The AMD-ATI hybrid bears fruit: Puma Laptop Platform
 

The various components of the Puma platform will be largely familiar to those who know AMD's desktop products, but the big exception here is the new mobile processor design, code-named "Griffin." Griffin is a mix of old and new, combining a pair of K8-style execution cores with Phenom-style glue logic and power-saving measures. The chipset itself is manufactured on AMD's 65nm SOI process, and each core packs 1MB of L2 cache, for a total of 2MB L2 per chip. AMD says this new mobile processor has three independent power planes, one for each CPU core and a third for its integrated north bridge (with a HyperTransport link and memory controller). Griffin can scale voltage up and down as needed, in response to demand, for each of these three power planes. The north bridge supports HyperTransport 3.0, for added bandwidth, and it can drop from 16 lanes to eight, or even disconnect itself temporarily, in order to conserve power.
