The ASRock X870E Taichi is the objective winner of this comparison, securing more victories across the evaluated technical specifications. Its most significant advantage over the competition is the inclusion of PCIe x1 slots, which represent a 100% improvement in that specific connectivity category. While both motherboards share many identical features, this hardware lead establishes the ASRock X870E Taichi as the more versatile option for users requiring additional expansion card support within their system build.

Users who prioritize expansion capabilities should select the ASRock X870E Taichi to take advantage of its superior PCIe x1 slot configuration. Conversely, those who rely heavily on high-speed peripheral connectivity should choose the MSI MPG X870E CARBON WIFI, as it offers a 50% advantage in USB Type-C port capacity. Selecting between these two components depends entirely on whether your specific workflow demands more internal expansion slots or a greater number of external USB Type-C connections.
