The ASRock X870E Taichi is the objective winner of this comparison, securing a lead in seven of the fourteen evaluated categories. Its most significant technical advantage over the competition is its inclusion of PCIe x1 slots, which offer a 100% improvement in quantity. While both motherboards share several identical specifications, the ASRock X870E Taichi provides a more robust overall configuration across the majority of the measured fields compared to the ASUS ROG STRIX X670E-E GAMING WIFI.

Users who prioritize connectivity for expansion cards should select the ASRock X870E Taichi for its superior PCIe x1 slot count. Conversely, the ASUS ROG STRIX X670E-E GAMING WIFI is the better choice for those who require additional PCIe x16 slots, as it provides a 50% advantage in that specific area. Your final decision should depend on whether your build configuration relies more heavily on the expansion capacity of x1 slots or the primary graphics and high-bandwidth slots.
