Intel's next-generation desktop processor socket will be the LGA1851. Leaked documents point to the next-generation socket being of identical dimensions to the current LGA1700, despite the higher pin-count, which could indicate cooler compatibility between the two sockets, much in the same way as the LGA1200 retained cooler-compatibility with prior Intel sockets tracing all the way back to the LGA1156. The current LGA1700 will service only two generations of Intel Core, the 12th Generation "Alder Lake," and the next-gen "Raptor Lake" due for later this year. "Raptor Lake" will be Intel's last desktop processor built on a monolithic silicon, as the company transitions to multi-chip modules.

Intel Socket LGA1851 will debut with the 14th Gen Core "Meteor Lake" processors due for late-2023 or 2024; and will hold out until the 15th Gen "Arrow Lake." Since "Meteor Lake" is a 3D-stacked MCM with a base tile stacked below logic tiles; the company is making adjustments to the IHS thickness to end up with an identical package thickness to the LGA1700, which would be key to cooler-compatibility, besides the socket's physical dimensions. Intel probably added pin-count to the LGA1851 by eating into the "courtyard" (the central gap in the land-grid), because the company states that the pin-pitch hasn't changed from LGA1700.
