Intel LGA-7529 Socket for “Sierra Forest” Xeon Processors Pictured

Intel’s upcoming LGA-7529 socket designed for next-generation Xeon processors has been pictured, thanks to Yuuki_Ans and Hassan Mujtaba. According to the latest photos, we see the massive LGA-7529 socket with an astonishing 7,529 pins placed inside of a single socket. Made for Intel’s upcoming “Birch Stream” platform, this socket is going to power Intel’s next-generation “Sierra Forest” Xeon processors. With Sierra Forest representing a new way of thinking about Xeon processors, it also requires a special socket. Built on Intel 3 manufacturing process, these Xeon processors use only E-cores in their design to respond to AMD EPYC Bergamo with Zen4c.

The Intel Xeon roadmap will split in 2024, where Sierra Forest will populate dense and efficient cloud computing with E-cores, while its Granite Rapids sibling will power high-performance computing using P-cores. This interesting split will be followed by the new LGA-7529 socket pictured below, which is a step up from Intel’s current LGA-4677 socket with 4677 pins used for Sapphire Rapids. With higher core densities and performance targets, the additional pins are likely to be mostly power/ground pins, while the smaller portion is picking up the additional I/O of the processor.
