Socket M (mPGA478MT), also known as Socket 479 mPGA is a CPU interface introduced by Intel in 2006 for the Intel Core line of mobile processors [7].
Technical specifications
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 Refresh), though that line switched to Socket P (Santa Rosa) in 2007. It typically uses the Intel 945PM/945GM chipsets which support up to 667 MHz FSB and the Intel PM965/GM965 which allows 800 MHz FSB support, though the Socket M, PM965/GM965 combination is less common.
Relation to other sockets
Although it may seem identical, Socket M is not pin-compatible with the older desktop Socket 478 or the newer mobile Socket P; it is also incompatible with most[8] versions of the older mobile Socket 479. Pentium III-M processors designed for the first version of Socket 479 will physically fit into a Socket M, but are electrically incompatible with it.[9] Although conflicting information has been published, no 45nm Penryn processors have been released for Socket M.
