The next-generation chip, built for mobile PCs, is being touted as the most power-efficient processor the company has ever developed.
Intel's own Ultrabook platform will provide the flagship devices for the new hardware, making them 20 times more efficient than current Sandy Bridge laptops. Other benefits include all-day battery life, and lighter, thinner form factors.
"The 4th generation Intel Core processor family and our new line of low-power processors will usher in an era of unprecedented innovation in mobile computing," said Intel chief product officer David Pearlmutter.
Intel also revealed plans to incorporate speech, touch and gesture support into its Ultrabooks and PCs in a move that will fully optimise them for the upcoming Windows 8 operating system.
Machines powered by the Haswell Core processor are expected to arrive on the market in 2013.
