The next notable release to expect from AMD, after the launch of the new B550 chipset, is their upcoming Zen 2­+ 3000XT Matisse Refresh CPUs. Recently, AMD has had nearly all of its Zen 2 processors on offer for deep discounts. It’s almost as if they’re rubbing their drastic surge in performance, popularity, and price-to-performance value in the face of Intel’s new 10th Generation Comet Lake CPUs. Now, with the announced Zen 2 3600XT, 3800XT, and 3900XT, available July 7th, we’re looking at single-core boost clocks 100-200MHz higher than their predecessors for roughly a 5% performance uplift overall. While these results aren’t groundbreaking, they’re certainly enough to stick it to Intel’s new 10th Gen K-Series CPUs yet again. Furthermore, because the new XT chips are coming in at the original prices we saw with the 3600X, 3800X, and 3900X, we’ll see those discounts for current Zen 2 processors become permanent!

Today, in anticipation of AMD’s new kids on the block, we’ll be taking a look at the new Ryzen 9 3900XT and giving you our recommendations for the best motherboards to consider purchasing alongside it!

Best Entry-Level Motherboard for Ryzen 9 3900XT


The Asus TUF Gaming X570-Plus (Wi-Fi) represents some of the best price-to-performance on the market for any mid to high-end Ryzen CPU, especially for something like the 3900XT. Considering we’re this late in the game with the AM4 socket, the “cream has risen to the top,” so to speak, and you’re almost guaranteed to see many similar recommendations consistently over time. Asus’s TUF Gaming series has proven a reliable option for many different Intel and AMD chipsets for years, including X570, and that’s why it gets a nod from us again today.

With the TUF Gaming X570-Plus (Wi-Fi) you get 50A Power Stages, a 14 Phase VRM (12+2), support for up to 128GB of DDR4-4400MHz memory, 2x M.2 slots, Realtek 1G LAN + ALC S1200A Audio CODEC, 3x USB 3.2 Gen 2 (1 is Type-C) + 4x USB 3.2 Gen 1 ports, and 8x SATA III 6Gb/s ports for $190. For builders in search of the most well-rounded motherboard under $200 to pair with any Ryzen CPU, the X570-Plus (Wi-Fi) is hard to pass up.

Best Overall Motherboard for Ryzen 9 3900XT

MSI MEG X570 Unify

You may experience some déjà vu regarding our best overall pick for the 3900XT: The MSI MEG X570 Unify. Considering many early, and worrying, reports regarding many of MSI’s VRM temperatures for their X570 motherboards priced under the MEG X570 Ace, the X570 Unify is a world-class response from a motherboard manufacturer. With the X570 Unify, MSI has shown they’re genuinely determined to improve, in terms of overall product quality and their commitment to their userbase. The X570 Unify is universally praised, and rightfully so, for being arguably the best “total package,” capable of handling any component you decide to install on it.

The X570 Unify offers 60A Power Stages, a 15 Phase VRM (12+2+1), support for up to 128GB of DDR4-5000MHz memory, 3x M.2 slots, Intel AX200 Wi-Fi 6 + Bluetooth 5.0, Realtek 2.5G LAN + ALC1220 Audio CODEC, 4x USB 3.2 Gen 2 (1 is Type-C) + 2x USB 3.2 Gen 1 + 2x USB 2.0 ports, 4x SATA III 6Gb/s ports, an integrated I/O shield, Clear CMOS + BIOS Flashback buttons, onboard Power/Reset buttons, and a POST code readout for $300. If you’re not in the market for something smaller, or cheaper, the X570 Unify is an extremely sleek and powerful motherboard for your new 3900XT.

Best High-Performance Motherboard for Ryzen 9 3900XT


Given that the 3900XT will cost $500 on release, we’re going all out with our high-performance pick this time: The $700 Gigabyte X570 Aorus Xtreme. Ryzen 9 processors are monstrous, with 12 cores/24 threads on the 3900X and XT, 16 cores/32 threads on the 3950X, 105W TDPs (thermal design powers), and eye-watering performance across all multi-threaded productivity workloads, they’re some of the best consumer desktop CPU on the market, period. If you’re buying one of the best workhorse processors around, you’re likely interested in the best motherboards as well, and the X570 Aorus Xtreme is the king of VRM thermal performance, while also having the benefit of a passively cooled chipset!

The X570 Aorus Xtreme comes barreling in with 70A Power Stages, a direct 16 Phase VRM (14+2), support for up to 128GB DDR4-3600MHz memory, 3x M.2 slots (PCIe 4.0), AQUANTIA 10G LAN, Intel Gigabit LAN + AX200 Wi-Fi 6 + Bluetooth 5.0, Realtek ALC1220-VB Audio CODEC + ESS SABRE9218 DAC, 6x USB 3.2 Gen 2 (1 is Type-C) + 2x USB 3.2 Gen 1 + 4x USB 2.0 ports, 6x SATA III 6Gb/s ports, onboard Power/Reset buttons, Clear CMOS + Q-Flash buttons, and a POST code readout!

Of course, we’re well aware that a $700 price tag may have made some of you audibly laugh, and that’s entirely fair. If you’re like the majority of even PC enthusiasts, and you don’t have money positively burning a hole in your pocket, you’re going to want to check out the Asus ROG Crosshair VIII Hero (Wi-Fi). The Crosshair VIII does not have passive cooling and typically ends up running a few degrees hotter than the X570 Aorus Xtreme. Still, it’s nearly 50% cheaper at only $380 for otherwise identical features. While Asus may run “teamed” phases, they’re not cheaply/improperly “doubled” without the prerequisite additional high-quality components. Not adding the necessary hardware to a doubled VRM design is a supremely inefficient (and potentially dangerous) way manufacturers occasionally try and “raise” phase counts to match better designed VRM configurations. Asus has undoubtedly been doing things right. Where both the Gigabyte X570 Aorus Xtreme and MSI MEG X570 Godlike cost $700, the Asus Crosshair VIII Hero (Wi-Fi) readily competes in terms of clean power delivery and thermal performance at a massively lower price point. If you’re not sweating (😊) the few extra degrees and still desire one of the best enthusiast AMD motherboards out there, the Crosshair VIII Hero (Wi-Fi) significantly lessens the impact on your wallet for the same quality and features across the board.

Best mATX Motherboard for Ryzen 9 3900XT

Asus TUF Gaming B550M-Plus WiFi

Ahh, mATX, the criminally underappreciated form factor ☹. Despite being every bit as capable of providing top-tier VRM configurations, hardware compatibility, connectivity options, and overall design quality, builders and motherboard manufacturers alike seem to be a bit disinterested mATX. This disinterest, in addition to the massive spike in popularity of small form factor (SFF) mini-ITX builds, leads to regularly sparse micro motherboard options for both AMD and Intel chipsets. Thankfully, we have the $180 Asus TUF Gaming B550M-Plus (Wi-Fi) to make up for the general lack of higher-end mATX motherboards we’ve seen, especially with B450 and X570.

The TUF Gaming B550M-Plus (Wi-Fi) provides 50A Power Stages, a 10 Phase VRM (8+2), support for up to 128GB DDR4-4600MHz memory, 2x M.2 slots (1x PCIe 4.0 x4), Intel AX200 Wi-Fi 6 + Bluetooth 5.1, Realtek 2.5G LAN + ALC S1200A Audio CODEC, 2x USB 3.2 Gen 2 (1 is Type-C) + 4x USB 3.2 Gen 1 + 2x USB 2.0 ports, 4x SATA III 6Gb/s ports, and BIOS Flashback. If you find yourself interested in building an mATX Ryzen system, the TUF Gaming B550M-Plus (Wi-Fi) is your best bet, especially when it comes to VRM performance and rear I/O USB connectivity.

Best mini-ITX Motherboard for Ryzen 9 3900XT

ASUS ROG Strix X570-I Gaming

Considering the aforementioned interest in mini-ITX builds as of late, the Asus ROG STRIX X570-I Gaming is enough to say that their prevalence will only continue to rise. At $250, there’s a good reason for the X570-I Gaming’s consistent appearance as our recommendation for the best Ryzen mini-ITX board; it’s beastly. Of course, there are other excellent contenders for mini-ITX Ryzen motherboards (especially on B550), but if you’re choosing a Ryzen 9 CPU for your next SFFPC, you’re going to want the best, and the ROG STRIX X570-I delivers.

This tiny Asus board touts 70A Power Stages, a 10 Phase VRM (8+2) with active cooling, support for up to 64GB of DDR4-4800MHz memory, 2x M.2 slots, Intel Gigabit LAN + AX200 Wi-Fi 6 + Bluetooth 5.0, SupremeFX S1220A Audio CODEC, 4x USB 3.2 Gen 2 (1 is Type-C) + 4x USB 3.2 Gen 1 ports, and 4x SATA III 6Gb/s ports. Thanks to the active VRM cooling for already robust power delivery, the X570-I Gaming is guaranteed to keep even a 3950X nice and cool in all but the most restrictive SFF cases!


Even if you don’t want to opt for marginally worse price-to-performance by picking up a new Zen 2 CPU, the Matisse Refresh is excellent news for anybody looking to build a new AMD PC. It’s also important to reiterate that the discounted pricing for Zen 2 Ryzen 3000 processors might become permanent. Thus, in addition to the improved performance available to those with a bit more cash for Zen 2, AMD continues to prove themselves a killer option for any builder that’s interested in high-performance computing. The fact that there are so many fabulous AMD motherboard options to choose from is just icing on the cake!

Best Entry-Level: Asus TUF Gaming X570-Plus (Wi-Fi) – The tried and true TUF Gaming series from Asus continues to deliver stellar price-to-performance value, under $200, for even the top-tier Ryzen CPUs.

Best Overall: MSI MEG X570 Unify – MSI knocked it out of the park with the X570 Unify, and at the same time, proved they’re committed to their users and the overall quality of their products. If you’re in the price range for it, the X570 Unify is arguably the sleekest and most compelling X570 motherboard to date.

Best High-Performance: Gigabyte X570 Aorus Xtreme – Raw, undeniable performance… For a price. At $700, Gigabyte is asking a lot, but the Aorus Xtreme truly offers best-in-class VRM performance, extensive connectivity, and build quality. However, if you nearly choked at the thought of spending $700 on a motherboard, the Asus ROG Crosshair VIII Hero (Wi-Fi), is the best reasonable enthusiast-class X570 at nearly half the price; $380.

Best mATX: Asus TUF Gaming B550M-Plus (Wi-Fi) – Asus provides one of the absolute best mATX AM4 motherboards to date, with equivalent VRM performance compared to its direct competition, but with superior rear I/O USB connectivity.

Best mini-ITX: Asus ROG STRIX X570-I Gaming – Despite a strong lineup of high-end mini-ITX AM4 motherboards for X570 and B550, the X570-I Gaming still comes out on top. Especially for a high-end Ryzen 9 3900XT or 3950X, Asus is the king of the SFF scene.
