Intel revealed dual-core versions of its Core i5 and Core i7 "Sandy Bridge" laptop processors will arrive on February 20th. The new chips will run at speeds from 1.4GHz to 2.7GHz and feature a TDP of 14W to 35W.

"The new microprocessors will draw between 17 watts and 35 watts of power and run at speeds between 1.4GHz and 2.7GHz, according to the chip maker's website. The Sandy Bridge microprocessors, launched in early January, integrate a CPU and graphics processor in a single chip.

The first Sandy Bridge processors to ship were quad-core chips, mainly for high-end laptops. The dual-core chips will likely go into end-user and ultraportable laptops, many of which were shown at last month's Consumer Electronics Show. Fujitsu said it plans to use dual-core Core i7 chips in its high-end ultraportable laptops".
