Asus TUF Gaming B850-Plus WiFi VS Gigabyte B850M Gaming X WiFi6E

Both boards share the same AM5 socket and B850 chipset foundation, meaning they target the same CPU ecosystem and offer equivalent overclocking headroom. They also match on several quality-of-life features: dual BIOS for recovery protection, RGB lighting, and a 3-year warranty. For the everyday builder, these shared traits mean neither board has a structural platform advantage over the other.

The most meaningful differentiators sit in form factor and wireless connectivity. The Asus TUF Gaming B850-Plus WiFi is a full ATX board (305 × 244 mm), while the Gigabyte B850M Gaming X WiFi6E uses a Micro-ATX footprint (244 × 244 mm). That size difference matters at build time: ATX opens up more PCIe slot spacing and generally more room for power delivery components, while Micro-ATX is the better fit for compact or mid-tower cases where space is tight. On wireless, the Asus reaches Wi-Fi 7 (802.11be), the newest standard offering significantly higher throughput and lower latency on compatible routers, whereas the Gigabyte tops out at Wi-Fi 6E. Bluetooth follows the same pattern: 5.4 on the Asus versus 5.3 on the Gigabyte, a modest but real improvement in connection stability and energy efficiency.

The Asus TUF Gaming B850-Plus WiFi holds a clear edge in this group. Its Wi-Fi 7 support is the standout advantage — it is genuinely future-proof for users investing in a next-generation router — and its slightly newer Bluetooth further extends that lead. The Gigabyte is the right pick only if a smaller form factor is a hard requirement; otherwise, the Asus delivers more for builders who want to maximize their wireless capabilities without compromising on platform features.

The Asus TUF Gaming B850-Plus WiFi and Gigabyte B850M Gaming X WiFi6E both support DDR5 memory, offering a modern memory standard for fast performance. The Asus board supports a maximum memory amount of 192GB, while the Gigabyte board can handle up to 256GB, providing more headroom for future upgrades or demanding tasks.

Both motherboards offer 4 memory slots and dual-channel memory configurations, allowing for efficient memory bandwidth. When it comes to RAM speeds, the Asus board supports a maximum RAM speed of 4000 MHz, and it can overclock to 8000 MHz. In comparison, the Gigabyte board supports a higher maximum RAM speed of 5200 MHz, with an overclocked speed of 8200 MHz, providing more flexibility in memory performance.

Neither motherboard supports ECC memory, which means they are not designed for error-correcting code memory, typically used in server or workstation applications where data integrity is critical. Overall, while both boards offer strong memory configurations, the Gigabyte B850M Gaming X WiFi6E supports a larger memory capacity and slightly higher memory speeds than the Asus TUF Gaming B850-Plus WiFi.

The Asus TUF Gaming B850-Plus WiFi and Gigabyte B850M Gaming X WiFi6E motherboards both offer a variety of USB ports, but with some differences in the number and types available. The Asus board includes 3 USB 3.2 Gen 2 (USB-A) ports, 4 USB 3.2 Gen 1 (USB-A) ports, and 2 USB 2.0 ports. In contrast, the Gigabyte board has 1 USB 3.2 Gen 2 (USB-A) port, 2 USB 3.2 Gen 1 (USB-A) ports, and 4 USB 2.0 ports. Both motherboards feature 1 USB 3.2 Gen 2 port (USB-C), but only the Asus model supports USB 3.2 Gen 2x2, with 1 port of this type, while the Gigabyte model lacks this feature.

Both motherboards come with HDMI outputs, although the Asus model also has 1 DisplayPort output, while the Gigabyte model offers 2 DisplayPort outputs, giving it an advantage in the number of display connections. Both have 1 RJ45 port for Ethernet connectivity. Neither motherboard offers USB 4, Thunderbolt ports, eSATA, or DVI outputs. The Asus TUF Gaming B850-Plus WiFi has no USB Type-C ports beyond its single Gen 2 port, while the Gigabyte board includes 1 USB Type-C port.

Neither motherboard includes VGA connectors or PS/2 ports, and both have no Thunderbolt 3 or 4 support. Overall, the Asus board stands out for its additional USB 3.2 Gen 2x2 support and DisplayPort output, while the Gigabyte board offers slightly fewer USB 3.2 Gen 2 (USB-A) ports but features an additional DisplayPort output.

The Asus TUF Gaming B850-Plus WiFi and Gigabyte B850M Gaming X WiFi6E motherboards share many similarities in their connector offerings, but there are a few key differences. Both boards provide 2 USB 3.2 Gen 1 ports (through expansion), 1 USB-C 3.2 Gen 2 port (through expansion), and 4 USB 2.0 ports (through expansion), so connectivity in these areas is identical between the two. They also both offer 4 SATA 3 connectors for storage drives and 2 USB 3.0 ports (through expansion).

One difference comes in the number of fan headers, with the Asus board providing 6 fan headers, while the Gigabyte board has 4. This means the Asus board offers more flexibility for users who require additional cooling solutions. In terms of M.2 sockets, the Asus board provides 3, while the Gigabyte board offers 2 M.2 sockets, giving the Asus board a slight advantage for users needing more M.2 storage options.

Another notable difference is that the Gigabyte motherboard includes a TPM connector, which is absent on the Asus board. Neither board has a U.2 socket, and both lack mSATA connectors, as well as SATA 2 connectors. Overall, while both motherboards have similar expansion options, the Asus model stands out with more fan headers and M.2 sockets, while the Gigabyte model includes the TPM connector.

The Asus TUF Gaming B850-Plus WiFi and Gigabyte B850M Gaming X WiFi6E offer different configurations when it comes to expansion slots. The Asus board features 1 PCIe 4.0 x16 slot and 1 PCIe 5.0 x16 slot, while the Gigabyte board offers a single PCIe 5.0 x16 slot but lacks a PCIe 4.0 x16 slot. The Asus model also includes 2 PCIe x1 slots, which the Gigabyte board does not have. On the other hand, the Gigabyte board provides a PCIe x4 slot, which is absent on the Asus model.

Neither motherboard includes PCI slots, PCIe 2.0 x16 slots, or PCIe x8 slots, so both boards have similar limitations in those areas. However, the Asus board offers greater flexibility with two PCIe x1 slots and a PCIe 4.0 x16 slot, while the Gigabyte board compensates with a PCIe x4 slot, useful for certain expansion cards.

In summary, the Asus TUF Gaming B850-Plus WiFi has more expansion slot variety with additional PCIe x1 slots and PCIe 4.0 x16 support, whereas the Gigabyte B850M Gaming X WiFi6E is focused on PCIe 5.0 with a PCIe x4 slot but fewer PCIe x1 options.

Both the Asus TUF Gaming B850-Plus WiFi and the Gigabyte B850M Gaming X WiFi6E motherboards offer 7.1 audio channels, ensuring high-quality sound output for immersive experiences. Neither motherboard includes an S/PDIF Out port, so digital audio output through this connector is unavailable on either model.

When it comes to audio connectors, the Asus board provides 5 connectors, while the Gigabyte board offers 3. This gives the Asus motherboard more options for connecting audio devices like speakers, headphones, or microphones.

Overall, both boards feature the same 7.1 audio support and lack S/PDIF Out ports, but the Asus TUF Gaming B850-Plus WiFi offers a greater number of audio connectors compared to the Gigabyte B850M Gaming X WiFi6E.

Both the Asus TUF Gaming B850-Plus WiFi and the Gigabyte B850M Gaming X WiFi6E motherboards support several RAID configurations, including RAID 1, RAID 10 (1+0), RAID 5, and RAID 0. This provides users with flexible storage options for data redundancy and performance improvements. However, neither motherboard supports RAID 0+1, which is another RAID configuration that combines the features of RAID 0 and RAID 1.

Since both motherboards support the same set of RAID configurations and lack RAID 0+1 support, their storage capabilities are identical in this regard.

In summary, the Asus and Gigabyte motherboards offer the same RAID functionality, with support for RAID 1, RAID 10 (1+0), RAID 5, and RAID 0, but neither includes RAID 0+1 support.
