The ASRock B850 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 competing board. By offering double the memory support, this motherboard provides a substantial technical lead in scalability for users who prioritize high-density RAM configurations for their system builds.

Choose the ASRock B850 Steel Legend WiFi if your primary requirement is maximizing system memory capacity for demanding workloads. Conversely, the ASUS TUF GAMING B550-PLUS is the better option for budget-conscious builders, as it offers a 30% advantage in MSRP. Selecting between these two components depends entirely on whether you prioritize the expanded memory ceiling provided by the ASRock model or the lower initial cost offered by the ASUS alternative.
