AMD Ryzen 9 3950x is perhaps the best desktop processor today. Boasting 16 true multithreading cores, this CPU is a productivity monster. Its 16core/32 design makes it great at both single-threaded and multithreaded tasks.
With a higher boost speed (4.7GHz) than any of its predecessors, this processor is way better than the 3900x. It runs 10 degrees cooler than the 3900x and draws 4 watts less than 3900x. If you are not overclocking, you don’t need to go all out with enthusiast cooling.
Today, we are not going head to head with the 3900x but rather finding out the best motherboard to go with your new Ryzen 9 3950x.
When it comes to exceptional performance, motherboards are quite distinct. Older X470 motherboards may leave you asking for more.
So, for Ryzen 9 3950x, we are only going to recommend X570 motherboards. From the VRM quality to expandability, you will want a motherboard that can power 16 cores sufficiently.
Consider the following factors before buying Ryzen 9 3950x motherboard
You’ll need clean power for 16 cores. The motherboard should cover extended periods of overclocking.
The chipset should be compatible with the 3950x. To ensure that all the hardware communicates effectively with each other, we recommend the X570 chipset.
This way, you won’t have to modify your BIOS. The 3950x has the new 220.127.116.11B AGESA code. It is a remarkable improvement in AMD’s auto overclocking PBO (Precision Boost Overdrive).
Hence, you can count on crazy fast speed when you want it.
PCIe slots, M.2 slots, RAM slots, and SATA ports are essential for storage. Especially for gaming, you don’t want to run out of either memory or storage.
Requirements for an X570 Motherboard for the 3950x
All AMD mainstream CPUs including the 3950x, use the AM4 socket. However, a B350 board will not support the 3950x processor or any of the 3000 series chips. You will need a motherboard that offers PCIe 4.0 support.
Unless you are building a super workstation PC with AMD’s Threadripper CPU-series that work with the TR4X socket, we suggest sticking with the AM4 socket.
An ATX or ITX Form Factor
Fortunately, the 3950x processor is so small that it can fit on an ITX motherboard without affecting its performance. If space is tight, you should consider an ITX motherboard. But if the scale of your build is not dependent on space, the ATX form factor is a sweet spot for most needs.

FAQs for the Best Motherboard for Ryzen 9 3950x
1. Do x570 need BIOS update for Ryzen 3000 CPUs?
All x570 boards are guaranteed to work on all 3rd generation Ryzen CPUs out of the box. It’s worth considering if you want 100% compatibility without worrying about the BIOS. AMD has assured that even Zen-3 based processors set to be unveiled later in the year will support X570 motherboards. So, no worries there either.
2. Do you need additional cooling for M.2 SSD?
Most motherboards require that you install the M.2 SSD right where they are exposed to board cooling. And because SSDs are made to withstand extreme temperatures, additional onboard cooling is not necessary.
3. Will an X470 motherboard hold Ryzen 9 3950x
If you already have an X470 motherboard and don’t need PCIe 4.0 you are good to install the 3950x. But if you are buying a new motherboard, we recommend going with the X570. This is because good X470 motherboards tend to be more expensive than some X570 motherboards.
4. Why do X570 motherboards need active cooling?
Nearly all X570 boards come with a chipset fan. Eric Van Beurden of MSI says that it’s much needed on the X570 platform. This is because the chipset requires lots of power to run the PCIe 4.0 socket. It’s even speculated that the TDP for X570 is at15W. That’s why there’s the need for active cooling.
5. Can you make X570 passive or semi-passive cooled?
If you are a DIY enthusiast, it’s possible to achieve passive cooling on the X570. But it involves a lot of work, and ultimately you have to get air blowing over the heatsink leading from the graphics card.
Or, you could get the Gigabyte X570 AUROS Extreme. But it comes at a steep price tag, which is not worth it just to go without fans.
The new Ryzen 9 3950x processor is best-paired with the X570 chipset. And although the chipset is new, there are numerous X570 motherboards on the market already. Which is why you should not make a choice lightly.
If you are on a budget, we recommend the Asus Prime X570-Pro. But if you are all in with premium features, ASUS ROG Crosshair VIII Hero X570 is our top choice for gaming.
