LGA 7529 is a zero insertion force flip-chip land grid array (LGA) socket designed by Intel that used by Sierra Forest, a line of E-Core Xeon processors designed for heavily multithreaded cloud workloads, and Granite Rapids, the all P-Core mainstream Xeon microprocessors. The socket is also expected to support the mainstream successor to Granite Rapids, Diamond Rapids.[1] The first pictures of the Intel 'Birch Stream' platform, a two socket engineering motherboard featuring dual LGA 7529 sockets, was posted on January 31, 2023, by Yuuki_Ans.[2]

The Birch Stream platform is expected to support 12 channels of DDR5 memory per socket, for a total of 24 channels of DDR5 memory on a dual socket system.[3][4]

At OCP Summit 2023, Intel announced that Sierra Forest would be targeting a 1H 2024 launch.[4] The first line of Sierra Forest SKUs launched was the 6700E series, which uses the LGA 4710 socket, rather than the LGA 7529 socket.[5][6] The Xeon 6900P series launched at the end of Q3 2024, on September 24th, 2024.[7]

Intel launched the first processors to use the LGA 7529 socket on September 24th, 2024, with their launch of their Granite Rapids line of CPUs.[7] This product line has two classes of CPU, one which uses the twelve-channel LGA 7529 socket, referred to as the Xeon 6900P series, and the other which uses the smaller eight-channel LGA 4710 socket referred to as the Xeon 6700P series.[8]
