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 Gigabyte X870E AORUS MASTER is the inclusion of PCIe x1 slots, which represents a 100% improvement in that specific category. While both motherboards share identical specifications across the majority of the evaluated fields, the ASRock X870E Taichi provides superior connectivity options for users requiring additional expansion card support.

Users who prioritize maximum expansion card connectivity should choose the ASRock X870E Taichi for its doubled PCIe x1 slot capacity. Conversely, the Gigabyte X870E AORUS MASTER is the better selection for those who require more PCIe x16 slots, as it offers a 50% advantage in that area. Since both boards are otherwise evenly matched across most technical specifications, the final decision rests entirely on whether your specific build configuration demands more x1 or x16 expansion lanes.
