The MSI MAG X870 TOMAHAWK WIFI is the objective winner of this comparison, securing a lead in seven categories compared to two for the MSI PRO B860M-A WIFI. The most significant advantage offered by the MSI MAG X870 TOMAHAWK WIFI is its storage capacity, which features 100% more M.2 slots than the alternative. This substantial increase in connectivity provides a clear edge for users requiring extensive high-speed internal storage configurations for their system builds.

Users who prioritize maximum storage expansion should choose the MSI MAG X870 TOMAHAWK WIFI for its superior M.2 slot count. Conversely, the MSI PRO B860M-A WIFI is the better selection for those who specifically require additional expansion cards, as it provides a 100% advantage in available PCIe x1 slots. Selecting between these two motherboards depends entirely on whether your specific build requirements lean toward high-density storage solutions or the need for extra peripheral card connectivity.
