The Gigabyte B860 AORUS ELITE WIFI is the objective winner of this comparison, securing more victories across the evaluated specifications. Its most impactful advantage is the inclusion of additional PCIe x16 slots, which represents a 100% improvement over the ASRock B760M PG Lightning. This hardware configuration provides superior expansion capabilities for users requiring multiple high-bandwidth add-in cards, establishing the Gigabyte board as the more versatile option for complex system builds.

Users prioritizing high-speed expansion should choose the Gigabyte B860 AORUS ELITE WIFI for its doubled PCIe x16 slot capacity. Conversely, the ASRock B760M PG Lightning is the better selection for those who specifically require more PCIe x1 slots, as it offers a 100% advantage in that category. Selecting between these two motherboards depends entirely on whether your specific hardware configuration relies on the primary x16 interface or the smaller x1 expansion slots.
