Xeon Sierra Forest, next-gen ‘atom’ data-center CPU

Hardware reviewer and leaker YuuKi_AnS has shared a picture of the LGA7529 socket for upcoming Xeon processors. 

YuuKi was one of the first to leak Intel’s Sapphire Rapids engineering samples. Although no photos of the Sierra Forest processor were published, a photo of the new socket design as well as next-gen motherboard have emerged. The socket is labeled as LGA-7529, indicating an increase in pin count over Sapphire Rapids’s 4677 design.

What is part of the upcoming “Birch Stream” platform, Xeon Sierra Forest is a new series of Xeon processors designed with so-called Efficient cores. This is a new segment of Intel data center CPUs that is likely to compete with AMD EPYC Bergamo featuring Zen4c cores.

This ‘atom’ based Xeon processor is opening Intel’s dual track P/E core roadmap. The processors based on this silicon will exclusively use smaller cores in an effort to increase the maximum core count for these CPUs.

According to Intel, Sierra Forest is to use Intel 3 fabrication process, and it will be optimized for high-density and ‘ultra-efficient’ computing in the cloud systems.

Recently, Intel confirmed that Sierra Forest will launch in 2024 alongside Granite Rapids. This will be the first Intel will split its Xeon lineup between P-Core and E-Core designs.
