The Gigabyte Z790 AORUS ELITE AX is the objective winner of this comparison, securing a higher count of superior specifications across the evaluated fields. Its most impactful advantage is the inclusion of PCIe x16 slots, which offer a 200% improvement over the ASRock B850M PG Riptide WiFi. This hardware configuration provides a significant edge in connectivity and expansion potential for high-performance components that rely on these specific slots for optimal operation.

Users prioritizing high-bandwidth expansion should choose the Gigabyte Z790 AORUS ELITE AX to leverage its superior PCIe x16 slot capacity. Conversely, the ASRock B850M PG Riptide WiFi is the better selection for those who specifically require more PCIe x1 slots, as it provides a 100% advantage in that category. Selecting between these two motherboards depends entirely on whether your build requires the high-speed lane density of the former or the specialized slot configuration of the latter.
