Atom could challenge Intel's higher-end processors

The use of Intel's Atom chip in sub-notebooks could undercut sales of its higher-end chips, analysts said on Tuesday.

Atom chips are low-cost and low-power processors that mostly are being used in netbooks designed for Web surfing and e-mail. With Fujitsu's new LifeBook U820 tablet PC, introduced on Tuesday, Atom chips are now being used in laptops with small screens, packed with networking and multimedia features.

Tablet PCs usually feature Intel's more expensive Celeron and other dual-core chips, but using Atom chips in such systems could undercut sales of those higher-end chips, analysts said.

Other than the screen size, the U820 mini-notebook offers capabilities similar to those of traditional laptops. It weighs 1.32 pounds (598 grams), includes Bluetooth and 802.11n wireless capabilities, and has a built-in webcam and high-definition video decoding. It also has a built-in Garmin GPS (global positioning system) receiver for navigation. It can be configured with as much as 1G byte of RAM and includes a hard disk drive as big as 120G bytes, as well as solid-state drive options.

The U820 comes with a 5.6-inch swivel touch screen and runs the Windows Vista OS. A four-cell battery runs the tablet for up to seven-and-a-half hours, according to Fujitsu. Prices start at US$999.

The U820 is a mini-notebook targeted at consumers and mobile users looking for touch technology, said Kevin Wrenn, senior vice president of PC business and operations at Fujitsu. Atom's low-cost and low-power features were a consideration in adopting the processor for the laptop, Wrenn said. Upcoming laptops from the company with screens up to 12 inches will incorporate Atom, he said.
