Logic Board vs. Motherboard: What’s The Difference

If you’re in the market for a new computer, it might be a little tricky to know that there’s more than one type of computer board inside your machine.

With so many different types, it cannot be easy to decide which is best for you. In this article, we’re going to explain to you what’s the difference between these two boards and help you decide which is better for your needs.

What is a Logic Board, and where is it located on your computer?

A logic board is a mainboard that houses all the components of your computer, such as the processor, memory, graphics, and storage.

It’s usually located near the CPU or northbridge in a desktop computer and is also common in laptop computers. A motherboard usually has more than one logic board in it.

What is a Motherboard, and how many types are there?

A motherboard is the central part of a computer system, containing all of the circuitry that allows the individual components to work together. A motherboard can be made of many materials, but metal or plastic are the most common ones.

Most motherboards come with at least one expansion slot, a port that allows you to connect additional peripherals (such as printers or storage devices), and a USB port. 

But the most common ones are called micro-ATX, ATX, and E-ATX. Micro-ATX motherboards are typically used in home computers and have a smaller form factor than ATX or E-ATX boards.

ATX motherboards are used in office and industrial PCs and have a larger form factor than micro-ATX boards. E-ATX motherboards are designed for high-performance servers with the largest form factor available.

What’s the difference between a Logic Board and a Motherboard?

A motherboard is the heart of a PC. It contains all the components that allow your computer to function, including the processor, memory, graphics card, and other ports.

A logic board is simply a board attaches to a motherboard, providing additional functionality such as audio and USB ports.

How do you upgrade the Logic Board on your computer?

Upgrading your computer’s Logic Board is a simple but important task that can improve your system’s performance. A logic board is the main component of a computer, and it contains all of the system’s essential circuitry.

Upgrading your logic board can resolve computer issues like slow performance or errors. Here are instructions on how to upgrade your logic board:

  1. Remove the computer’s battery if it is not being used.
  2. Locate the screws that hold the logic board in place (two on each side). Use a Phillips screwdriver to remove them.
  3. Gently pull the logic board out of the casing. Be careful not to damage it.
  4. Place the new logic board in place and re-install the screws. Make sure you line up the black marks on the new board with those on the casing.
  5. Replace any damaged components on the old logic board before reinstalling them into the casing.

Similarities between these two computer parts

Computer parts that are typically compared are the logic board and motherboard. Both are essential for a functioning computer, but they serve different purposes.

A motherboard is responsible for all the electrical connections in a computer and helps control the information flow between the different parts.

Logic boards contain the processors, memory, storage devices, and other components necessary to run a computer. They have connectors that can be attached to motherboards and other components. 

Logic boards and motherboards share some similarities but also significant differences. For example, both logic boards and motherboards come in different sizes, but motherboard sizes vary more than logic board sizes.

Motherboard types also differ, with ATX being the most common type of motherboard used in PCs. In contrast, most logic boards use smaller form-factor motherboards (SFF).

Another similarity between these two parts is that both can be damaged if not properly protected. Finally, while motherboards generally have longer warranties than logic boards, there are exceptions to this rule.

Computer Parts: Logic Board vs. Motherboard

What’s the difference between a logic board and a motherboard? Here’s a look at each component and how they work together in a computer. 

Logic Board 

A logic board is a PC’s main “brain,” responsible for carrying out instructions from the CPU (central processing unit) and other components. It’s typically made up of sensors, chips, and connectors that allow it to communicate with other computer parts. 


A motherboard is essentially the same as a logic board but usually comes pre-installed with other components like graphics cards, memory, and storage drives. It also houses all the connections for those parts, providing power to them.

What are the Features of a motherboard?

A motherboard is the primary component of a computer system. It contains all the components necessary to connect the various devices in your computers, such as the CPU, RAM, graphics card, and other peripherals.

The motherboard also controls which devices can access which ports on the CPU and provides power to all the other components.

The most important feature of a motherboard is its connection potential. A good motherboard will have multiple connections for your CPU (the central processing unit), including PCIe (Peripheral Component Interconnect Express) lanes and USB 3.0 ports.

This allows you to attach multiple graphics cards, hard drives, and other peripheral devices to your computer without worrying about bottlenecking any section.

Additionally, a good motherboard will have plenty of serial ATA (SATA) ports for loading your hard drive with data or installing an operating system.

In addition to its connectivity features, a good motherboard will also include features specific to your particular computer system or configuration.

For example, some motherboards include Ethernet connections to easily share files between different parts of your home or office network.

Other motherboards might include built-in Wi-Fi antennas so you can easily connect wirelessly to nearby networks without purchasing additional hardware.

Ultimately, what makes a great motherboard is not simply its quantity but its quality as well. Make sure you research each board before purchasing to get exactly.

What are the Features of Logic Board 

A motherboard is a circuitry that connects all your devices, including the processor, RAM, graphics, storage, and other peripherals. Many modern computers have a built-in motherboard.

A logic board is a separate component that houses your computer’s processors and other circuitry. They come in different shapes and sizes depending on the make and model of your computer.

They generally have more connectors than a motherboard, which makes them better suited for upgrading or replacing your computer’s components.

Pros & Cons of  Logic Board 

Logic boards are a newer type of motherboard that is becoming more popular. They are different than motherboards because they have a separate logic board that contains all the components necessary for computing, such as processors, memory, and storage.

Logic boards typically cost more than motherboards but may offer performance advantages.

One advantage of using a logic board is that it can be upgraded or replaced separately from the rest of the computer. This allows you to upgrade the processor or memory without replacing the entire motherboard.
