The ASRock X870E Taichi is the objective winner of this comparison, securing a lead in six out of fourteen measured specifications. Its most significant advantage over the alternative is its superior configuration of PCIe x1 slots, which offers a 100% improvement in capacity. While the ASRock B850 Steel Legend WiFi holds its own across seven tied categories, it ultimately falls behind in total feature density when measured against the more robust hardware layout of the Taichi.

Users prioritizing budget efficiency should select the ASRock B850 Steel Legend WiFi, as it provides a 54% advantage in MSRP compared to the higher-tier model. Conversely, the ASRock X870E Taichi is the correct choice for enthusiasts who require the maximum number of PCIe x1 slots for expansion cards. By choosing based on these specific advantages, builders can align their motherboard selection with either strict cost constraints or the need for extensive peripheral connectivity.
