Today, Intel’s LGA-17XX/LGA-18XX compatible socket cover images have been leaked on Twitter by @momomo_us. The new leaked images give us some idea of the compatibility between the upcoming LGA-1700 and the LGA-1800 sockets. It’s worth noting that this is the first-ever appearance of the LGA-1800 sockets.
Igor Wallossek, in his preview of Intel’s Alder Lake-S with boxed cooler and cryocooler including Peltier element, gave his overview of the LGA-1700/1800 socket.
With the new LGA1700 and LGA1800 sockets, Intel also introduces a new mounting system and deliberately changes the hole patterns for the screw and backplate. With the increased distances of the holes by a few millimeters, one wants to understandably avoid that someone puts an old cooler on the new system. Because not only the structure width of the new CPUs becomes smaller, but also the height of the complete package.
According to sources, Intel’s “Alder Lake”, and its successor titled “Raptor Lake”, will be utilizing the LGA-1700 series socket while LGA 1800 could be used by Meteor Lake. AMD’s “Raphael” on the other hand will be using the LGA-1718 socket.
