The heart of the platform is the new 7-series chipset with support for the ATI Mobility Radeon 3000 family of graphics and Wi-Fi support from a third-party chipset (such as Atheros, Broadcom, or Marvell).
The graphics come in several flavors. Most distinctive is the HD 3000 integrated graphics solution, which includes support for Avivo HD (for better hardware-assistend HD decode). AMD believes this will far outperform Intel's integrated graphics. In addition, AMD is offering three discrete graphics solutions; the HD 3400 family for mainstream systems; 3600 for performance; and 3800 for gaming. The big differences between these chips desls with the memory interface (64-bit for the 3400; 128-bit for the 3600; and 256-bit for the 3800); and the number of stream processors (40, 120, and 320 each).
All of the discrete solutions will support "hybrid graphics" which support both using the integrate chip and the discrete chip together; as well as "Power Xpress" which turns one of the chips off when it isn't needed to save battery power. All the chips support Direct X 10. In addition, AMD will be offering support for what it calls "ATI XGP" - essentially an external box with even more graphics that connects via special cable to the PCI Express bus. This will allow multi-monitor support, TV tuners, etc. It's a very cool idea.
