Intel Alder Lake-S will be incompatible with LGA1200 heatsinks

Information comes in that the LGA1700 socket will not be compatible with LGA1200 heatsinks, something that we already imagined. The change of platform is inevitable, so its 78 × 78 measurements do not match the 75 × 75 of the LGA1200.

This news is more logical than the incompatibility between LGA115X and LGA1200, two sockets that were practically identical and whose design was deliberately rectified in order to achieve an incompatibility. Heatsink manufacturers solved this by offering adapters to their customers, but we understand that LGA1700 is not compatible with LGA1200 because there are many changes that are going to be introduced.

LGA1700 will be incompatible with LGA1200, similar to LGA2066!

Gradually, they get to know details about the dimensions of the next socket, and sources confirm that this LGA1700 will not be compatible with the heatsinks of LGA1200. The rationale for this is that the dimensions of the LGA1200 are 75 x 75 mm, while the LGA1700 would have a size of 78 x 78 mm.

In this sense, it is closer to LGA2011 or LGA2066, whose measurements are 80 x 80 mm, but we do not believe that they will be compatible with this platform. From the outset, the LGA1700 heatsinks will cool the Intel Alder Lake-S processors, characterized by coming with a big.LITTLE architecture and a 10nm design.

The 12th generation of Intel Core processors will be composed of mixed cores: some high performance (Golden Cove) and others high efficiency (Gracemont). However, not all processors in this family will come with high-efficiency cores, as indicated by leaks related to the i5-12600K: it would only have 6 high-performance cores.

The main novelties of the LGA1700 socket will be its support for DDR5 RAM and the integration of PCI-Express 5.0 natively. Details on the first boards to come with LGA1700 are not yet known, but an Intel 600 series is expected in their chipsets. We make it clear that Z590 motherboards will not be compatible with Alder Lake-S processors because it is a chipset for LGA1200.

We don't know how many generations Intel Core the LGA1700 socket will house, but Intel has already announced that its life will be much longer than the LGA1200 socket, why? To satisfy Intel users who have opted for these last 2 generations of chips (Comet Lake-S and Rocket Lake-S).
