 5000 series graphics cards that are the fastest laptop processors the company has released to date. Advanced Micro Devices announced new DirectX 11 mobile graphics processors that should bring improved graphics and application performance to Windows 7 laptops, the company said on Thursday.
