Difference Between Logic Board And Motherboard

A logic board is a circuit board inside a computer where all the electrical components are wired together. The motherboard is the central part of a computer, or a computer’s main circuit board, providing a means for connecting different components. A computer motherboard consists of one or more printed circuit boards that connect to the logic board.

Logic boards and motherboards are basically the same thing. In a computer, the logic board is the part that is responsible for all the electrical components. As a general rule, when a motherboard is referred to, it is usually referring to the logic board.

 In Late 1980s and 1990s the people called motherboard a logic board.

What are the differences between the logic board and motherboard?

The difference between a logic board and motherboard is that logic boards are small printed circuit boards that contain the chips of the CPU and the other components of the PC while motherboards are the mainboards for the system.

Motherboards provide power to the system components and also provide interfaces for all other components of the PC to communicate with each other.

Motherboards usually come with a number of ports and sockets, the power supply, a number of expansion cards and various other things that we have not discussed here.

It is always advisable to consult the motherboard manual for the specific requirements and specifications of your motherboard if you are to choose the right motherboard for your system.


Logic board is a generic term used for the device that houses the processor. A logic board is also known as the motherboard, CPU board or Mainboard. It is a printed circuit board that is equipped with a microprocessor and the other components.

A logic board is a main component of your computer. It houses the processor, RAM, storage, video card, sound card and other components.


Is there really a difference between a logic board vs motherboard?

There are several differences between a logic board and motherboard.  Most people would be familiar with the former, since it’s what is typically in the CPU. In this scenario, the motherboard connects to both the RAM and the logic board. A motherboard usually has slots where RAM (Random Access Memory) or hard drives can be plugged in. This allows you to add more RAM or hard drives without buying a new computer.

Is the motherboard and logic board the same thing?

Motherboard and logic board are usually used interchangeably in most technical situations. When it comes to video cards, motherboard is technically a term of art meaning “the circuit board.” Motherboard is usually what the manufacturer refers to when they refer to “computer boards” or the circuitry inside the computer case. When talking about specific pieces of a motherboard, the terms “logic board” and “motherboard” are used interchangeably.

What does Apple call a motherboard?

Answer: The Apple logic board (or motherboard) is the central processing unit (CPU) of a Mac, which is located inside the case. The Apple logo and various other hardware components are located on the logic board. (Apple call it a Logic board)


The logic board is one of the main components in a computer. It handles all the data processing and storing and communication between the system and its components. It is also responsible for controlling the power supply. The motherboard on the other hand, is the main component that holds the circuit boards.

It is the motherboard that gives the entire system its power and allows it to communicate with the rest of the computer components.
