The Gigabyte B850 GAMING X is the objective winner of this comparison, securing more individual specification victories than its competitor. Its most significant advantage lies in its expansion capabilities, offering 100% more PCIe x16 slots than the alternative. This hardware configuration provides a clear edge for users who prioritize internal connectivity and multi-card setups, making it the superior choice for those requiring additional physical expansion room within their system build.

Choose the Gigabyte B850 GAMING X if your primary requirement is maximizing PCIe x16 slot availability for add-in cards. Conversely, select the MSI PRO B850M-A WIFI if your setup necessitates integrated wireless connectivity, as it offers a 100% advantage in Wi-Fi capability. Your decision should depend entirely on whether your specific build demands more physical expansion ports or the convenience of built-in wireless networking features.
