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, this lead in expansion connectivity establishes the ASRock X870E Taichi as the more versatile option for users requiring additional peripheral support.

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