Definition of a CPU Socket

This CPU socket is centered on the back of the motherboard.

A computer central processing unit (CPU) is the brain of the computer. This chip runs all processes on a computer. A CPU socket holds the CPU and is part of a computer motherboard.

Function

The CPU socket forms a connection between the CPU and the rest of the computer motherboard. This connection allows the CPU to interface with other computer hardware on the motherboard.

Identification

CPU sockets may be located anywhere on a computer motherboard. They feature a series of small holes into which the bottom of the CPU fits. Most CPU sockets feature a latch to lock the processor in place. CPU sockets are square. Desktop and laptop computers usually have a CPU socket measuring between 1.5 and 2 inches in length and width.

Types

AMD and Intel produce most central processing units sold around the world. As of July 2010, the current AMD CPU socket, used with Phenom II, Athlon II and Sempron processors, is Socket AM3. Intel uses Socket H (LGA 1156) for its Core i3, Core i5 and Core i7 line of processors.
