Manufacturer Socket Used For
Intel Socket 2011Intel’s most recent LGA socket. Used mostly by gamers for six 
core i7 processors.
Intel Socket 1366Workstation class computer using the i7 core or the Xenon 
3XXX series. Has the pins on the motherboard.
Intel Socket 1156The average consumer socket for i3, i5, and i7 processors.
Intel Socket 1155A   newer   version   of  the  socket   1156.   Although  it   supports

Motherboards are usually listed with the socket type as one of the specifications. CPUs 
are listed with the type of socket they require. Therefore, picking a motherboard which 
will work with a particular CPU mostly consists of checking on the sockets. When in 
doubt, it is best to check with the manufacturer of the motherboard in order to see 
which processors are compatible with it.
