The ASRock X870E Taichi is the objective winner of this comparison, securing more individual specification victories than its competitor. The most impactful advantage offered by the ASRock X870E Taichi is its superior power delivery system, which features VRM phases that are 29% better than those found on the alternative board. This hardware configuration provides a distinct technical edge in power stability and thermal management for the processor during sustained high-load operations.

Users prioritizing robust power delivery and system stability should choose the ASRock X870E Taichi for their build. Conversely, the Gigabyte Z890 AORUS MASTER is the better selection for enthusiasts who specifically require the highest possible memory performance, as it holds a 12% advantage in maximum memory speed. Selecting between these two motherboards depends entirely on whether your primary requirement is the enhanced power phase design of the ASRock or the increased memory frequency support of the Gigabyte.
