Chip maker, Intel has laid out the criteria for notebooks called Ultrabooks at the ongoing Computex trade show in Taiwan.

Intel is planning to make its Core processors more energy efficient and start utilizing the 3D chip technology in the first half of 2012. The technology will power Ultrabooks that are expected to account for 40 percent of the overall notebook market by the end of 2012, according to the company.

Intel has also said that the atom processors that are used in laptops at present will be redesigned every year instead of a two year cycles.

“These computers will marry the performance and capabilities of today's laptops with tablet-like features and deliver a highly responsive and secure experience in a thin, light, and elegant design,” the company said.

Intel also said that the Ultrabook will be shaped by Moore's Law and silicon technology. Intel intends the manufacturers to make Ultrabooks measuring 20-millimeter or less and with a price of under $1,000. The company is pointing to "instant on" functionality through "smart connect" and background connectivity "rapid start."

ASUS is expected to launch the UX21, which will be the first device in this category, later this year.
