The Gigabyte B850 GAMING X is the objective winner of this comparison, securing more individual specification victories than its competitor. Its most significant advantage is the inclusion of PCIe x16 slots, which offer a 100% improvement over the alternative. This hardware configuration provides a clear edge in connectivity and expansion potential for users who prioritize motherboard versatility and future-proofing their system builds with additional high-speed components.

Users who require maximum expansion capabilities should choose the Gigabyte B850 GAMING X to leverage its superior slot configuration. Conversely, the MSI PRO B850M-A WIFI is the better option for budget-conscious builders, as it holds a 17% advantage in MSRP. Selecting between these two motherboards depends entirely on whether your priority is the increased hardware connectivity provided by the former or the cost efficiency offered by the latter.
