Some time ago we saw how ASRock showed a system to upgrade a B650 motherboard into an X670 motherboard thanks to the dual-chip system used by these second company chipsets. At first there was not much movement in this regard, but we can see how some improvement options are emerging thanks to this scheme.
As I noted, B650 motherboards make use of one AMD Promontory 21 chip, while X670 motherboards make use of two AMD Promontory 21 chipsso dedicating a bus to connecting two chipsets together allows, for practical purposes, to convert one motherboard into another.
It is because of that ASUS has been able to carry this out on its ASUS X670E-I GAMING WIFI, although it is not clear if this implementation will feature the chipset in the box, since the name of the motherboard does not denote its minimum configuration, so we could find ourselves in the situation of buying a motherboard that we think is an X670 to actually be a B650.
This would be the opposite case of ASRock, where this additional board was installed to convert one of its B650 motherboards -and sold as such- into X670.
