After first announcing it last April, AMD has now officially launched its Puma mobile platform, which is set to go head-to-head with Intel's Centrino platform. Puma is AMD's first attempt at a complete mobile platform and provides much stronger specifications than the company has had previously. In order to be branded as part of the Puma platform, notebooks must come with a Griffin CPU, RS780M chipset and WiFi adapter, with the option of a discrete graphics card. AMD has integrated a number of power saving features into the Puma platform, including the ability to dynamically change individual CPU core frequencies depending on processor load and PowerXpress technology, which can automatically switch from discrete external graphics to less power-hungry integrated graphics when running on batteries - without the need to reboot. Puma certified systems are expected to ship from the end of the second quarter this year, with prices ranging from around $700 to $2,500 at launch.
