The release of the latest Mobile Duron processors, which run at 1.1GHz and 1.2GHz, comes a year after the company first launched the chip and hot on the heels of the 1GHz version of the chip that was announced in mid-December. With built-in power management, the chips are designed for use in notebook computers and other situations where low power consumption is important.
In addition to the Mobile Duron, AMD also offers a higher-performance Mobile Athlon processor. The two chips represent the main competition to Intel's Mobile Pentium III and Mobile Celeron processors.
AMD said the new chips would cost $130 (£92) and $160 (£113) for the 1.1GHz and 1.2GHz versions respectively, when bought in 1,000-unit quantities. At the same time as announcing the faster chips, the company has cut the price of its six-week-old 1GHz Mobile Duron to $100 (£71). When it was launched the chip cost $160.
