The chipmaker on Wednesday launched a new 2.5GHz Pentium 4-M processor and two new Celerons running at 2.2GHz and 1.26GHz, respectively. The chips address several categories of notebook PCs and are the latest mobile processors from Intel since its new Pentium M debuted in March.

Gateway is among the first PC makers to adopt one of the chips. The Poway, Calif., company's new 600XL computer incorporates the 2.5GHz Pentium 4-M and sports a 15.7-inch screen and a DVD burner for a starting price of $2,499.
