In our series of motherboard buyers guides, here’s the latest update to our list of recommended AMD motherboards. All numbers in the text are updated to reflect pricing at the time of writing.

Best AMD Motherboards: September 2020

It is no secret that AMD has had a good couple of years with its Zen and Zen 2 architectures, and the next-generation Zen 3 is hyped plenty as a future platform to move to. There's still a bit of time until AMD unveils its next-gen Ryzen series and with it looking likely to hit shelves this year, all the attention is still on Ryzen 3000, which was recently refreshed with the addition of several 'XT' processors.

Looking at another competitive Q3 2020 for AMD, we highlight our best motherboard choices for September 2020 based on AMD models currently available, with some alternations compared to our previous guide for July. Both B550 and X570 dominate the selections with support for PCIe 4.0.

AMD Motherboards Recommendations
September 2020
AnandTech Motherboard Amazon Newegg MSRP
Money No Object GIGABYTE X570 Aorus Xtreme - $700 $700
Sweet Spot ASUS ROG Strix B550-F Gaming Wi-Fi $205 $205 $210
Value Choice ASRock B550 Phantom Gaming 4/AC $125 $125 -
Mini-ITX GIGABYTE B550I Aorus Pro AX - $180 $180

Our recommendations for motherboards are based entirely on my personal and professional opinion. There are notably a large number of different motherboards across the AMD chipsets including B450, X570 and more recently, B550, so I selected my top four picks based on the four market segments. Much of our attention is on consumer desktop boards (socket AM4), though we are well aware of the benefits of TRX40 and Threadripper. We may look to include a HEDT based segment going forward in future guides if there is interest from our readership to include it.

As Coronavirus restrictions begin to lift in certain regions, the pandemic is still causing an effect within the industry. The impact that the Coronavirus has had on pricing has been considered in the guide as well, with some fluctuation on hardware pricing already taking hold. Some boards from our previous picks (July 2020) have had stock issues, so we've adjusted our guide slightly to accommodate for this. It's also worth noting that B550 is generally considered the budget AM4 platform, but the pricing has been a little topsy-turvy with some boards reaching (and even surpassing) the prices of low-end X570 boards. AMD has also recently announced its entry-level A520 chipset, with some very price conscientious models to select from. All of these points have been taken into consideration in our September 2020 guide for the AMD selections.

For users looking for other options, we've also gone over multiple chipset families as well in the links below.

Money Is No Object

GIGABYTE X570 Aorus Xtreme ($700 at Newegg)

We've had the chance to review and analyze quite a few X570 boards to date, but one of the standout boards that piqued our interest during testing was the GIGABYTE X570 Aorus Xtreme, which is the only X570 board to include a passively-cooled chipset heatsink. So for our money is no object selection, there isn't a more well-rounded X570 flagship than GIGABYTE's board. What made the X570 Aorus Xtreme stand out, however, came in our power delivery thermal testing, which showed how far GIGABYTE has come in its power delivery implementation and design. With a true 14-phase power delivery for the CPU with the Infineon XDPE132G5C spearheading the design, we saw excellent performance, overclocking, and efficiency.

The GIGABYTE X570 Aorus Xtreme Motherboard Review: Fanless AM4

The E-ATX board has a high-end feature set in line with its price. In terms of networking support, the board includes an Aquantia AQC107 10 G Ethernet controller, an Intel I211-AT Gigabit controller, and an Intel AX200 Wi-Fi 6 + BT 5.0 wireless interface. For storage, there are three PCIe 4.0 x4 slots and six SATA ports that support RAID 0, 1, and 10, as well as support for up to DDR4-4400 and 128 GB across four memory slots. A Realtek ALC1220-VB HD audio codec powers the rear panel audio, while an ESS Sabre 9218 DAC helps to bolster the quality of the front panel audio. 

 

The GIGABYTE X570 Aorus Xtreme also has dual BIOS support, which is handy for BIOS Flashback and allows one to be used for extreme overclocking, while the other could be used for more stable 24/7 settings. Focusing more on the Xtreme element, GIGABYTE also includes an overclockers toolkit with a power button, reset button, voltage measurement points for better accuracy, and an OC PEG power connector.

With a current price tag of $700 at Newegg, it's not a board for those with shallow pockets. It's also one of the best X570 and AM4 based models currently on the market from a performance perspective. For the few who can justify a $700 board, the GIGABYTE X570 Aorus Xtreme offers a robust premium feature set, looks good with its full cover thermal armor, and it offers highly efficient and reliable power delivery. In other words, it ticks the majority of boxes for both enthusiasts and gamers looking for a high-end foundation for a powerful gaming system.

There are other flagships such as the MSI MEG X570 Godlike ($700), and the ASUS ROG Crosshair VIII Formula ($700), but neither has a true 16-phase (14+2) power delivery design, and our testing shows its efficiency in reducing temperatures. Couple that in with the recent release of AMD's 16-core Ryzen 9 3950X processor, it makes the GIGABYTE X570 Aorus Xtreme our money no object selection for team AMD models.

Best Sweet Spot

ASUS ROG Strix B550-F Gaming Wi-Fi ($205 at Amazon/$205 at Newegg)

Moving onto our gaming pick for our AMD selections, and we've opted for a board with plenty of functionality and features, while also benefiting from PCIe 4.0 devices. Boards based on the B550 chipset offer partial PCIe 4.0 support, with Ryzen CPUs driving both a single full-length PCIe x16 slot as well as a PCIe x4 M.2 slot at PCIe 4.0 speeds. One of the best B550 boards we've seen to reviewed to date is the ASUS ROG Strix B550-F Gaming WIFI, a higher-end B550 board that received our recommended by AnandTech award.

The ASUS ROG Strix B550-F Gaming Wi-Fi Motherboard Review: Premium Value

What makes it our pick over the swathes of X570 and other B550 models currently available on the market is its solid level of quality and performance offered at a very competitive price point. It includes two PCIe M.2 slots, with the top slot operating at PCIe 4.0 x4, and the second slot at PCIe 3.0 x4. It uses a full-length PCIe 4.0 x16 slot which is driven from the CPU at the top of the PCIe area, while the bottom full-length PCIe slot is electronically locked down to PCIe 3.0 x4, with three PCIe 3.0 x1 slots also controlled by the chipset. The ASUS model also benefits from a stacked rear panel with two USB 3.2 G2 ports (Type A/C), DisplayPort and HDMI video outputs (for use when Ryzen 4000 APU's finally launch), as well as capability to install up to six fans.

 

The ASUS ROG Strix B550-F Gaming Wi-Fi includes an Intel-based networking pairing, with a premium 2.5 GbE Ethernet controller and Wi-Fi 6 interface. The onboard audio is also premium with ASUS's tweaked SupremeFX S1200A HD audio codec taking care of business. There are also four memory slots with support for up to DDR4-5100 which is impressive, with a maximum capacity of 128 GB. For a mid-range model, this is a stack of features, and considering similarly priced X570 models (sub $250) that include a similar controller set are non-existent, it puts the ASUS model in good standing. 

 

Touching more on the competition, thanks to a price reduction at Amazon, the B550-F Gaming Wi-Fi is $205, and at present is looking to be the best ATX sized AM4 option in this price range. The MSI B550 Gaming Carbon is more expensive with a similar feature set at $220, while the GIGABYTE B550 Aorus Pro AC can be had for around $190. Having seen the ASUS model on our test bench, and its superb performance in out of the box DPC latency, competitive CPU and gaming performance, and its efficiently cooled 14-phase power delivery, the ROG Strix B550-F Gaming Wi-Fi is our mid-range pick.

The Value Option

ASRock B550 Phantom Gaming 4/AC ($125 at Amazon/$125 at Newegg)

In previous guides, the value options have been B450 models, due to the inflating pricing of B550. However, the B450 range seems to be reducing in stock, causing prices to increase, and so we've chosed ASRock's B550 Phantom Gaming 4/AC, which represents AM4's entry-level gaming series as well as PCIe 4.0. 

One of the cheapest B550 boards, ASRock's B550 Phantom Gaming 4/AC offers a competitive entry-level feature set. The board comes with just one PCIe 4.0 x4 M.2 slot, but augments that with four SATA ports, which is plenty of capacity for game storage. The top full-length PCIe 4.0 slot operates at x16, while the bottom slot is locked to PCIe 3.0 x4, which controlled by the chipset, along with two additional PCIe 3.0 x1 slots. For networking it's using a standard Realtek based Gigabit Ethernet controller, along with an Intel Wi-Fi 5 interface . It's pretty standard for an entry-level model that focuses more on overall support, than adding extra cost at the expense of premium controllers. The B550 Phantom Gaming 4/AC is also using a Realtek ALC1200 HD audio codec, but with just three 3.5 mm audio jacks on the rear panel, as well as a basic 8-phase power delivery.

The ASRock B550 Phantom Gaming 4/AC is currently available for $125 at both Amazon and Newegg, with a non-Wi-Fi version of the board available for a slightly lower price of $115. This adds some flexibility for users looking to save a little on a feature that might not be utilized. Otherwise, looking at the bigger picture, the majority of competition from the launch-wave of A520 boards are micro-ATX boards with limited expansion options. Meanwhile the biggest competition from the X570 product stack is arguably ASRock's own X570 Phantom Gaming 4S model, which is currently available at Newegg for $140. This offers better future-proofing with more PCIe 4.0 support, as well as eight SATA ports, but it also includes a single M.2 slot and isn't with any wireless capabilities, so the B550 version gets our vote on price alone.

Mini-ITX Choice To Consider

GIGABYTE B550I Aorus Pro AX ($180 at Amazon/$180 at Newegg)

There are an impressive array of Mini-ITX AMD boards to choose from. Our pick for the best mini-ITX motherboard at present remains unchanged, and that is GIGABYTE B550I Aorus Pro AX. The Aorus Pro AX represents a solid premium offering, with official PCIe 4.0 support, two PCIe x4 M.2 slots, a Realtek 2.5 G Ethernet controller, and an Intel Wi-Fi 6 interface, all at a solid price point. 

The GIGABYTE B550I Aorus Pro AX also includes four straight-angled SATA ports, with one PCIe 4.0 x4 M.2 slot, and an additional PCIe 3.0 x4 M.2 slot, with a full-length PCIe 4.0 x16 slot. One of the interesting benefits when comparing GIGABYTE's X570 and B550 mini-ITX boards is that for the most part, both include a similar level of PCIe 4.0 support with a full-length PCIe 4.0 x16 slot. Often the only notable difference is that the B550 board only has one PCIe 4.0 x4 M.2 slot, while the other slots are PCIe Gen 3. In terms of power, the GIGABYTE B550I Aorus Pro AX has a direct 8-phase power delivery with eight premium Intersil ISL99390 90 A power stages and is controlled by an ISL229004 PWM controller. This is impressive not only for a mini-ITX motherboard, but one designed for the budget (or supposed budget) B550 chipset. 

Focusing on connectivity, this board has dual HDMI 2.0 outputs as well as DisplayPort 1.4, a single Realtek RTL8125BG 2.5 GbE controlled Ethernet port, and an Intel AX200 Wi-Fi 6 interface. There are also plenty of USB ports to make use of, with one USB 3.2 G2 Type-C, one USB 3.2 G2 Type-A, and four USB 3.2 G1 Type-A ports, as well as a handily located Q-Flash firmware update button. In an upgrade to supported memory for B550, the B550I Aorus Pro AX also supports up to DDR4-5300 memory.

 

The GIGABYTE B550I Aorus Pro AX has an MSRP of $180 and is currently available at both Amazon and Newegg. On the whole, GIGABYTE's board has the right blend of premium features to be useful, while still coming in at a price under ASRock's $200 premium B550 ITX board, or ASUS's also-$200 B550 mini-ITX offering. Out of all of the AM4 mini-ITX models on the market, some X570 models include Thunderbolt 3 – notably the ASRock X570 Phantom Gaming-ITX/TB3 – but it does cost more with an MSRP of $240. Overall the GIGABYTE B550I Aorus Pro AX is our top mini-ITX pick out of all the AMD AM4 models when taking quality, feature set, and pricing into consideration.

    Wait for Zen 3. Reply

    Keeping fingers crossed on that one, 10/08/20. But unless they immediately flood the market with newer CPU's, likely Q1 2021 for reasonable availability. Reply

    Just about to buy a CPU, probably a 3600 and sadly I agree. AMD desktop sales are sky high at the moment, they have no reason at all to release a Zen 3 version of the 3600. Financially, the wise thing to do would be to focus on extending their reach in other sectors eg TR or laptop, and only update the 3600(XT) once intel starts coming back on desktop sales.

    One can only hope. Maybe they’ll follow the Apple strategy of rapid updates of their best selling ranges to draw even further ahead of the rest of the market. It works for Apple after all.

    Based on the Zen 2 introduction, Zen 3 won't necessarily have a better price/performance ratio than Zen 2. Intel tends to hold prices constant, so that the price/performance ratio improves when they introduce a new generation of products. AMD's strategy seems to be to reduce prices over time, so improvements in price/performance ratios don't necessarily occur at the same time as new product introductions. Reply

    For those wanting Rackmounted powerhouse boards check out ASRock Rack.
    Still waiting for mine but I’ve got a few ASRock workstation/server boards for Intel.

    I’m going to love a 1U AMD Cezanne.
    Pretty soon Christmas shopping will have killer PCI 3.0 deals.
    PCI 4.0 looks good, but I’ll buy those when PCI 5.0 comes out.

    AMD shows savings on CPU's, but they get you on the motherboards lol. Expensive, and a little less expensive X, and B series... That and the RAM some claim is needed (any cheap e-die that can oc to 3600 CL16 is all you need).

    How about A series mobo's with X chips since ocing has minimal returns. Those should be fine up to 3700x unless I'm missing something.

    I love reading these articles on AnandTech, been following AT since way back in early 2000s and it was the review of the Sandy Bridge i5 that pushed me to pick that CPU back then and subsequently used their overclocking guide to OC the CPU to the brink.

    I still have that CPU and board (ASUS P8P67 Pro) since then and am finally ready for an upgrade. This site has been an enormous pool of information on decision making. Finally moving to an AMD PC build for the first time in my life.

    Been reading several years of CPU and motherboards reviews and it's been a fascinating dive into each article as I love the details discussed in each of them.

    I seriously considered the Gigabyte Aurous Elite that was recommended but I find several manufacturers disable SATA ports when using the 2nd or 3rd m.2 slot. My use case needs all the SATA ports available to me, all ports need to be enabled for me in fact. So finally picked the MSI Tomahawk X570 which has been touted by all the tech tubers of late.

    The Asus TUF Gaming X570 Pro (2020 refresh) was another choice that ticked all my boxes but ultimately lost out on chipset fan placement.

    Just thought I'd mention my two cents in addition to the excellent board recs listed here. Can't wait for the incoming reviews and coverage of AMD's new releases.

    Keep up the amazing work!
