ComputerBase has revealed AMD’s notebook processor roadmap for 2008, which list four "Griffin"-based chips. "Griffin" CPUs are part of the upcomnig "Puma" notebook platform. The roadmap shows AMD Turion 64 Ultra and AMD Turion 64 dual-core models, with 2MB and 1MB of L2 cache respectively. Both CPUs support DDR2 800MHz memory and have clock speeds ranging from 2GHz to 2.4GHz. Their power consumption ranges between 32 Watts and 35 Watts. There is also a single core Athon 64 chip with 1MB of L2 cache, DDR2 667MHz support, clock speeds starting from 1.9GHz, and a power consumption of 31 Watt. AMD also lists a range of "Sable" Sempron single-core chips with 512KB of L2 cache, 25W power consumption, and clock speeds starting from 2GHz. Codename "Sable" stands for the lower-end "Griffin" CPUs. Along with the new CPUs, "Puma" will deliver the RS780 mobile chipset with the DirectX 10 ready HD3200 integrated graphics and the Unified Video Decoder (UVD). In addition, the RS780 includes PowerXpress technology for dynamic switching between integrated and discrete graphics to extend battery life, as well as PCI Express 2.0 and HyperTransport 3.0 technologies. AMD has announced that the "Puma"/"Griffin"-powered laptops will start shipping at the end of the second quarter of 2008.
