What CPUs are compatible with my Motherboard?

If you’ve decided to build your personal computer, you must check a bunch of factors to effectively meet the expectations. In addition, selecting the correct type of processor is one of the most crucial aspects since it supervises the overall rig’s performance. Building your computer system can be a fun, rewarding, and cost-effective activity that you haven’t experienced before.

At the same time, it can be perplexing and overwhelming for some. After all, considering how much a brand new rig costs, no one wants to ruin it. The main concern for new builders is PC component compatibility. With a bit of research, compatibility can often be overcome, and anyone building a PC for the first time should always look into CPU and motherboard compatibility first. So let’s see what CPUs are compatible with my motherboard?

Socket model

To determine whether your CPU is compatible with your motherboard, you must first select the socket model. Specific socket requirements for each CPU can be found in their specifications. The LGA1200 socket is required by the latest Intel 10th and 11th Gen desktop CPUs, while the AMD Ryzen 1000, 2000, 3000, 4000, and 5000 series desktop processors require the AM4 socket.

When you look up the motherboard specifications online, you will notice that they do not include all of the supported CPU models. They will instead only mention the CPU socket they have. You can use this socket information to determine which CPU models the motherboard will support. The motherboard’s socket is also significant for the chipset. The chipset controls many aspects of the motherboard, including the socket.

Working out which CPU will work with my motherboard

The first decision you must make is which processor and motherboard to use. These two components are inextricably linked and are the deciding factor in the rest of your build’s compatibility. Aside from size, many other parts have a more comprehensive range of suitability than a processor, unless you’re dealing with very old models, so this factor often becomes the driving force behind your entire build.

In general, there are two main processor lines to choose from when building a gaming PC: AMD’s Ryzen and Intel’s Core. For the foreseeable future, the Ryzen line has been made fully forward and backward compatible (and it only started in 2017, so you shouldn’t have to worry about that changing anytime soon). It is also true for the latest Ryzen 5000 series processors, which have a wide range of support from the X570 and B550 chipsets, with more than 400 series support.

What exactly is the CPU socket?

As the name implies, a CPU socket is a physical mount on which the processor is installed. It essentially provides the necessary mechanical and physical dimensions and the pin layout to facilitate CPU connectivity with the motherboard. Simply put, it is the location of the CPU on the motherboard. If your CPU socket is incompatible with your motherboard, it will certainly not fit in the mount.

To ensure that your motherboard is compatible, check what socket and chipset your processor supports. The socket is the physical slot on the motherboard that houses your processor. It should be simple to figure out by looking up the socket size for both the processor and motherboard you intend to use. You can damage the processor and/or motherboard if you try to pair it with the wrong socket type.

Surface mounting techniques and types of sockets

Essentially, there are three types of mounting methods for CPUs:

  • LGA: Land Grid Array
  • PGA: Pin Grid Array
  • BGA: Ball Grid Array

LGA: Land Grid Array

A land grid array (LGA) is a printed circuit board design consisting of a square grid of contacts connected to other components. The term refers to a “socket design,” in which certain elements are separated from the actual circuit board and integrated into the board’s structure in novel ways. Unlike most other designs, LGA configurations have pins in the socket rather than on the chip.

PGA: Pin Grid Array

The integrated circuit packaging standard used in most second- through fifth-generation processors is a pin grid array (PGA). The rectangular or square pin grid array packages had pins arranged in a regular array. Pin grid array was preferred over dual in-line pins for processors with larger data buses because it could better handle the required number of connections.

BGA: Ball Grid Array

Ball Grid Array is abbreviated as BGA. This is an array of small-sized / tiny metallic conductor balls that are arranged in a harmonious form on the Board that we use to make a PCB in its most basic form. Companies (manufacturers) have formed due to increased demand for only BGAs (Example- Xilinx). These balls will eventually be used to make connections using small and precise soldering while assembling microprocessors and integrated circuits to complete the circuit we intend to build.

Confirming compatibility with the motherboard chipset

While the socket is the most crucial consideration when determining CPU and motherboard compatibility, the motherboard chipset is also important. It is because, in most cases, the socket remains consistent across chipset generations. It may cause some compatibility issues, which can usually be resolved by updating the BIOS. The AMD B350, AMD B450, and the newer AMD B550 motherboard chipsets, for example, all use the AM4 socket.

The AMD B550 was released in June 2020, a few months before AMD’s Ryzen 5000 series CPUs. As a result, the B550 motherboards can quickly run AMD Ryzen 5000 series CPUs without the need for a BIOS update. Despite having the supported socket, the older B350 motherboard would not be able to run the 5000 series processor by default. Instead, a BIOS update will be required.


If I conclude at the end, the simplest answer to the question “what CPUs are compatible with my motherboard” is to figure out what socket it supports and then look for a motherboard that supports that socket. Sockets are also shared among different generations of motherboard chipsets. So it’s generally a good idea to keep the chipsets in check so that you might have maximum performance. If you plan to use a CPU from the latest generation, we recommend getting the latest motherboard chipset series.
