The Gigabyte X870E AORUS XTREME AI TOP is the objective winner of this comparison, securing more victories across the evaluated technical specifications. Its most impactful advantage over the ASRock H670 Steel Legend is its superior USB Type-C connectivity, which offers a 400% improvement in that specific category. While both motherboards share several identical features, the Gigabyte option provides a more robust set of modern specifications for users prioritizing high-speed peripheral integration.

Users who require extensive USB Type-C connectivity should choose the Gigabyte X870E AORUS XTREME AI TOP to take advantage of its significant lead in that area. Conversely, the ASRock H670 Steel Legend is the better selection for those who specifically prioritize expansion through PCIe x1 slots, where it maintains a 100% advantage over the alternative. Selecting between these two components depends entirely on whether your build demands more modern port density or additional legacy expansion slots.
