Motherboard Requirements for Ryzen 9 9900X3D Processors

Section Link

For AMD's Zen 5-based Ryzen 9 9900X3D processor, you'll need a motherboard with an AM5 socket and a compatible chipset.

Motherboards for AMD processors are made with chipsets provided by AMD. Each chipset offers a unique set of capabilities. However, motherboards must explicitly support features and capabilities for you to use them. Verify that a motherboard supports the features and capabilities you desire.

Ryzen 9000-series CPUs, which includes the Ryzen 9 9900X3D, are compatible with the 600-series consumer chipsets. Supported chipsets include the X670E, X670, B650E, and B650.

The X670E is our recommended motherboard chipset for the Ryzen 9 9900X3D CPU, as it provides the most functionality and full support for PCIe 5.0. The Ryzen 9 9900X3D CPU also supports PCIe 5.0.

Other Considerations When Choosing a 9900X3D Motherboard

Section Link

When choosing a motherboard for the 9900X3D, we've thought of a few other factors you may want to consider. This is in addition to selecting a compatible socket type and chipset. As we delved into our research and analyzed various options, we identified several considerations that played a significant role in determining the ideal chipset for our needs. Our considerations can help you narrow down which features are important to look for.

Video Output Port

The lack of a "G" in the 9900X3D model name indicates that the CPU does not have integrated graphics support and requires a separate graphics card. Because it doesn't have integrated graphics support, you won't need a motherboard with a video output port (e.g., HDMI).

Storage: M.2 Slots and SATA Ports

NVMe M.2 cards are the latest and fastest form of SSD storage. However, we suggest ensuring your motherboard includes enough slots.

NVMe Support: The X670E, X670, and B650E chipsets support up to one x4 NVMe at PCIe 5.0 speeds (via CPU) and up to one x4 NVMe at PCIe 5.0 speeds (via chipset). The B650 chipset supports one x4 NVMe at PCIe 4.0 speeds (via CPU).

SATA Support: The X670E and X670 chipsets support up to 8 SATA ports, while the B650E and B650 chipsets support up to 4 SATA ports.

Connectivity

USB

We found that it's wise to make sure the motherboard provides enough USB ports at your desired speeds.

The X670E and X670 chipsets support up to 12 superspeed (10Gbps) USB ports and 2 superspeed (20Gbps) USB ports. The B650E and B650 chipsets, in comparison, only support up to 6 superspeed (10Gbps) USB ports and 1 superspeed (20Gbps) USB port. Each motherboard is different, so the amount and speed of USB ports may vary.

In our experience, the devices that usually require high bandwidth rates are primarily limited to storage devices and high-resolution video devices. We have observed that these devices often rely heavily on fast data transfer speeds. In fact, we encountered situations where slower bandwidth rates significantly hindered such devices' performance.

We've tested various storage devices and found that the ones capable of handling large amounts of data transfer at high speeds yielded the best results. Similarly, when working with high-resolution video devices, we discovered that a reliable and fast connection was crucial for seamless playback and editing. Through our experience, we have come to appreciate the significance of high bandwidth rates for these specific types of devices.

Audio

We recommend making sure the motherboard has audio outputs. In my experience, it's crucial to check for rear and center speaker ports if you're using a surround sound system.

If you're like me and your audio equipment relies on optical input, it's worth looking for a motherboard that includes this specific port. On the other hand, we've found that you can also buy a separate PCIe or USB sound card. This way, you can expand your port options and even add features like optical or RCA connections based on your own preferences.

Form Factor

When it comes to motherboards, we've encountered three primary form factors. In our experience, ATX stands out as the most common for desktop PCs. We've also explored Mini-ITX and MicroATX for building mini-PCs, and found they typically offer fewer PCIe slots, RAM slots, and storage support.

We've observed that these smaller form factors are backward compatible with standard ATX cases, using a subset of their mounting holes. In fact, we've frequently used Mini-ITX motherboards in ATX cases.

One crucial consideration is ensuring your case matches your motherboard's form factor. We've learned from experience how important it is to choose a case that aligns with your motherboard's specific needs.

PCIe Expansion Slots

Based on our analysis, the X670E and B650E chipsets allow for multiple graphics cards in the dual x8 configuration at PCIe 5.0 speeds, while the X670 and B650 only run at PCIe 4.0 speeds for both a single x16 slot or dual x8 slots.
