Currently, Intel is pushing its Core 2 brand of CPUs, and offers its older "Santa Rosa Refresh" platform (based on the 96X chipsets) and "Montevina," which combines its 45-nm Penryn CPU with its "Cantiga" chipset (primarily the PM45 without graphics and the GM45 with X4500 graphics). Basically, this is similar to the Eaglelake desktop chipset, but designed for mobile systems, with more power management, but support for fewer memory and PCI express slots. Packages that include Intel's wireless networking support are called "Centrino 2."
Next year's platform is called "Calpella", which is based around the mobile version of the "Ibex Peak" chipset. As with the desktop platform, it will be available with two basic CPUs: a four-core version called Clarksfield; and a dual-core called Auburndale. The quad-core chip will only support integrated graphics, while the dual-core chip will be available in two versions - with or without graphics on the CPU package.
On the AMD side, the primary processors are branded Turion, and there are two popular versions Turion 64 X2 and Turion X2 Ultra, once codenamed "Griffin".
Both are dual-core chips based on the Athlon design, but Turion has some special features designed for mobile use, allowing it to adjust the voltage to the memory and each core. The Turion X2 Ultra brand means that it has an AMD chipset supporting it, with features such as a new mobile-optimized memory controller, and power-optimized HyperTransport™ 3.0. You may also see single-core designs, called Mobile Sempron.
I'm still seeing some systems in the market based on the older "Kite Refresh" architecture, but AMD's focus this year is on its "next-generation AMD notebook" platform" formerly codenamed "Puma." This includes a Turion X2 Ultra and AMD's M780G chipset, which includes ATI Mobility Radeon 3000 series graphics, as well as support for hybrid graphics. AMD does not make its own wireless chips, so you'll typically find third-party Wi-Fi chips. AMD has been particularly aggressive in positioning this against Intel systems with integrated graphics.
"Shrike" is the next-generation of AMD's mobile platform technology, scheduled to debut in 2009. While the company has not been very specific about details, I'd expect to see processors based on the 45nm process, as well as chipsets to match. The "Shrike" platform will be the first AMD product to use the "Fusion" architecture which will incorporate the CPU, memory controller, and GPU into a single die, or Accelerated Processing Unit (APU), codenamed "Swift". Within this, the company is planning a new CPU core, codenamed "Stars."
