Information submitted by Intel to SATA-IO confirms the compatibility between Alder Lake and Raptor Lake
Although there is early news that in the mainstream consumer market, Intel will launch the 12th-generation Core series processor code-named Alder Lake at the end of 2021, and there will be no difference between the 13th-generation Core series processor code-named Raptor Lake launched in 2022. This processor will use the big.LITTLE hybrid architecture, 8 high-performance Golden Cove and 8 high-efficiency Gracemont cores, using 10nm process manufacturing, support DDR5 memory, may also introduce PCIe 5.0 standard.
The reason is that Alder Lake has introduced many new technologies. Raptor Lake will not update the architecture, but will only make appropriate optimization adjustments, such as improving the cache structure and obtaining a new DLVR power supply system. Both will continue to use the LGA 1700 base, and the motherboards used are compatible
Recently, Twitter user @KOMACHI_ENSAKA discovered that Intel had submitted information about SATA about the upcoming PCH to the SATA-IO organization. The document covers some IDs of the PCH series of Alder Lake and Raptor Lake, namely 7AB0 to 7ACB and 7A30 to 7A4B, confirming that the two processors can use the same chipset. Of course, this does not mean that it must be fully compatible, and other factors may also be considered. In fact, Intel has not yet confirmed that Raptor Lake is the successor of Alder Lake. If it were not for the disclosure of other documents, I always thought that Meteor Lake, which was manufactured using the 7nm process, would be the successor of Alder Lake.
Earlier news pointed out that on the desktop platform, Alder Lake only supports the PCIe 4.0 standard, and the 600 series chipset also only supports the PCIe 4.0 standard. If this rumor is correct, then Intel may only support the PCIe 5.0 standard in the 700-series chipset.
