Yesterday, Intel confirmed that it plans to release new generation Arrow Lake processors in 2024, which will also appear in the desktop segment. They will also introduce the new LGA 1851 socket, which was originally intended for Meteor Lake-S desktop chips, but the manufacturer refused to release it.

An interactive 3D model of the Intel LGA 1851 socket appeared on the website today Igor’s LAB — Drawings of the ILM (Independent Loading Mechanism) mounting mechanism and a model of the processor itself are also published there. As part of its competition with AMD, Intel has decided to expand support for PCIe 5.0: While the previous LGA 1700 was limited to 16 lines of this interface, LGA 1851 already offers 16+4 lines – the latter are intended for SSDs.
On existing platforms, with only 16 lanes, the simultaneous use of PCIe 5.0 graphics cards and SSDs is not possible. In practice, this restriction does not apply: Neither NVIDIA, AMD nor Intel have desktop graphics for PCIe 5.0.
The Arrow Lake family will produce processors that offer up to eight powerful P-cores and up to 16 E-cores. With the release of the subsequent Panther Lake family, the number of cores could increase. It is also assumed that the new platform will only support DDR5 memory and DDR4 will finally become a thing of the past. The LGA 1851 socket works with Intel 800 series chipsets: Z890, B860, H810, W880 and Q870. Finally, the same coolers that were used on the LGA 1700 will be suitable for the new socket: the dimensions of the processor case remain the same, but the heat distribution covers (IHS) change slightly – this became known when studying the technical sample of the canceled Meteor Lake -S chips.
