The ASRock X870 Steel Legend WiFi is the objective winner of this comparison, securing a lead in six of the fourteen evaluated categories. Its most significant advantage over the competition is the inclusion of USB Type-C connectivity, which offers a 100% improvement in that specific specification. While both motherboards share several identical features, the ASRock X870 Steel Legend WiFi provides a more robust set of modern interface options for users prioritizing high-speed peripheral support.

Users who require superior USB Type-C connectivity should select the ASRock X870 Steel Legend WiFi for their build. Conversely, the MSI MAG X670E TOMAHAWK WIFI is the better choice for those who prioritize expansion capabilities, as it holds a 100% advantage in the number of available PCIe x1 slots. Choosing between these two components depends entirely on whether your workflow relies more heavily on modern external data transfer or internal hardware expansion.
