The ASRock H670 Steel Legend is the objective winner of this comparison, securing more individual specification victories than its competitor. Its most significant technical advantage is the inclusion of PCIe x1 slots, which offer a 200% improvement in quantity compared to the alternative. This hardware configuration provides a distinct edge for users who prioritize expansion card connectivity and multi-peripheral support within their system build, establishing the board as the superior choice based on the total count of winning specifications.

Users who require extensive expansion capabilities should select the ASRock H670 Steel Legend to leverage its superior PCIe x1 slot count. Conversely, the Gigabyte B860M AORUS ELITE WIFI is the better option for those who prioritize system memory capacity, as it offers a 100% advantage in maximum memory support. Choosing between these two motherboards depends entirely on whether your specific build requirements lean toward additional expansion slots or a higher ceiling for total system memory.
