The overhaul of Intel's Centrino technology, code-named "Napa," comes as the world's largest chipmaker is getting a boost from laptop sales, which are growing faster than the overall computer market.
At the heart of Napa is Intel's new Yonah microprocessor, which will be its first mobile chip to have two cores and will be built with the latest technology that etches circuitry more than 100 times thinner than a human hair.
That means the Napa system -- covering the Yonah processor, its attendant chipset and a new wireless chip -- will use 28 percent less power while performing 68 percent better than its predecessor, Keith Kressin, Intel's marketing chief for mobile platforms, told reporters.
Napa comes as Intel's chief rival, Advanced Micro Devices Inc, makes inroads in laptop computers with its line of Turion chips and is looking to one-up Intel next year by being the first to launch a 64-bit mobile processor.
A 64-bit processor is able to process chunks of data twice as large as a standard 32-bit chip. That will be important when Microsoft launches the next version of its Windows operating system, which will be optimized for 64-bit.
