The picture shows Intel’s upcoming LGA1700/LGA 1800 sockets for the 12th-generation Alder Lake and 13th-generation Raptor Lake CPUs. The new 600 series chipset mainframe and the next generation 700 series motherboard will also use this socket.
Just yesterday we saw the first picture of the Z690 chipset, which will appear in the high-end 600 series motherboard lineup. The Intel LGA1700/1800 socket actually has more than 1700 pins, as the name suggests. Although Alder Lake CPUs will be equipped with 1700 metal contacts, CPUs compatible with sockets may be equipped with more contacts in the future, so 15R1 reserves an additional 100 pins for them. Now we have seen this slot in physical form and blueprints, but this is the first time we have seen it on an unreleased motherboard.
As far as we know, the 12th generation Alder Lake and the 13th generation Raptor Lake have confirmed support for LGA1700/1800 sockets. With the 14th generation Meteor Lake CPU, Intel may introduce new sockets due to the new small chip design, but this remains to be seen.
So as for the socket details, Intel adopted an asymmetrical design because the Alder Lake CPU is no longer square. The Alder Lake desktop CPU will be packaged in 37.5×45.0mm and supported by a V0 socket called LGA 1700. The new slot also changes the installation location to a 78x78mm grid instead of a 75x75mm grid. The height of Z has also been changed from 7.31mm for the previous LGA 12**/115* socket to 6.529mm.
This will cause two major changes. First, the CPU cooler must be properly installed on the CPU, which needs to be confirmed with the supplier before installation. Second, the cooler manufacturer needs a new mounting bracket to support Alder Lake and LGA 1700. As for the pin arrangement, the LGA 1700 socket will use a similar L-shaped design, with two contact areas similar to the existing LGA1200 socket, but only in a wider compartment, because it needs to accommodate more than 500 Pin.
