This motherboard has everything you need to build a capable AMD-powered PC, including Ryzen 3000 series support, X570 chipset, PCIe 4.0 support, Wi-Fi, Bluetooth 5.0, cooling for the voltage regulator modules, and more. In fact, you could even push this motherboard a little further with some overclocking.

This compact motherboard supports AMD Ryzen 3000 series processors and is a compact platform for smaller PC builders. An ITX motherboard can fit inside smaller PC cases, allowing you to build more unique desktops. It’s no slouch, though. You’ve got two DIMM RAM slots, an 8-phase digital voltage regulation module solution, Wi-Fi, dual M.2 slots, and PCIe 4.0 support.

ASUS has the ROG Crosshair VIII Hero X570 that’s an absolute monster of a motherboard. Not only does it rock the high-end AMD chipset, but also some other highlight features. You’ve got one excellent VRM setup that allows for some serious overclocking, PCIe 4.0 support, all the USB 3.2 ports and M.2 slots you need, and even 2.5Gb LAN. It’s for high-end, capable PC builds.

What makes PCIe 4.0 so special?

PCIe stands for peripheral component interconnect express. It’s a standard that allows your PC to communicate with various expansion cards, be it your GPU, sound card, wi-fi or ethernet adapters, and even M.2 SSD storage. Coming in at x1, x4, x8, or x16 lanes, the higher the number essentially means the more bandwidth available.

Depending on what you need to install onto the motherboard, you’ll need to match up the PCIe lane numbers. For graphics cards, you need to use x16. A Wi-Fi or ethernet hub may only require x1 or x4. The more lanes, the larger the slot is on the motherboard. Most modern motherboards come with a mixture of slots. The largest ones (usually between one and three) are x16.

Like the number of lanes available, PCIe 4.0, compared to PCIe 3.0, is basically more bandwidth. The good news is everything is backward compatible, so you could use a PCie 4.0 GPU on a PCIe 3.0 motherboard, or vice-versa though you won’t get all the benefits from a PCIe 4.0 component.

NVIDIA’s latest GPUs are PCIe 4.0 certified and, as such, will run a little better on motherboards that also support the standard. These motherboards will be a good fit for a modern gaming PC build.

Choosing the best AMD AM4 motherboard with PCIe 4.0

Choosing the best motherboard for your build primarily comes down to what you need. If you’re only after PCIe 4.0 support and don’t mind about any other feature, the ASUS AM4 TUF Gaming X570-Plus (Wi-Fi) is an excellent choice that doesn’t cost too much either.

If you want to build a more compact system, something like the GIGABYTE X570 I AORUS Pro Wi-Fi would be a better match, being able to be installed inside smaller mini-ITX cases. It only comes with a single x16 PCIe 4.0 slot, but does allow you to throw on your favorite GPU.
