The ASRock X870 Steel Legend WiFi is the objective winner of this comparison, securing victory across seven of the thirteen evaluated specifications. Its most significant technical advantage is its maximum memory capacity, which is 100% higher than that of the alternative. By outperforming the competition in a majority of the measured categories, this motherboard establishes itself as the more robust option for users prioritizing modern hardware standards and expanded system memory support.

Users who require the highest possible memory capacity should choose the ASRock X870 Steel Legend WiFi for their build. Conversely, the MSI MAG B550 TOMAHAWK remains the superior choice for those who specifically prioritize expansion, as it offers a 100% advantage in the number of available PCIe x1 slots. Selecting between these two components depends entirely on whether your workflow demands greater system memory overhead or additional physical slots for peripheral expansion cards.
