Intel Confirms Alder Lake & Raptor Lake Compatibility


While some signs from Intel pointed to compatibility between platforms for Intel’s upcoming Alder Lake and Raptor Lake processors, the evidence is now overwhelming. Based on a document filed with the industry standards committee SATA-IO, Intel’s upcoming 600-series chipsets will support both Alder Lake and Raptor Lake processors.

Last month an Intel contractor submitted compatibility testing results for the company’s upcoming “Alder-Raptor Lake PCH-S SATA Controller” to SATA-IO (via @Komachi_Ensaka), an organization that oversees and supports the SATA specification. The document covers Intel’s Platform Controller Hubs (PCHs) featuring 7AB0, 7ACB, 7A30, and 7A4B device IDs, which are probably the company’s 600-series chipsets for desktops and laptops.

The controller’s name confirms that Alder Lake and Raptor Lake CPUs can use the same chipsets, in this case, Intel’s 600-series PCHs. Meanwhile, compatibility with a chipset does not automatically mean drop-in compatibility of any Raptor Lake CPU with any Intel 600-series motherboard, as there are other considerations.
