The ASRock X870E Nova WiFi is the objective winner of this comparison, securing a lead in six out of fourteen measured specifications. Its most impactful advantage is the USB Type-C connectivity, which offers a 100% improvement over the alternative. While the ASRock B850 Steel Legend WiFi holds its own across seven tied categories, it ultimately falls behind in total feature count compared to the more robust capabilities provided by the X870E Nova WiFi.

Users who prioritize maximum peripheral connectivity and advanced interface options should choose the ASRock X870E Nova WiFi for its superior USB Type-C support. Conversely, the ASRock B850 Steel Legend WiFi is the better selection for budget-conscious builders, as it provides a 34% advantage in MSRP. Selecting between these two motherboards depends entirely on whether your build requires the expanded connectivity of the higher-tier model or the cost efficiency of the B850 variant.
