Intel’s Alder Lake and Raptor Lake parts get a SATA PCH compliance listing
Tipster @KOMACHI_ENSAKA recently spotted what appears to be PCH (platform controller hub) compliance listings for both Intel's confirmed 12th-Gen Alder Lake CPUs and their unconfirmed 13th-Gen Raptor Lake CPUs. Alder Lake parts were identified by device IDs from 7AB0 to 7ACB. Raptor Lake parts in the compliance list had device IDs between 7A30 and 7A4B.
The PCH compliance listings on the SATA IO website lend credence to the idea that Raptor Lake will be compatible with LGA 1700 boards running Alder Lake hardware. Unlike the jump from Rocket Lake to Alder Lake, this means that Alder Lake owners have a viable upgrade path. Earlier rumors indicated that Raptor Lake would, in many ways resemble an enhanced Alder Lake, with potentially twice as many high-performance cores, and support for DDR5 memory.
Alder Lake is Intel's first stab at a 10nm desktop part. If IPC and core count gains from Golden Cove and Raptor Cove bear out, Alder Lake and Raptor Lake could have serious staying power relative to Rocket Lake.
