What’s the Best AM4 Motherboard in 2021?

Have you landed a great Ryzen processor, and now you need the right motherboard?

Well, AM4 is your best bet. It’s the most popular socket, supports a whole range of chipsets, and best of all, it’s future-proof: AMD has promised long-term support.

Check out our guide to the best AM4 motherboards for every budget and purpose whether you’re a gamer, video editor or streamer.

What Makes a Good AM4 Motherboard?


Motherboards are all about compatibility. Motherboards have different chipsets, but AMD’s are way more forgiving than Intels.

You also want to check it supports your RAM and it’s got enough PCIe slots, memory slots and ports, taking into account any extras you might want to add later.

Finally, think about casing; make sure it can actually fit into your case.


There’s 3 main sizes (or to use the more technical term, form factors) of motherboard: ATX is the largest and most ‘standard’ size, Micro-ATX is smaller and Mini-ITX is the smallest. (I know, you would think Micro would be the smallest but it isn’t).

Generally, the bigger the board, the better; it will have more features, and more connectors, heatsinks, card expansion slots, and RAM slots.

Micro and Mini have to inevitably make some pretty large sacrifices, and you’re never going to get as good value as an ATX board, so we recommend ATX if you can swing it.

How We Choose AM4 Motherboards

Features and Performance

Although specs are important, real-life testing is even better. For example, gaming benchmarks, overclocking testing, and efficiency all paint a much better picture of performance.


We always bear the user purpose in mind, instead of just going for the highest specs. You don’t want to overspend for nothing.

Value for money

The price has to be reasonable, but even more importantly, can you get more for your money elsewhere?

  • Gen2 M.2 slot


If you’re looking to use a AMD Ryzen 3rd or 2nd Generation chip such as the quality Ryzen 7 2700 or 3700X, this is the best motherboard sporting the latest AMD X570 chipset.

It delivers great performance, stability and overclocking, topped up with an attractive design and expandability options.

This model holds its own against more expensive X570 boards, the only major difference between losing 2.5G network capabilities and 2 less SATA ports.

It’s a very well-rounded board with 3 M.2 slots, premium audio, wifi, a quiet fan and plenty of USB slots.

It’s also backward-compatible with Ryzen 1000 series and other AM4-socket processors.

Memory is DDR4 with speeds up to DDR4 4400, with up to 128GB over 4 RAM slots and 6 SATA ports.

There’s plenty of fast USB connectivity with 10 USB ports, including 3 USB 3.2 Gen 2 ports (one Type-C).

It uses a premium Realtek ALC1220-VB audio codec.

The voltage regulator heatsinks are a bit revolutionary, with a direct-touch heatpipe and a fin design that increases heat dissipation area by 300%.

There are 3 full-length PCIe 4.0 slots, the top 2 of which are reinforced, supporting two-way SLI and up to three-way CrossFire multi-graphics card configuration.

Gaming performance was similar to other more expensive X570 models (Crosshair VIII’s 64W and ASRock Phantom Gaming) when playing Ashes of the Singularity: Escalation.

It overclocks well with no issues and no overheating, similar to more expensive X570 boards.

It’s also 12% more efficient than a few other X570 models, and temperatures peaked at just 148W, lower than Crosshair VIII’s 64W and the ASRock Phantom Gaming’s 218W.

RGB lighting is more subtle than some, on the left voltage regulator heatsink and audio section, though it does come with a few headers if you want to add more.

Honorable Mentions:
