The ASRock X870E Taichi is the objective winner of this comparison, securing a lead in eight out of eleven evaluated specifications. Its most significant technical advantage is its LAN capability, which outperforms the alternative by 400 percent. While the Gigabyte A620M DS3H holds a 100 percent advantage in the number of PCIe x1 slots, the superior connectivity and overall feature set of the ASRock X870E Taichi make it the more robust choice for high-performance requirements.

Users prioritizing advanced networking speeds should select the ASRock X870E Taichi to leverage its substantial LAN advantage. Conversely, the Gigabyte A620M DS3H is the appropriate choice for those who specifically require additional PCIe x1 slots for expansion cards. By focusing on these distinct hardware strengths, builders can align their motherboard selection with their specific connectivity or expansion needs rather than relying on general performance metrics.
