The ASRock X870 Steel Legend WiFi is the objective winner of this comparison, securing victories in two out of three evaluated specifications. Its most significant advantage is its maximum memory capacity, which is 100% higher than that of the alternative. By offering superior support for system memory, this motherboard provides a distinct technical edge for users prioritizing high-capacity configurations over other considerations.

Choose the ASRock X870 Steel Legend WiFi if your primary requirement is maximizing system memory for demanding workloads. Conversely, the MSI PRO B760M-A WIFI DDR4 is the better option for budget-conscious builders, as it holds a 52% advantage in MSRP. Selecting between these two components depends entirely on whether your build prioritizes the expanded memory ceiling offered by the former or the cost efficiency provided by the latter.
