The ASRock X870 Steel Legend WiFi is the objective winner of this comparison, securing victory in 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 offering superior support for system RAM, this motherboard provides a more robust foundation for memory-intensive tasks compared to the MSI MAG B550 TOMAHAWK, which only outperformed its competitor in three specific categories.

Users who prioritize high-capacity memory configurations should select the ASRock X870 Steel Legend WiFi to take advantage of its doubled capacity limit. Conversely, the MSI MAG B550 TOMAHAWK is the better choice for those who specifically require more PCIe x1 slots, as it offers a 100% advantage in that area. Your final decision should depend on whether your build requires extensive memory overhead or additional expansion slots for peripheral cards.
