The ASRock Z890 Taichi is the objective winner of this comparison, securing more individual specification victories than the ASRock X870 Steel Legend WiFi. While both motherboards share equal standing across the majority of their technical fields, the ASRock Z890 Taichi provides a significant advantage in storage expandability, offering 100% more M.2 slots than its counterpart. This superior connectivity capacity serves as the most impactful differentiator between the two hardware options.

Users prioritizing maximum storage configurations should select the ASRock Z890 Taichi to utilize its expanded M.2 slot count. Conversely, the ASRock X870 Steel Legend WiFi is the better choice for budget-conscious builders, as it holds a 55% advantage in MSRP. Choosing between these components depends entirely on whether your build requires extensive internal drive support or if you prefer to allocate your resources toward the more affordable option.
