AM5 covers Ryzen 7000, 8000 and 9000 chips on four main chipsets. The chipset changes the number of fast lanes and USB ports, not gaming speed.

We picked six boards across X870E, X870, B850 and B650. This is a research-based comparison built from maker specifications and retailer listings; we did not test these parts ourselves.

Our Picks

Best Value B8501 of 6

MSI MAG B850 Tomahawk MAX WiFi

The B850 Tomahawk MAX covers what most Ryzen builds need: four M.2 slots, 5Gbps Ethernet and Wi-Fi 7.

Best for

Most Ryzen gaming builds.

Skip if

If budget leads, the B650M PG Lightning was cheaper at our last price check.
MSI MAG B850 Tomahawk MAX WiFi

Why we like it

It matches the TUF X870E-PLUS on M.2 slot count (4). It matches the X870 Tomahawk on wired network speed (5Gbps). It also comes with a PCIe 5.0 x16 slot with Steel Armor and a rear USB 20Gbps Type-C port.

It uses AMD's AM5 socket, so it takes Ryzen 7000, 8000 and 9000 chips; a board built before a CPU's launch may need a BIOS update first, so check whether it supports BIOS Flashback. Check the manual for which M.2 slots share lanes with SATA ports or the second PCIe slot before filling them all. When we checked, only the B650 Tomahawk and cheaper picks cost less, and the X870 Tomahawk cost more.

Best X870E Pick2 of 6

ASUS TUF Gaming X870E-PLUS WiFi 7

The TUF X870E-PLUS offers four M.2 slots and a 16+2+1 layout of 80A power stages on the X870E chipset.

Best for

Ryzen 9 builds that want the top chipset.

Skip if

Its wired network speed is not published, which rules it out if you need that number.
ASUS TUF Gaming X870E-PLUS WiFi 7

Why we like it

On M.2 slot count it ties with the B850 Tomahawk MAX at 4. You also get a PCIe 5.0 graphics slot. It uses AMD's AM5 socket, so it takes Ryzen 7000, 8000 and 9000 chips; a board built before a CPU's launch may need a BIOS update first, so check whether it supports BIOS Flashback.

Check the manual for which M.2 slots share lanes with SATA ports or the second PCIe slot before filling them all. It was the highest-priced of the 6 picks at the time of writing, so the case for it rests on what it adds over the X870 Tomahawk and the rest.

The catch

The maker doesn't give its wired network speed; if that figure matters, the B850 Tomahawk MAX offers 5Gbps.

Solid Alternative3 of 6

MSI MAG X870 Tomahawk WiFi

The X870 Tomahawk pairs 5Gbps Ethernet with Wi-Fi 7 and USB4, covering the connectivity most builders want for years.

Best for

Buyers who want 5gbps wired ethernet.

Skip if

Skip it if you need to know its M.2 slot count before buying; the maker doesn't publish one.
MSI MAG X870 Tomahawk WiFi

Why we like it

It has 5G LAN, an extended VRM heatsink and isolated Audio Boost 5. It matches the B850 Tomahawk MAX on wired network speed (5Gbps). An X870 chipset is unique to it among these picks, while the B650 Tomahawk uses a B650 chipset.

It also offers a PCIe 5.0 M.2 slot and Bluetooth 5.4 alongside Wi-Fi 7. It uses AMD's AM5 socket, so it takes Ryzen 7000, 8000 and 9000 chips; a board built before a CPU's launch may need a BIOS update first, so check whether it supports BIOS Flashback. When we checked, only the B850 Tomahawk MAX and cheaper picks cost less, and the TUF X870E-PLUS cost more. If you want a confirmed M.2 slot count, look to the B850 Tomahawk MAX instead: it offers 4, while this one gives no figure.

Worth Considering4 of 6

MSI MAG B650 Tomahawk WiFi

The B650 Tomahawk is the steady middle of the B650 range: Wi-Fi 6E, 2.5Gbps Ethernet and display outputs on an ATX board.

Best for

Buyers who want lightning m.2 support.

Skip if

Skip it if this is a deal-breaker for you: wi-Fi 6E rather than Wi-Fi 7.
MSI MAG B650 Tomahawk WiFi

Why we like it

It has no PCIe 5.0 graphics slot, which matters little for today's cards. It matches the B850M Steel Legend and the B650M PG Lightning on wired network speed (2.5Gbps). Like the B650M PG Lightning, it has a wi-Fi 6E, while the B850 Tomahawk MAX uses a wi-Fi 7.

It also comes with Lightning M.2 support, Bluetooth 5.3 alongside Wi-Fi 6E and HDMI and DisplayPort outputs for Ryzen chips with graphics. It uses AMD's AM5 socket, so it takes Ryzen 7000, 8000 and 9000 chips; a board built before a CPU's launch may need a BIOS update first, so check whether it supports BIOS Flashback. When we checked, only the B850M Steel Legend and cheaper picks cost less, and the B850 Tomahawk MAX cost more.

Best Micro-ATX5 of 6

ASRock B850M Steel Legend WiFi

The B850M Steel Legend fits a 12+2+1 layout, Wi-Fi 7 and three M.2 slots, one of them PCIe 5.0, onto a Micro-ATX board.

Best for

Compact Ryzen builds.

Skip if

Skip it if M.2 slot count matters most to you; the B850 Tomahawk MAX offers 4.
ASRock B850M Steel Legend WiFi

Why we like it

It is the Micro-ATX pick with the most features here. On M.2 slot count it trails the group at 3, while the B850 Tomahawk MAX offers 4. On wired network speed it ties with the B650 Tomahawk and the B650M PG Lightning at 2.5Gbps.

You get 12+2+1 power stages here, which sets it apart from the B650M PG Lightning and its 6+2+1 power stages. No other pick in this guide offers a B850 chipset; compare the X870 Tomahawk, which has an X870 chipset. It also offers BIOS Flashback and a white and silver finish.

It uses AMD's AM5 socket, so it takes Ryzen 7000, 8000 and 9000 chips; a board built before a CPU's launch may need a BIOS update first, so check whether it supports BIOS Flashback. On price it sat second of 6, between the cheaper B650M PG Lightning and the pricier B650 Tomahawk, at the time of writing.

Lowest Price6 of 6

ASRock B650M PG Lightning WiFi

The B650M PG Lightning is the cheapest route onto AM5 here, a Micro-ATX board with Wi-Fi 6E, 2.5Gbps LAN and BIOS Flashback.

Best for

Budget Ryzen 5 builds.

Skip if

Skip it if this is a deal-breaker for you: wi-Fi 6E rather than Wi-Fi 7.
ASRock B650M PG Lightning WiFi

Why we like it

Its 6+2+1 layout is best kept to six- and eight-core chips. It matches the B650 Tomahawk and the B850M Steel Legend on wired network speed (2.5Gbps). Like the B650 Tomahawk, it has a wi-Fi 6E, while the X870 Tomahawk uses a wi-Fi 7.

No other pick in this guide offers 6+2+1 power stages; compare the TUF X870E-PLUS, which has 16+2+1 power stages. It also offers memory support up to DDR5-7200 (OC) and the lowest price among the AM5 boards here. It uses AMD's AM5 socket, so it takes Ryzen 7000, 8000 and 9000 chips; a board built before a CPU's launch may need a BIOS update first, so check whether it supports BIOS Flashback. It cost the least of the 6 picks at the time of writing, with the B850M Steel Legend the next step up.

How We Chose These AM5 Motherboards

Alex Morgan compared the manufacturer specifications, connectivity, warranty terms and compatibility of every pick. Figures come from the makers unless a third-party source is named; we did not test these products ourselves.

The figures behind the order
We compared six boards on M.2 slot count, wired network speed, wi-Fi and power stages as the makers state them. Nothing was tested in-house; 3 of the 7 fields compared are stated for every pick, while M.2 slot count and wired network speed have gaps.
The shared baseline
All 6, from the B850 Tomahawk MAX to the B650M PG Lightning, state wi-Fi, form factor and socket and share AM5 socket.
Where the specs have gaps
The X870 Tomahawk, the B650 Tomahawk and the B650M PG Lightning give no M.2 slot count; the TUF X870E-PLUS gives no wired network speed.
Price range
At our last check the picks ran from the B650M PG Lightning ($100 to $150) to the TUF X870E-PLUS ($150 to $250).

What to Look for in an AM5 Motherboard

Key buying criteria so you get the right fit the first time.
