Advanced Micro Devices Inc may make some of its largest inroads into the fast-growing laptop computer market thanks to a new generation of power-efficient chips to be unveiled next week.

People familiar with the matter who work for AMD said the company’s latest microprocessors are expected to be included in 109 mainstream laptop models in the coming months, the company’s best showing during the crucial back-to-school sales season. Last year, AMD’s chips were available in 40 laptop models.
