LGA 1156 is a type of CPU socket used by Intel for their processors. Introduced in 2009, it supports various Intel Core i7, i5, and i3 processors, primarily from the Nehalem and Lynnfield families. The socket features 1156 pins that connect the CPU to the motherboard, allowing for communication between the two. This socket was designed to provide improved performance and energy efficiency compared to its predecessor, LGA 775. It supports technologies like Hyper-Threading and Turbo Boost, enhancing multitasking and processing speed. However, LGA 1156 has since been succeeded by newer sockets, such as LGA 1155 and LGA 1150.
