LGA 7529
CPU socket designed by Intel From Wikipedia, the free encyclopedia
LGA 7529 is a zero insertion force flip-chip land grid array (LGA) socket designed by Intel which supports the Sierra Forest line of E-core only Xeon processors, designed for heavily multithreaded cloud workloads, as well as the Granite Rapids line of P-core only Xeon microprocessors, designed for mainstream usage. 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 were posted on January 31, 2023, by Yuuki_Ans. They showcased a dual LGA 7529 socket engineering sample motherboard. [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]
Intel launched the first processors to use the LGA 7529 socket on September 24, 2024, with their launch of their Granite Rapids line of CPUs.[7] This product line has two classes of CPUs: one using the twelve-channel LGA 7529 socket, referred to as the Xeon 6900P series, and the other using the smaller eight-channel LGA 4710 socket, referred to as the Xeon 6700P series.[8]
