The ASRock X870 Steel Legend WiFi is the objective winner of this comparison, securing a lead in eight of the fourteen evaluated categories. Its most significant advantage over the competition is its memory slot configuration, which offers a 100% improvement in capacity. By providing double the slots, this motherboard establishes itself as the superior choice for users prioritizing system expandability and memory-intensive tasks over the more limited layout found in the alternative.

Choose the ASRock X870 Steel Legend WiFi if you require maximum memory expansion for your workstation or long-term build flexibility. Conversely, select the ASUS ROG STRIX X870-I GAMING WIFI if your primary requirement is connectivity, as it offers a 50% advantage in USB Type-C specifications. While the former excels in total memory support, the latter is the better option for users who specifically prioritize the increased availability of high-speed USB Type-C ports for their peripheral devices.
