The ASRock X870E Nova WiFi is the objective winner of this comparison, securing victory in eight of the thirteen evaluated categories. Its most significant technical advantage over the competition is its USB Type-C connectivity, which offers a 300% improvement in that specific specification. While the ASRock H670 Steel Legend manages to outperform the winner in two areas, including a 100% advantage in available PCIe x1 slots, it falls behind in the majority of the measured hardware metrics.

Users who prioritize modern peripheral connectivity and high-speed data transfer should select the ASRock X870E Nova WiFi for its superior USB Type-C integration. Conversely, the ASRock H670 Steel Legend remains the logical choice for builders who specifically require additional PCIe x1 slots for expansion cards. By evaluating these distinct advantages, you can align your motherboard selection with your specific connectivity needs or hardware expansion requirements rather than relying on general performance metrics.
