The ASRock B850 Steel Legend WiFi is the objective winner of this comparison, securing a higher number of superior specifications across the evaluated categories. Its most significant advantage is its maximum memory capacity, which is 100% better than that of the competing board. This substantial increase in supported memory provides a clear edge for users who prioritize system capacity and high-density configurations over other hardware features.

Users who require maximum memory support should choose the ASRock B850 Steel Legend WiFi for their build. Conversely, those who prioritize expansion capabilities should opt for the ASUS ROG STRIX Z590-E GAMING WIFI, as it offers a 100% advantage in the number of available PCIe x1 slots. Selecting between these two motherboards depends entirely on whether your specific workflow demands greater memory overhead or additional room for peripheral expansion cards.
