The ASRock X870 Steel Legend WiFi is the objective winner of this comparison, securing victory in eight of the fourteen evaluated categories. Its most significant technical advantage is its maximum memory capacity, which is 100% higher than that of the alternative. By outperforming the MSI MAG B560 TOMAHAWK WIFI in the majority of measured specifications, the ASRock X870 Steel Legend WiFi establishes itself as the more capable component for users prioritizing high-capacity memory configurations.

Users who require extensive system memory for demanding workloads should choose the ASRock X870 Steel Legend WiFi to leverage its superior capacity. Conversely, the MSI MAG B560 TOMAHAWK WIFI is the better selection for those who specifically prioritize expansion, as it offers a 100% advantage in available PCIe x1 slots. Selecting between these two motherboards depends entirely on whether your build requires maximum memory support or a higher density of PCIe x1 connectivity.
