Logic Board Vs. Motherboard

Logic Board Vs. Motherboard

Ask me what a logic board is, and I’d first tell you about the motherboard. In layman’s terms, a mobo or a motherboard is the main component in a computer to which every other internal part is connected.

However, the logic board isn’t much different from the regular mainboard. The logic board and Mobo can now be utilized interchangeably, but there was a time when these two used to have a little prominent difference. For explaining it further, let’s get you through the peculiar information of logic board vs. motherboard.



Motherboard, sometimes called the system board, is the core circuit board of your system unit. A lot of electronic parts attach to your motherboard; others are built into it. A current desktop personal PC motherboard comes with slots for adapter cards, memory, and the processor chip.

Memory chips are installed on the memory cards (modules) that fit in the slot on your motherboard. A computer chip is actually a small semiconducting material piece, frequently silicon, on which integrated circuits are installed.

The integrated circuit has a lot of microscopic pathways able to carry electrical current. Every integrated circuit can have millions of elements like capacitors, resistors, and transistors; specific processor types, memory, and other chips.

Logic Board:

It’s also the main component of the Computer Board which was actually introduced by apple; it has the internal circuitry of your PCs. You can say that it is an internal and significant part of Apple Computers.

A few Apple PCs also had logic board issues as they generate some sort of sound from inside your system unit. And MacBook Pro is the PC that is generally having Logic Board issues. But Apple provided its users to replace the logic board for free when they brought the unit in for fixing.

Is The Logic Board And Motherboard The Same Thing?

Motherboard and logic board, however similar in usage, can’t be considered indistinguishable, at least throughout the period when logic boards would be utilized mainly for Mac PCs. The primary disparity between main circuit boards in the early 80s and logic boards of that period is in the parts that are to be connected to such boards.

The older Macs that utilized Motorola processors wouldn’t accept Intel processors. However, it’s been made easier with the modern Macs utilizing standard technologies that can be interchanged with equal computer parts.

One example of it is the graphic card that might need firmware to be compatible with the specific operating system. In such situations, the card can physically be connected to both logic boards and mobo, but not necessarily work properly for both the PCs.

The baseboard can simply be purchased online or from a shop near you, making it pretty easy to upgrade the PCs with a new planar board at a lower price. The logic boards are created by Apple and are created for particular Mac models. Logic boards can be purchased online as well, but it’s quite pricey to change them, and one usually would not pick this route.

Is A Logic Board A Motherboard?

These are the only notable differences you can locate between a mobo and a logic board. Well, that is all in the past, when you’d require Logic boards for particular Macintosh models. Over time, such logic boards and system boards have evolved to the extent that they can be utilized interchangeably and can also be regarded as one. You can say that a logic board is simply a fancier name for the main circuit board.


The logic board is simply a terminology specific to Macintosh PCs that did not lose the charm over the past years and is still utilized for Apple’s main circuit boards. Motherboards and logic boards have the same purpose for a PC and are technically the same. Call it whatever you may, mainboard, motherboard, main circuit board, system board, planar board, baseboard, a mobo, or logic board; these all denote the same thing.
