Intel confirms the compatibility of Alder Lake and Raptor Lake

Although some Intel’s signs indicate compatibility Between Intel’s upcoming Alder Lake and Raptor Lake processor platforms, the evidence is now overwhelming. According to documents submitted to the Industry Standards Committee SATA-IO, Intel’s upcoming 600 series chipset will support both Alder Lake and Raptor Lake processors.

Last month, Intel’s contractor submitted the company’s upcoming “Alder-Raptor Lake PCH-S SATA controller” compatibility test results for SATA interface (by @Komachi_Ensaka), an organization that oversees and supports the SATA specification. This document covers Intel’s Platform Controller Hub (PCH), with 7AB0, 7ACB, 7A30, and 7A4B device IDs, which may be the company’s 600 series chipsets for desktop and laptop computers.

The name of the controller confirms that Alder Lake and Raptor Lake CPUs can use the same chipset, in this case Intel’s 600 series PCH. At the same time, compatibility with the chipset does not automatically mean the direct compatibility of any Raptor Lake CPU with any Intel 600 series motherboard, because there are other considerations.
