The ASUS X570 TUF Gaming is our favored mid-range motherboard recommendation and for good reason. It comes to the table offering extremely good value for money. This is the perfect board for PC builders who prioritize future expansion and build quality.

The first thing that struck me when viewing the ASUS TUF X570-PLUS was its striking looks. Most (sensible) people probably make features and performance their number one priorities, however, we simply couldn’t ignore how well this thing looks at the heart of an AMD build.

Looks aside though, the performance levels of this board are extremely high thanks to its 12 + 2 Phase IR Digital PWM design. Overclocking was clearly high on ASUS’s agenda when developing this product as the potential is pretty impressive.

This board has a whole bunch of cool features that we explore in more detail further down, but ultimately, it’s our runner up and is another superb product from ASUS.

The Asus Prime X570-P is truly the best of both worlds, with great performance levels and features at an affordable price tag. It’s what every consumer wants. It comes equipped with Asus’ signature build quality and overclocking potential.

This is one of Asus’ many entries into our best of guide and it’s hard to argue against its position in this guide. It comes to shelves at sub $150- a price tag we feel is incredibly good value for money. The X570 range doesn’t characteristically have many budget boards amongst its ranks. Having said that, this one certainly showcases excellent value for money at a reasonable price.

If you’re looking for a powerful motherboard that comes to shelves equipped with good features, great build quality, and is affordable, then look no further.

Best B550 Motherboard

Editor's Rating

The Asus ROG Strix B550-E offers great value for money for those stuck between the powerful X570’s and the limited B450 MAX options out there. This comes packed with a PCIe 4.0 M.2 slot, an M.2 key for Wi-Fi, overclocking capabilities, and fast RAM support.

The great thing about the B550 motherboard is it is ready to go with those newer Ryzen 3rd gen chips and boasts support for future AMD Ryzen processors too. These new B550s remove the issue that the older B450s had, you no longer need to flash the BIOS or buy a “MAX” variant to get it working

It also comes equipped with a very aesthetically pleasing design and the build quality from ASRock is excellent as usual.

Different chipsets

It’s a great way of looking at the diversity that AMD consumers have to play with and also helps cover not only premium motherboards but budget boards as well.

Hopefully, after reading this article you will have a thorough understanding of what differences you are likely to find between various boards and which ones best suit your specific needs. Similar to our best Z390 article, we have tried to separate the boards into individual categories to showcase their specific pro’s.

All of the AM4 motherboards on this list have been hand-selected for a reason. Firstly, we conducted a thorough search to discover which motherboards gamers tend to prefer while trying to balance those with the highest reviews against those with the lowest price tags.

Reviews from various manufacturers were taken into account, as well as reviews from others in the PC gaming industry.

Next, we get our hands on as many of our recommendations as possible so we can see the build quality up close.

How We Test

From CPUs to AM4 motherboards, we like to get hands-on with all the hardware we recommend. Testing the products is a huge part of our overall selection process and it is a way we can be sure that a specific option is the best for the job.

Products must pass our testing which is largely a lot of gaming, with some other boring stuff but most if not every recommendation will have gone through a strict testing process.

With motherboards regardless of the chipset, we need to assess build quality, performance, and finally, value.

This process enables us to provide you with an accurate take on how well a motherboard performs and, ultimately, if it’s worth your hard-earned cash.

Things To Consider

So above is a stripped-back, sneak peek at our list of best AM4 Socket motherboards. Now, you might be asking yourself, that’s brilliant but what actually separates these boards from one another? What should I be looking for when deciding which to choose?

They’re great questions and ones people ask regularly. We’ve decided to break down the most important aspects of the motherboard and explain what they do and why they’re important. We do this to educate you as an informed consumer is much more likely to make the correct component choice.

The following are some of the aspects of a motherboard you should be taking into consideration when researching which one to purchase.

Form Factor

atx mobo eatx

Form factor, for lack of a better word, is the physical size of the board. In this article, we cover a broad range of motherboard forms so it’s a great point to discuss the features and benefits of the main types. The most popular forms range from E-ATX (designed for PC enthusiasts looking to build the best of the best) right down to the Mini-ITX (for consumers who want a build with an extremely low footprint).

The footprint is something you need to figure out at the start of the build process. If you start a build not knowing the form factor of your board you might find at the end of the build certain components just won’t fit. Which is going to be annoying, time-consuming, and potentially costly.

Below we have put the different forms into a chart so you can compare:

Form Factor

Form FactorSize (in inches)
Mini-ITX6.7 x 6.7
Mini-ATX5.9 x 5.9
microATX9.6 x 9.6
ATX12 x 9.6
eATX12 x 13

There you have the 5 most popular motherboard form factors and their corresponding dimensions. This should clear up any confusion you may have on form factor going forward. It’s not just size that separates each of the forms though, let’s waste no time getting into the socket and chipsets.

Socket

x570 amd zen 3

There are two main types of motherboard socket, the LGA 1151 and AMD’s AM4. In this article, we’re concentrating on the AM4 socket, obviously.

The socket is the physical slot on the motherboard that holds your CPU in place. Intel has the LGA1151 and AMD has their AM4. This means AMD’s latest 3700x processor WILL NOT be compatible with any of the LGA1151 boards and vice versa.

Please never try to force the wrong processor into the incorrect socket type as it can cause fatal damage to your newly purchased components. If you’re ever unsure when putting components together always check our how to build a gaming PC article.

Why not check out our hardware compatibility article to fully understand what components pair best with each other.

Chipsets

Probably the most important factor when choosing which motherboard to start with is the chipset. The chipset, for those that are unaware, is the key factor in determining which features your motherboard comes with. The features range from PCIe lanes and SATA ports right through to overclocking support and the USB generation.

You really need to make sure you know your motherboard’s chipset before your start buying the other components or you might find yourself in a position where you’ve bought a piece of hardware that has nowhere to live or is underutilized.

Also, with technology advancements moving quicker than ever, always check to see if your specs are up-to-date. There are a number of older and cheaper boards that don’t have M.2 support or DDR4 RAM for example.

Below is a rough chart of varied motherboards and what their chipsets have to offer:

Memory

x570 motherboard memory

Memory is one of the most important hardware components you can buy when you’re putting an AMD build together. Due to the nature and build features of the Ryzen chips, the best way to maximize performance power is by equipping your build with rapid RAM.

Therefore you need to make sure your motherboard can accommodate the RAM you are wanting to pair it against. Things to be mindful of are: Max supported memorymemory speedmulti-channel support, and how many memory slots are on the board.

The easiest way to check whether your motherboard is compatible with the RAM you currently own or want to buy is in the motherboard spec’s. It will tell you straight away how much and what speed RAM it can accommodate.

Alternatively you can have a look at your hardware compatibility page which should answer most of your questions.

Particularly important when purchasing a smaller form board is the location of the memory. You’re probably asking yourself now, why would that be a problem, as long as it fits? Well, strictly speaking, the memory location is rarely going to be an issue. However, if you’re mad into overclocking you may have purchased a large, aftermarket custom CPU cooler.

In some cases, the larger than normal heat sink can become a real problem. Just make sure if you are choosing a larger cooler that the RAM is located far enough away to accommodate for both.

PCI Slots

DSC09354

Peripheral Component Interconnect, or PCI, is the physical slot in which you can expand the capabilities of your basic system.

This includes, but not limited to things like:

  • Wifi card
  • Video card
  • Extra USB ports
  • NVMe expansion cards

There are two types of PCI slots: PCI and PCI Express (PCIe). The PCIe slot is a larger, faster version of the PCI slot and usually houses your graphics card.

If you plan on having dual GPU’s running then it’s always important to make sure you have enough PCI slots. A lot of the time, manufacturers will compromise slots to reduce the price, so making sure all your cards and expansion packs are catered for should be highly prioritized.

The other thing to look for is plenty of spacing. If you’re planning on running multiple GPUs that are large, you may need PCIe slots that are further apart to allow for adequate space.

Fan Headers

And finally, we come to PWM headers, probably more popularly know as fan headers, which are the connectors between board and CPU fans. They’re important because overclocking is becoming more and more popular, meaning demand for cooling has in turn become much greater.

What does that have to do with PWM headers you ask? Well, case manufacturers are implementing more and more fans in their cases, so to make use of them all you need a certain number of PWM headers.

It’s not a massive deal in all honesty but something you should consider when buy a case with a lot of fans because a cheap board might not have the compatibility to accommodate all of them,

Pros

One of the nicest looking boards available

Built-in heat sink Fan

Great overclocking potential

Cons

Very expensive

The MSI x570 Godlike is regarded as one of the best boards you can buy with a huge amount of features to go along with its rather large price tag. This motherboard is by no means a budget option as it comes with a high-quality 14+4+1 digital power phase design, which requires a large thermal heat sink.

Design-wise it’s hard to beat the MSI Godlike. The motherboard features Mystic Light RGB with an “infinity” RGB window in the corner. The board also has a small OLED display that will show you any debug codes when things go wrong or it can display temps for hardware monitoring.

Other more functional features include the Frozr heatsink design, M.2 expansion card, and 10g ethernet card. To the back of the board, we see a clear-CMOS button which is very handy for the overclocker. This Clear-CMOS function will allow you to push your RAM to the limits without having to go into your system and try to get the CMOS battery out. Next to the SMOS button sits a BIOS flash button so you can update your BIOS without breaking a sweat.

Overall this is a superb motherboard and its onboard WIFI capability is fantastic. MSI is not messing around with the Godlike, as you can probably tell from the Gigabit jack, 2.5 Gigabit jack, and the 10g ethernet card. This board can only enhance your build!

FAQs

What Is Socket AM4 Motherboard?

AM4 is a PGA CPU socket designed especially for all AMD processors with Zen, Zen+, Zen 2, Zen 3, and Excavator microarchitecture. Basically, if you want an AMD gaming build, you’ll need a motherboard with an AM4 socket.

Released in September 2016, it was designed to be a one-stop, universal socket for new processors, rendering previous formats, AM3+, FM2+, and FS1b redundant. Featuring support for both single and dual-channel DDR4 memory, it was able to compete with Intel’s advanced sockets.

There are currently three series of chipsets under the AM4 umbrella, with eight options in total, but for gaming, you’ll most likely only need to decide between two series. Typically found in high-end boards designed for ultra-low latency gaming, the X-Series is the premium option.

The B-Series is more of a consumer-friendly option, and due to their affordability, are the most popular choice for standard gaming builds.

Is AM4 Future Proof?

AM4 has been an absolute workhorse up to present day. It supports more CPUs than you could shake a stick at. Seriously…your arm would fall off, the stick would snap, it’d be a whole thing.

As thankful as we are for AM4’s stalwart service, it has many of us wondering just how much juice it has left. Surely AMD doesn’t plan to keep churning out backward compatible CPUs forever. Eventually, something’s got to give, right?

Sadly, this is true. Just last month, AMD released the Milan iterations of their Zen 3 CPUs, most likely the final release on the AM4 format. AMD hasn’t officially announced their Zen 4 processors yet, but it’s assumed they’ll get a release at some point in 2022 alongside new AM5 socket motherboards.

This doesn’t exactly mean that AM4 isn’t future proof. A quality AM4 setup will still support all AAA games pegged for release in the foreseeable future, it just won’t be able to accommodate any new AMD CPUs. Until AMD stops producing AM4 CPUs entirely, you have nothing to worry about.

Is Zen 3 Going to Be AM4?

Zen 3 was released November 5th, 2020, and, yes, it is indeed compatible with the infamous AM4 socket; however, the only chipsets Zen 3 CPUs are compatible with are X570 and B550.

If you’re rocking an older motherboard with a different AM4 chipset, unfortunately, you won’t be able to run a new Zen 3 processor. Not to worry though, AMD warrior; all the more reason you should treat yourself to one of the first five motherboards on our list of the best AM4 motherboards.

If you’re looking to build the best AM4 board possible, we can’t speak highly enough of the MSI MEG X570 GODLIKE. Even though AMD may be moving onto greener pastures in the near future, with this mobo in your case, you’ll be prepped for years of super immersive, high performance gaming.

If a budget build’s on the cards, you can’t go wrong with the Asus ROG Strix B550 E. It looks great and comes with more than enough clout to keep the average gamer happy indefinitely.

Can AM4 Fit in AM3+?

An AMD CPU with an AM4 socket will not be compatible with an AM3+ motherboard, we’re afraid. Neither will trying to force an AM3+ CPU into an AM4 motherboard bring any good fortune.

AM3+ motherboards and CPUs are largely out of the equation now. It’s not that they’re bad for gaming. In fact, the FX-8350 is still considered to be a pretty hot CPU, but they’ve had their time in the spotlight, and now it’s all about AM4 until Zen 4 takes the world by storm.

Final Word

So, there you have it, our best AM4 motherboards of 2021, the question now is which one is most suited to your needs? Well hopefully the little category headers have helps you establish that. But if not, our in-depth reviews will have done!

The cream of the crop and our best AM4 motherboard is the Godlike from MSI. This board is going to be overkill for the majority of gamers but as a high-end solution, there are few, if any, that can compete with this board.

The runner-up is no slouch either, in fact, as far as premium motherboards go the Gigabyte X570 Aorus Master offers incredible value if you can put its features to use. This board is one of the best looking AM4 motherboards on the market and not only has incredible VRM performance but features everything you are going to need to tie your build together.
