Intel's Moorestown chips include a low-power single-core Atom processor and graphics processor cores for high-definition video, designed for use in smartphones and tablet computers.
Arm has stolen an early lead in the tablet computer market with Dell and Lenovo showing tablets based on Arm designs and Apple's A4 chip for the iPad designed on an Arm Processor.
Intel has made significant power consumption and performance improvements for video and web browsing that should make Moorestown chips competitive in the handheld market, say analysts.
The new chip set supports 10 days standby time and up to five hours Web browsing and incorporates new low power states to run the chip on as little as 100 microwatts, Intel claims.
Moorestown chips are designed to give tablet devices PC-like capabilities such as multi-tasking and video-conferencing.
Devices based on the Moorestown chips are expected to be announced in the second half of the year.
Although the 45nm Moorestown platform is aimed at the smartphone and tablets market, observers say Intel's next-generation 32nm chipset will compete more effectively, according to US reports.
