Intel's laptops vs. AMD's chips

Tag: industrial portable computer

The hot laptop market has sparked a war among computer chip companies — and they're not just fighting over who can build the fastest processor.

Intel (INTC) on Monday rolled out Centrino 2, its next-generation laptop chips. Centrino 2 laptops are faster than their predecessors. But their biggest benefits are other features, such as better graphics and battery life.

Advanced Micro Devices (AMD), Intel's chief rival, released a similar set of laptop chips last month. Graphics-chipmaker Nvidia, best known for desktop components, also rolled out a laptop line.

"It's a big shift," says AMD Vice President Patrick Moorhead. The number of laptops sold will outpace desktops by 2009, Intel CEO Paul Otellini predicts. (Laptop revenue already exceeds desktops, because laptops are usually more expensive.) That's prompting chipmakers to put new emphasis on the problems that arise in small, portable computers.

•Battery life. The best laptop in the world isn't worth much when its battery dies. Intel's new chip line features an ultra-low-power processor and other energy-saving tools. AMD's chips can detect whether a computer is plugged in and adjust power levels accordingly. (Other features also help.)
