The ASRock Z890 Taichi is the objective winner of this comparison, securing a lead in eight out of thirteen evaluated specifications. Its most significant advantage over the ASRock B760M PG Lightning is the inclusion of M.2 slots, which provides a 200% increase in capacity for high-speed storage expansion. While the ASRock B760M PG Lightning offers a 100% advantage in PCIe x1 slots, the ASRock Z890 Taichi dominates the overall feature set across the majority of measured categories.

Users requiring extensive storage configurations should prioritize the ASRock Z890 Taichi to leverage its superior M.2 slot count. Conversely, the ASRock B760M PG Lightning is the appropriate choice for builders who specifically need the additional PCIe x1 connectivity provided by that board. Selecting between these two components depends entirely on whether your build demands maximum storage expandability or the specific peripheral support offered by the higher number of PCIe x1 slots.
