Socket M is a CPU interface introduced by Intel in 2006 for the Intel Core line of mobile processors ^[1]. It is used in all Intel Core products, as well as the Core-derived Dual-Core Xeon codenamed Sossaman. It was also used in the first generation of the mobile version of Intel's Core 2 Duo, specifically, the T5x00 and T7x00 Merom lines (referred to as Napa), though that line switched to Socket P (Santa Rosa) in 2007.

Relatives

Although it may seem identical, Socket M is not pin-compatible with the older mobile Socket 479, the older desktop Socket 478 or the newer mobile Socket P.
