Gigabyte B860M Aorus Elite VS MSI Pro B840-P WiFi

The most fundamental distinction here is platform compatibility: the Gigabyte B860M Aorus Elite uses an LGA 1851 socket paired with Intel's B860 chipset, while the MSI Pro B840-P WiFi uses an AM5 socket with AMD's B840 chipset. These two boards are entirely incompatible with each other's processors, so your CPU choice — Intel Arrow Lake or AMD Ryzen 9000 series — will determine which board is even relevant to you. Neither decision is objectively superior; it comes down to the broader ecosystem you are investing in.

Beyond platform, the boards diverge meaningfully in form factor and connectivity. The Gigabyte is a compact Micro-ATX (244 × 244 mm), making it a better fit for smaller builds or cases with tight clearances. The MSI is a full ATX (304.8 mm wide), offering more physical space for expansion slots and airflow routing in mid-tower or larger cases. On wireless connectivity, the MSI holds a clear practical edge: it includes both Wi-Fi and Bluetooth out of the box, while the Gigabyte offers neither — a significant omission in 2025 that would require an add-in card or USB adapter for wireless use.

Both boards share HDMI 2.1 output, dual BIOS, RGB lighting, a 3-year warranty, and are rated as easy to overclock — so neither has an edge on firmware resilience or longevity. However, the MSI also supports easy BIOS reset while the Gigabyte does not, which is a minor but real convenience advantage during troubleshooting. Overall, if wireless connectivity and BIOS accessibility matter to your build, the MSI Pro B840-P WiFi has a tangible edge in this category — provided you are building on the AMD platform.

Both the Gigabyte B860M Aorus Elite and the MSI Pro B840-P WiFi support a maximum memory capacity of 256GB, with no difference in this regard. Both motherboards also come with 4 memory slots and support DDR5 memory, with dual memory channels available on each board.

When it comes to memory speed, the Gigabyte model offers a higher maximum RAM speed of 6400 MHz compared to the MSI Pro's 5600 MHz. The Gigabyte board also supports higher overclocked RAM speeds, reaching 9200 MHz, while the MSI Pro is limited to 8000 MHz.

Neither motherboard supports ECC memory, so both are intended for consumer-grade rather than enterprise-level memory error correction.

The Gigabyte B860M Aorus Elite and the MSI Pro B840-P WiFi differ in several port categories. The Gigabyte board offers more USB 3.2 Gen 2 (USB-A) ports, with 2 compared to the MSI Pro's 1. In contrast, the MSI Pro offers 1 USB 3.2 Gen 2 (USB-C) port, whereas the Gigabyte model has none. Both motherboards include 4 USB 2.0 ports, and neither offers USB 3.2 Gen 2x2 or USB 4 ports.

For video outputs, both motherboards provide an HDMI output. However, the Gigabyte model includes a DisplayPort output, while the MSI Pro lacks one. Neither board has a VGA connector or eSATA ports, and both omit DVI outputs.

Both motherboards feature 1 RJ45 port for Ethernet connectivity. The Gigabyte B860M Aorus Elite has USB Type-C support, but the MSI Pro includes both a USB Type-C (USB 3.2 Gen 2) and Thunderbolt 4 ports, giving it some additional flexibility for high-speed connectivity.

The Gigabyte B860M Aorus Elite and the MSI Pro B840-P WiFi share several similar connector features. Both motherboards offer 2 USB 3.2 Gen 1 ports, 4 USB 2.0 ports, and 2 USB 3.0 ports through expansion. They also both have 4 SATA 3 connectors and 6 fan headers, ensuring ample connectivity for storage and cooling solutions.

When it comes to M.2 sockets, the Gigabyte B860M Aorus Elite provides 3, while the MSI Pro B840-P WiFi offers 2, giving the former a slight advantage for expansion. Both motherboards feature a TPM connector for enhanced security. Neither board includes U.2 sockets, and both lack mSATA connectors, as well as SATA 2 connectors.

Overall, the key differences are the additional M.2 socket on the Gigabyte B860M Aorus Elite and the otherwise matching feature set between the two boards.

The Gigabyte B860M Aorus Elite and the MSI Pro B840-P WiFi differ in their expansion slot configurations. The Gigabyte model features 1 PCIe 5.0 x16 slot and 1 PCIe x4 slot, while the MSI Pro offers 1 PCIe 4.0 x16 slot and 1 PCIe 3.0 x16 slot. Both motherboards have no PCIe x8 or PCI slots.

Additionally, the Gigabyte B860M Aorus Elite does not have any PCIe 3.0 x16 slots or PCIe x1 slots, while the MSI Pro B840-P WiFi provides 3 PCIe x1 slots, which gives it more flexibility for smaller expansion cards.

Overall, the Gigabyte board is focused on a more advanced PCIe 5.0 x16 slot, while the MSI board provides more options for smaller expansion cards with its PCIe x1 slots and an older PCIe 4.0 x16 slot.

Both the Gigabyte B860M Aorus Elite and the MSI Pro B840-P WiFi support 7.1 audio channels, providing high-quality sound. The key difference between them lies in the audio connectors and S/PDIF Out port. The Gigabyte board has 2 audio connectors and includes an S/PDIF Out port, while the MSI Pro offers 3 audio connectors but lacks the S/PDIF Out port.

Therefore, while both motherboards offer similar audio channel support, the Gigabyte model offers more comprehensive audio output options with the inclusion of the S/PDIF Out port, whereas the MSI Pro provides one extra audio connector.

The Gigabyte B860M Aorus Elite and the MSI Pro B840-P WiFi both support RAID 1, RAID 10 (1+0), and RAID 0 configurations, allowing users to choose from several storage array options for redundancy or performance. However, the Gigabyte model also supports RAID 5, offering an additional option for fault tolerance and data protection, which the MSI Pro does not.

Neither motherboard supports RAID 0+1, but this feature is typically less commonly used. Overall, the key difference between the two is the RAID 5 support available on the Gigabyte B860M Aorus Elite.
