CPU

The logic circuitry that reacts to and interprets the fundamental commands that power a computer is called a processor (CPU). Since it interprets the majority of computer commands, the CPU is regarded as the primary and most important integrated circuits (IC) chip in a computer.

Each CPU type has its own socket, which goes by a name like LGA1700, AM4, AM5, or TR4, to mention a few common ones. The motherboard must have the exact same socket in order for the CPU to work with it. This is typically the first step in selecting new components for your own computer build: Select a CPU, look up the socket it has, and then select a motherboard that works with it.

To enable CPU interaction with your motherboard, each CPU socket has distinct pin layouts and physical measurements.
Because AMD and Intel, the two main CPU brands, produce a wide range of CPUs with various sockets, you will need a motherboard that is compatible with AMD for AMD CPUs and an Intel motherboard for Intel CPUs.
That cannot be avoided. However, that's not all: The motherboard must have the appropriate socket for the specific CPU you want to purchase (or already own), in addition to being designed to support AMD or Intel CPUs. After all, AMD and Intel each have a wide variety of socket types.
