A leak of the Momomo_US and Komachi_Ensaka accounts show that the successor of the LGA 1200 socket will be LGA 1700, and that would be the Alder Lake-S platform, which in addition to a new socket will bring a new rectangular format for the processors, which were normally square at least on the Intel side.
As Komachi revealed, Alder Lake-S processors will have dimensions of 45×37.5mm, while current processors such as the i9-9900K have dimensions of 42.5 × 42.5mm. This rectangular design and the rather massive number of pins are most likely due to a design change towards a multi-die design, housing two DIEs at 10nm to compete better with the AMD platform.
