Who each one is for
Buy the ASRock B650 PG Lightning for the most budget-conscious full-ATX AM5 builds and builders who don't need built-in WiFi, though it is not the pick for anyone who wants WiFi included without buying the separate variant and builds that want more than two M.2 slots. The ASUS Prime X870-P WiFi is the one to take for budget-focused builders who still want X870-level PCIe 5.0 features, though it is the wrong buy for overclockers who want TUF or ROG-level VRM certification and builders who need more than four M.2 slots. It is equally the pick for builds that want Wi-Fi 7 and USB4 at a Prime-series price.
