ASRock B850M-X VS Gigabyte B840M Eagle WiFi6

Both boards share a strong common foundation: the AM5 socket and Micro-ATX form factor make them direct competitors targeting the same class of compact AMD builds. They match on HDMI 2.1 output, overclocking support, dual BIOS protection, and a 3-year warranty — so neither board has a structural advantage in platform compatibility or long-term reliability on paper.

The clearest differentiator in this group is connectivity. The Gigabyte B840M Eagle WiFi6 includes both Wi-Fi and Bluetooth, while the ASRock B850M-X omits both entirely. In practice, this matters most in builds where routing a wired Ethernet cable is inconvenient, or where Bluetooth peripherals — headsets, controllers, or wireless keyboards — are part of the setup. Users going with the ASRock will need to budget for a separate PCIe or USB wireless adapter to match that capability, which adds cost and consumes an expansion slot or port.

The Gigabyte is also marginally taller at 244 mm versus the ASRock's 226 mm, though both share an identical 244 mm width. This height difference is minor but worth checking against shorter Micro-ATX cases with tight vertical clearance. Overall, the Gigabyte B840M Eagle WiFi6 holds a clear edge in this group purely due to its built-in wireless capabilities — a meaningful convenience advantage for most modern desktop users.

The ASRock B850M-X and Gigabyte B840M Eagle WiFi6 are both equipped with similar memory features, such as supporting up to 128GB of maximum memory. Both motherboards have 2 memory slots, DDR5 memory version, and 2 memory channels. Additionally, neither supports ECC memory.

However, the boards differ in terms of overclocked RAM speed. The ASRock B850M-X supports a higher overclocked RAM speed of 8200 MHz, while the Gigabyte B840M Eagle WiFi6 supports a slightly lower overclocked RAM speed of 7200 MHz.

Overall, the two motherboards have very similar memory specs, with the key difference being the higher supported overclocked RAM speed on the ASRock B850M-X.

The ASRock B850M-X and Gigabyte B840M Eagle WiFi6 offer a range of ports, but there are some notable differences between them. Both motherboards feature HDMI output and DisplayPort outputs, along with a single RJ45 port for Ethernet connectivity. The ASRock B850M-X provides a total of 3 USB 3.2 Gen 1 Type-A ports, 1 USB 3.2 Gen 1 Type-C port, and 2 USB 2.0 ports, as well as a USB Type-C port. The Gigabyte B840M Eagle WiFi6, on the other hand, offers 2 USB 3.2 Gen 1 Type-A ports, but lacks a USB 3.2 Gen 1 Type-C port, and has 4 USB 2.0 ports.

When it comes to more specialized ports, both boards lack USB 3.2 Gen 2x2, USB 4 40Gbps, or Thunderbolt ports. The ASRock B850M-X has no PS/2 ports, whereas the Gigabyte B840M Eagle WiFi6 includes a PS/2 port for legacy peripherals. Additionally, the ASRock board supports USB Type-C, while the Gigabyte board does not.

In summary, both motherboards have similar port offerings, but the ASRock B850M-X includes more modern USB Type-C support and fewer USB 2.0 ports compared to the Gigabyte B840M Eagle WiFi6, which compensates with a PS/2 port.

The ASRock B850M-X and Gigabyte B840M Eagle WiFi6 have similar connector offerings, with both providing 2 USB 3.2 Gen 1 ports through expansion and 4 USB 2.0 ports through expansion. Both motherboards also offer 4 SATA 3 connectors and 2 M.2 sockets, allowing for flexible storage options. In terms of fan headers, the ASRock B850M-X has 6, while the Gigabyte B840M Eagle WiFi6 has 4, giving the ASRock model a slight advantage for additional cooling options.

Both motherboards are equipped with a TPM connector and lack an mSATA connector. Neither board has U.2 sockets or SATA 2 connectors, so these features are not available on either model.

In summary, the main difference between the two products in this group is the number of fan headers, with the ASRock B850M-X offering more. Otherwise, both motherboards have very similar connectivity options, including USB and storage connectors.

The ASRock B850M-X and Gigabyte B840M Eagle WiFi6 differ in their expansion slot configurations. The ASRock B850M-X provides 2 PCIe 4.0 x16 slots, while the Gigabyte B840M Eagle WiFi6 offers only 1 PCIe 4.0 x16 slot. In addition, the ASRock board includes 1 PCIe x1 slot, which is not present on the Gigabyte model.

On the other hand, the Gigabyte B840M Eagle WiFi6 has 1 PCIe x4 slot, which the ASRock B850M-X does not have. Neither motherboard offers any PCIe 5.0, PCIe 3.0, or PCI slots, and both lack PCIe 2.0 x16 and PCIe x8 slots.

In summary, the ASRock B850M-X offers more PCIe x16 slots, while the Gigabyte B840M Eagle WiFi6 provides a PCIe x4 slot, which the ASRock model lacks. Both motherboards have distinct slot configurations to suit different expansion needs.

Both the ASRock B850M-X and Gigabyte B840M Eagle WiFi6 offer 7.1 audio channels, providing a similar high-quality audio experience. Neither motherboard features an S/PDIF Out port, which may be important for users seeking digital audio output. Both models are equipped with 3 audio connectors, ensuring basic connectivity for audio devices such as speakers or headphones.

In summary, the audio specifications are identical across both products, with no significant differences between the ASRock B850M-X and Gigabyte B840M Eagle WiFi6 in terms of audio channels, S/PDIF support, or the number of audio connectors.

The ASRock B850M-X and Gigabyte B840M Eagle WiFi6 both support RAID 1 and RAID 10 (1+0), allowing for mirrored and striped configurations. However, they differ when it comes to RAID 5 support. The ASRock B850M-X does not support RAID 5, while the Gigabyte B840M Eagle WiFi6 does. Both motherboards also support RAID 0, but neither supports RAID 0+1.

In summary, the key difference between the two boards in terms of storage is that the Gigabyte B840M Eagle WiFi6 offers RAID 5 support, which the ASRock B850M-X lacks. Both boards share the same RAID 1, RAID 10 (1+0), and RAID 0 support, with no support for RAID 0+1.
