The MSI MEG X870E ACE MAX is the objective winner of this comparison, securing more total spec victories across the evaluated fields. Its most significant technical advantage is its LAN capability, which performs 300% better than that of the Gigabyte B860M AORUS ELITE WIFI. This superior networking throughput represents the primary performance gap between the two motherboards, establishing the MSI board as the more robust option for users prioritizing high-speed connectivity and advanced integrated features.

Users who require maximum networking performance should choose the MSI MEG X870E ACE MAX for its substantial LAN advantage. Conversely, the Gigabyte B860M AORUS ELITE WIFI is the better selection for those who specifically need additional expansion options, as it offers 100% more PCIe x1 slots than its competitor. Selecting between these two components depends entirely on whether your build prioritizes high-bandwidth network connectivity or the physical capacity for extra PCIe expansion cards.
