Which feature distinguishes LGA sockets from PGA sockets?

LGA (Land Grid Array) sockets are characterized by having pins on the socket itself instead of on the processor. This design allows the processor to connect to the socket through small pads that make contact with the pins, which can improve the contact points and stability of the connection. The absence of pins on the processor makes LGA sockets generally more robust, as there is less risk of damaging the processor during installation or removal, which often occurs with PGA (Pin Grid Array) sockets where the processor has pins that can be bent or broken.

In contrast to LGA sockets, PGA sockets feature pins that protrude from the processor, which are inserted into holes in the motherboard's socket. This fundamental difference in design directly influences the handling and installation process of CPUs in systems that utilize these socket types. Additionally, PGA sockets are often considered slightly older technology compared to LGA designs, which are increasingly preferred in modern motherboard architectures, particularly in higher-end systems.
