Socket M denotes an electrical processor interface for Intel's mobile processors of the Core Solo , Core Duo , Core 2 Solo , Core 2 Duo series and for the Yonah or Merom-based budget processors of the Celeron M and Pentium dual-core series. The mechanical processor socket is known as the mPGA478MT. There are also mainboards that use the mechanically compatible processor socket mPGA479M of socket 479 . It has been replaced by Socket P since the second half of 2007, but will initially be used for the ULV processors of the Intel Core 2 Solo series, since the first chipsets for Socket P consume more power than the last chipsets for the socket M.
Socket M is the successor to Socket 479. A processor for Socket M fits mechanically into a Socket 479, but has a different pin assignment and is therefore not electrically compatible with mainboards designed for Socket 479 processors. Even with desktop processors for Socket 478 , Socket M is neither mechanically nor electrically compatible, despite the same number of pins.
