The ASRock X870E Taichi is the objective winner of this comparison, securing more individual specification victories than its competitor. Its most significant advantage over the ASUS ROG CROSSHAIR X870E HERO is the inclusion of PCIe x1 slots, which represents a 100% improvement in that specific connectivity category. While both motherboards share identical specifications across the majority of tested fields, the Taichi provides superior expansion capabilities for users requiring additional peripheral support through those specific slots.

Users who prioritize maximum expansion card connectivity should choose the ASRock X870E Taichi for its superior PCIe x1 slot configuration. Conversely, the ASUS ROG CROSSHAIR X870E HERO is the better option for builders who require higher storage density, as it offers a 25% advantage in the number of available M.2 slots. Selecting between these two boards depends entirely on whether your specific build configuration demands more traditional expansion cards or increased high-speed internal storage capacity.
