Advanced Micro Devices Inc. rolled out a new package of chips for laptops Wednesday, a major overhaul of its mobile lineup the chip maker hopes will help it climb out of a deep financial trough.

The Sunnyvale-based company, saddled with debt and hurt by product delays, is betting consumers will gravitate toward its new Turion brand processor and related chipset - part of a package that chip makers call a “platform” and sell together - because of their focus on high-definition video playback.

This new generation of Turion laptop chips will appear at launch in twice as many different computers - from Hewlett-Packard Co., Acer Inc., Toshiba Corp. and others - as the previous generation, released two years ago, AMD said.
