What motherboard do I need for my Intel or AMD Ryzen CPU?

How to make sure you get the right mobo for the job

Your CPU and motherboard are the brain and nervous system of your PC, and while you can (sadly unlike a brain) swap them out to replace with better ones, there’s a lot more to this than simply slapping in some silicone. You’ll need to make sure that the two components are compatible with each other, for certain chips will only work when installed on certain motherboards. Mismatch the processor with the motherboard’s socket or an incompatible chipset, and it won’t matter if you’ve got one of the best CPUs for gaming - the only functioning component left in your build will be the case.

Take a few minutes to peruse this guide, then, and you’ll know for sure which motherboard you’ll need for your CPU. I’ve updated it to cover the latest Intel 12th Gen Alder Lake CPUs, as well as their 10th and 11th Gen models, the AMD Ryzen 3000 series, and the most recent Ryzen 5000 series.

Step 1: Choosing the right motherboard socket

Take a quick glance at any CPU and you’ll probably see it’s got a heck of a lot of pins (if it’s AMD) or tiny little contact points (if it’s Intel) on the bottom. These are what slot into your motherboard’s CPU socket, so you’ll need to buy one that fits correctly. If you try and stuff one into the wrong kind of motherboard socket, all you’re going to end up with is a load of bent pins and some very broken components.

An Intel LGA 1200 socket. Upwards-facing pins make contact with tiny plates on the CPU.

Intel’s 12th Gen Alder Lake chips use a brand-new LGA 1700 socket, which is slightly taller than the LGA 1200 socket used by the 11th Gen Rocket Lake and 10th Gen Comet Lake CPUs. AMD’s Ryzen chips consistent use the AM4 socket.

There are some exceptions when getting into workstation hardware or enthusiast-grade chips: AMD’s Threadripper processors fit in the TR4 socket, while some Intel chips use the LGA 2066 socket. You probably don’t need to worry about these ones, mind – assuming you’re building a gaming PC, chips that use the LGA 1700, LGA 1200, or AM4 socket will be plenty powerful and much more cost-efficient.

Previous Intel generations used the LGA 1151 socket, which you might need to look out for if you’re cutting costs by opting for one of their older 8th / 9th Gen Coffee Lake CPUs, but here we’re going to focus on the most recent hardware. Speaking of which, here are all the Intel 12th Gen chips that will slot into the LGA 1700 socket:

Core i3 Core i5 Core i7 Core i9 Other
Core i3-12300 Core i5-12600K Core i7-12700K Core i9-12900K Pentium Gold G7400
Core i3-12300T Core i5-12600KF Core i7-12700KF Core i9-12900KF Pentium Gold G4700T

By contrast, AMD has stuck with its AM4 socket ever since their first generation of Ryzen 1000 chips. That said, newer CPUs won’t always work on older motherboards due to incompatible chipsets, but more on that shortly. Here's what an AM4 socket looks like in the flesh:

In any event, it’s best to stick with Ryzen 3000 and 5000 processors if you’re planning a new build - Ryzen 4000 chips aren’t sold individually - so here’s a list of all those AM4-friendly parts.

Ryzen 3 Ryzen 5 Ryzen 7 Ryzen 9
Ryzen 3 3300X Ryzen 5 5600X Ryzen 7 5800X Ryzen 9 5950X
Ryzen 3 3100 Ryzen 5 5600G Ryzen 7 5700G Ryzen 9 5900X
Ryzen 5 3600XT Ryzen 7 3800XT Ryzen 9 3950X
Ryzen 5 3600X Ryzen 7 3800X Ryzen 9 3900XT
Ryzen 5 3600 Ryzen 7 3700X Ryzen 9 3900X

Step 2: Choosing the right chipset

So we’ve narrowed down the type of motherboard socket you need. The next thing is deciding which chipset to go for. This is the circuitry inside the motherboard itself. Without going into too much technical detail, a motherboard’s chipset essentially determines what kind of features it has, including the types of ports and storage connectivity it provides. They’re also usually designed to work with a particular family of processors, and often get released around the same time as their corresponding CPU family.

Intel in particular like to make things complicated, always launching new chipset series alongside new CPU generations. The most recent of these is the 600 series, which initially consisted entirely of the Z690 chipset before lower-spec, cheaper alternatives launched early in 2022. You can see in the table below which Intel chipsets are compatible with which Intel CPUs:

Chipset 10th Gen Comet Lake 11th Gen Rocket Lake 12th Gen Alder Lake
Z690 X X Yes
H670 X X Yes
B660 X X Yes
H610 X X Yes
Z590 Yes Yes X
H570 Yes Yes X
B560 Yes Yes X
H510 Yes Yes X
Z490 Yes Yes (may not support PCIe 4.0) X
H470 Yes Yes (may not support PCIe 4.0) X
B460 Yes X X
H410 Yes X X

As for AMD, the latest Ryzen 5000 processors didn’t launch with an all-new chipset: they were designed for AMD’s existing 500 series chipsets, which already worked with the Ryzen 3000 family. They're also compatible with some older 400 series chipsets after a BIOS update, but this will vary between motherboards and manufacturers, so be sure to check it definitely has Ryzen 5000 support before you buy.

In other words, you won’t necessarily need to swap out your existing AM4 motherboard if you’re upgrading from Ryzen 3000 to Ryzen 5000, but for most 5000 adopters it’s probably easier to just buy a 500 series board. Here's how the Ryzen chips work with the Ryzen chipsets:

Chipset Ryzen 3000 Ryzen 5000
X570 Yes Yes
B550 Yes Yes
A520 Yes Yes
X470 Yes Selective Beta BIOS update needed
B450 Yes Selective Beta BIOS update needed
X370 Selective Beta BIOS update needed X
B350 Selective Beta BIOS update needed X

Intel motherboard chipsets explained

At this point you might know which chipsets work with your CPU in a general sense, but there aren’t multiple chipsets in a series just for funsies. Each one targets a different level of functionality and pricing, so you can tailor you motherboard choice to fit your budget and need for specific features.

In Intel’s case, the most decked-out motherboard chipsets always start with a Z: Z490, Z590 and Z690 being the most recent. These will always support CPU overclocking (though some B560, H570 and B460 boards allow overclocking too), and they also have the most PCIe lanes. This means you can install more PCIe devices (like NVMe SSDs) than the other, cheaper chipsets. Higher-end motherboards also have a wider range of USB ports and better RAID support for multiple storage drives.

That said, affordable chipsets like B570 and B600 have enough of these lanes to adequately equip most PC gaming builds, so they can also work well. To give an idea of price differences, here are how a few of Intel’s chipsets compare:

It’s worth noting that if you want to install a superfast PCIe 4.0 SSD, you’ll need at least a 500 series chipset and Rocket Lake chip. The newer 12th Gen hardware also supports PCIe 5.0, though don’t expect hardware that can actually use the extra performance to arrive any time soon. In the meantime, you can find some quality 4.0 picks on our best SSDs for gaming list.

Some chipsets will dictate the size of the motherboard in addition to features. A mini-ITX motherboard (left) is much smaller than an ATX motherboard (right), so make sure you get the right one for your case.
One last note about Intel motherboards, specifically those 600 series models designed for Alder Lake: the CPUs will be able to support both DDR4 and DDR5 RAM, but each motherboard will only be compatible with one or the other. So get a DDR4-compatible mobo if you want to stick with current-gen memory, or get a DDR5-ready motherboard if you're willing to upgrade your RAM as well. So far, mind, there's not much difference between DDR4 and DDR5 for gaming performance.

AMD motherboard chipsets explained

Most of AMD’s chipsets enable overclocking, save for the A520 and the increasingly obsolete A320, so if OC capability is a must for you, there’s a little more choice to be had than with Intel. Even so, there are also benefits to going upmarket: X570 supplies more SATA sockets and USB ports than B550, which in turn supports more than A520.

More ambitious PC builds would therefore do well to stick with a higher class of X series AMD chipset, and conversely, those with very simple storage setups can get by with the mid-range B series or entry-level A series chipsets. Here’s how the Red Team options currently stack up on cost:

Anything else I should know?

From there, it’s pretty much up to you what kind of extra features you go for. Some motherboards like the Gigabyte X570 Aorus Master have additional overclocking tools, such as an LED troubleshooting display and onboard power/reset buttons, while many more include pre-mounted I/O boards for a neater finish round the back of your PC.

It probably goes without saying that you should also pick a motherboard that actually fits inside your intended case. There’s no point buying an ATX-sized motherboard when you’ve got a small form-factor or mini-tower case, nor is there much sense in buying a jumbo full tower case for a tiddly mini-ITX motherboard.

As to whether PCIe 4.0 support is a must-have… I’d say not at this exact moment, mainly because you can get some excellent PCIe 3.0 SSDs (like the WD Blue SN570) that are plenty fast enough. Both 3.0 and 4.0 SSDs will also be able to play nice with DirectStorage, an exciting piece of Microsoft tech that could see loading times in games slashed to ribbons. It’s not actually supported in any games yet, but you won’t have to base your motherboard choice on it.

Of course, PCIe 4.0 is still faster in general, and if you’ve buying an Intel 12th Gen Alder Lake CPU, your should get 4.0 support as standard, whatever motherboard you pair it with.
