In a recent AMD lab tour documented by Gamers Nexus, AMD engineers showed off some wild equipment used to test chipset functionality on AM5 motherboards. The equipment comes in the form of slot-able, stackable chipset cards that are capable of simulating all of AMD's chipsets, including B650 all the way to X670E, and are capable of creating any I/O configuration motherboard manufacturers might put on their AM5 boards.
According to AMD's engineers, the chipset cards operate on a reference AM5 motherboard without its own chipset, that has additional PCIe plugs for housing the custom AMD chipset cards. The chipset cards come with a plethora of additional I/O connectivity, including SATA ports, several different versions of USB, M.2 storage, ethernet, and more. AMD's chipset cards can also be stacked on top of each other to add even more connectivity.
