A Guide to Intel’s Processor Sockets
Intel has consistently released new CPU sockets over the years to support newer and more powerful processors. Here’s a look at the history of Intel’s socket releases and their significance:
The Early Years
Intel’s earliest processors used simple DIP (Dual In-line Package) sockets on motherboards. However, the move to more powerful processors led to the development of more complex and specialized sockets.
The Socket Era
- Socket 7 (1995): Supported Pentium, Pentium II, Pentium III, and Celeron processors. One of the most popular early sockets.
- Socket 370 (1999): Designed for Celeron and later Pentium III processors.
- Socket 478 (2000): Supported a wide range of Pentium 4 and Celeron processors, offering a significant increase in pin count compared to previous sockets.
The LGA Era
Intel introduced Land Grid Array (LGA) sockets which eliminated pins on the processor, transferring them to the motherboard instead. This reduced the risk of damage to the processor during installation.
- LGA 775 (2004): Introduced with Pentium 4 processors and also supported Pentium D and some Core 2 Duo processors.
- LGA 1156 (2008): The first socket for the Core i-series processors.
