The Intel 7 manufacturing process is used for the 12th generation “Alder Lake” and the newer 13th generation processors but with significant gains in efficiency. Raptor Lake will work with existing motherboards of LGA 1700 Socke to offer an upgrade path for Alder Lake customers, albeit the boards may need a firmware update to be compatible. Using the same socket, it seems that the new motherboards will be technologically limited in how they connect to CPUs. Intel included some LGA 1700 future-proofing in their motherboard designs after promising that the socket would remain popular for many years.
