Advanced Micro Devices (AMD), the US based chipmaker, has launched its energy efficient notebook chip, code named Griffin as well as platform based around Griffin called Puma, which will allow AMD to grow in notebook PC market. The company has developed Puma to deliver enhanced battery life, graphics and video processing and also improves overall system performance. AMD’s Puma will follow with Fusion, a chip which will integrate graphics into the processor core in 2009. The Puma platform would be build on the MD M690 mobile chipset and 65nm process-based Turion 64 X2 dual-core mobile technology. The company has developed the Puma due to MD’s next-generation notebook processor codenamed ‘Griffin’, along with AMD’s next generation ‘RS780′ mobile chipset. Currently, AMD chips can drop to 800 megahertz. The cores in Griffin would be able to drop to one-eighth the chip’s stated speed. Thus, a 2.4GHz chip, would be able to drop to 300MHz to conserve power. Griffin has two processing cores and the integrated memory controller, which shuttles data back and forth between the processing cores and memory. Puma manages the power through its feature, PowerXpress, which shuts off the discreet graphics processor in notebooks when they are running on batteries. Notebook will run on the graphics capabilities in the chipset in the unplugged mode. The chipset, Puma has new features, which are given below: 1) DirectX 10 graphics processing 2) Energy efficient HD multimedia support with unified video decoder 3) Integrated multi-monitor support 4) Native southbridge support for Nand flash with HyperFlash 5) PowerXpress. Puma not only incorporates the ‘Griffin’ processor and the ‘RS780′ chipset, but also incorporates ATI Radeon graphics, Nvidia chipset and graphics technologies, and industry-leading wireless technologies. According to AMD officials, the Puma Platform is taking important steps in system level optimization by adding intelligence and increased coordination between the CPU, GPU, and chipset.
