Socket M

The base M is a processor socket for Intel's mobile processors, the Core Solo series, Core Duo, Core 2 Solo, Core 2 Duo, and for the Yonah and Merom -based budget processors, the Celeron M and Pentium dual-core series. He is also known under the name mPGA478MT and is the successor of the base 479 Since the second half of 2007, will be replaced by the base P, but initially retained for the ULV processors, the Intel Core 2 Solo series, as the first chipsets for Socket P hold more power than the last chipsets for Socket M.

The base M has, despite the exact same number of pins on the socket 478 for desktop CPUs to a significantly different pin assignment, so it is mechanically and electrically not compatible with Socket 478 processors.
