The socket is also expected^{[needs update]} 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^{[needs update]} 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]

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.^[5] 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.^[6]
