The Best Motherboards for Ryzen 9 9950X3D
From the PRO B850-P to the X870E AORUS Master: five motherboards ranked on M.2 slot count and wired network speed, with who should skip each one.
By The PC Journal editorial team
12 min read5 products evaluated
The Ryzen 9 9950X3D is a 16-core chip, and a board with 5G LAN and Wi-Fi 7 keeps the rest of the platform at its level. Every pick is an AM5 board with 5G LAN and Wi-Fi 7, ordered by M.2 slot count.
Our comparison rests on published figures for M.2 slots, wired LAN and wi-Fi; nothing here was tested in-house, and where a maker leaves out power stages, we say so.

MSI MAG B850 Tomahawk MAX WiFi on Amazon (opens in a new tab)
The B850 Tomahawk MAX covers what most Ryzen builds need: four M.2 slots, 5Gbps Ethernet and Wi-Fi 7 on a reinforced PCIe 5.0 graphics slot.
Best for
- Buyers who want PCIe 5.0 x16 slot with Steel Armor.
Skip if
- Price-first buyers should look at the PRO B850-P, which cost less when we checked.
Why we like it
It is the board to start from unless you need something specific. It matches the Strix B850-F NEO, the X870E Tomahawk MAX PZ and the X870E AORUS Master on M.2 slot count (4). 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 PRO B850-P cost less, and the Strix B850-F NEO cost more.

How We Chose These Motherboards for Ryzen 9 9950X3D
Each pick was assessed across 4 criteria weighted for real-world use.
- How these picks were ranked
- We set side by side five boards on M.2 slot count, wired network speed, wi-Fi and power stages from manufacturer specifications. We did not test them in-house, and power stages and USB4 are missing for at least one pick.
- The shared baseline
- All 5, from the B850 Tomahawk MAX to the PRO B850-P, state M.2 slot count, wired network speed and wi-Fi and share Wi-Fi 7 wi-Fi and AM5 socket.
- Where the specs have gaps
- The B850 Tomahawk MAX, the X870E Tomahawk MAX PZ and the PRO B850-P give no power stages; the B850 Tomahawk MAX, the Strix B850-F NEO and the PRO B850-P give no USB4.
- Price range
- At our last check the picks ran from the PRO B850-P ($100 to $150) to the X870E AORUS Master ($250 to $500).
