Intel officially introduced the Core i7 for a laptop. Processor with codenamed Clarksfield is known as the fastest for mobile platform. Intel introduced the latest Core i7 family in Intel Developer Forum (IDF) in 2009 which was held in San Francisco, 22-24 September 2009. There are three variants of Intel Core i7 introduced, Core i7 920XM, Core i7 820QM and Core i7 720QM.

Shmuel “Mooly” Eden, Vice President and General Manager of Mobile Platforms Group, Intel Corporation, said Core i7 on the laptop for those who want high-performance portable computers.
