According to Intel's development resources website, it has been confirmed that the Alder Lake-S CPU series will actually support a new "LGA 1700" socket. The resources website lists new information about the next Alder Lake series.
Intel now lists the LGA1700 socket on its official resources website, which is a direct confirmation from the company regarding Alder lake-S that will require a new CPU socket. Alder Lake-S would be a direct successor to Rocket Lake-S; there is also a new entry called the Alder Lake-P series. At this time it is not known what the true purpose of the Alder Lake P processor range is. The Intel Atom server series that had up to 24 cores (codenamed "Snow Ridge") is the latest CPU line to use the P suffix.
User Komachi_Ensaka on Twitter recalled earlier in January that this new socket will be larger than the LGA1151 /1200 sockets (37.5 mm x 37.5 mm). The exact dimensions (45.0 mm x 37.5 mm) have also been outlined, revealing that Intel Alder Lake-S will be a successor to Comet/ Rocket Lake-S and will present a new LGA 1700 socket.
This socket will have support for at least three generations of Intel CPUs. More importantly, Alder Lake-S is expected to unveil a new "big core/small core" architecture, with Golden Cove and Gracemont cores.
Alder Lake-S will be the first Intel architecture to offer the big.little ARM approach to desktop processors. These next CPUs would have up to 16 cores, of which 8 would be "Big", and the rest would use the "Small" architecture.
According to one report, it is now assumed that these architectures are Golden Cove (successor to Willow Cove) and Gracement (Tremont's successor) respectively. Willow Cove is expected to appear in the next series of Rocket Lake-S processors. The LGA 1700 socket will support 3 generations of Intel CPUs. This is something new for Intel because until now the company is known to support sockets only for a short period of time. This new socket will support the "DDR5" memory, so it will compete with the AMD AM5 socket in terms of platform longevity.
