The ASRock X870 Steel Legend WiFi is the objective winner of this comparison, securing more total spec victories than its counterpart. Its most significant advantage is the inclusion of additional PCIe x16 slots, which offer a 100% improvement over the ASRock B850M PG Riptide WiFi. This hardware configuration provides a clear lead in expansion capabilities for high-bandwidth components, establishing the Steel Legend as the more robust option for users requiring extensive connectivity for demanding hardware configurations.

Users who prioritize high-performance expansion should select the ASRock X870 Steel Legend WiFi to leverage its superior PCIe x16 slot count. Conversely, the ASRock B850M PG Riptide WiFi is the better choice for those who specifically require more PCIe x1 slots, as it provides a 100% advantage in that category. Choosing between these two motherboards depends entirely on whether your specific build requirements favor the primary expansion slots or the secondary connectivity options provided by the smaller slots.
