Intel's next-generation LGA 7529 socket which will be used by future Xeon CPUs with up to 512 cores has been pictured in insane detail.
Intel LGA 7529 Socket With Support For Up To 512 Core Xeon CPUs Pictured On Engineering Motherboard
Although we have already seen the Intel LGA 7529 socket in close-up shots, the new pictures come from an engineering motherboard that was acquired by Bilibili content creator, @不拉更的Harry & Machine Soul. The motherboard is still an early design that has the ES labeling slapped across all corners, including the socket itself (reads prototype & made by LOTES). The LGA 7529 socket will be part of the Intel Mountain Stream platform which is designed for the next-gen Granite Rapids and Sierra Forest chips.
The leaker of this Intel LGA 7529 socket engineering motherboard anticipates that the upcoming Xeon platform will support P-Core variants with up to 86 and 132 cores, E-Core variants with up to 334 and 512 cores, as well as HBM variants.
The motherboard will be fully compliant with the PCIe Gen 5.0 interface, featuring at least 96 Gen 5 lanes. The memory layout will include support for 12-channel DDR5-6400 memory at the start with Granite Rapids chips. These 12 channels would allow for up to 24 RDIMM slots for an insane DRAM capacity.
The Intel Ultra Path Interconnect (UPI) and bandwidth have also been enhanced for the LGA 7529 socket motherboards. The PCB connection is also expected to be far superior to competitor AMD. The motherboard lacks a southbridge chip section for using hard drive controllers, input and output controllers, and integrated hardware.
It should be noted that the LGA 7529 socket for the new CPU is much larger than the LGA 4189 socket, but both do share the same pin density. The socket is so big that it can literally house at least five Intel 13th Gen Desktop CPUs or six AMD Ryzen 7000 CPUs.
The PCIe 5.0 Mini Cool Edge IO (MCIO) connector will support a link width of x16 and will be used for the UPI, additional PCIE, GENZ, and CEM connections. The R2214914 VRMs will power the processor and memory with 105A, but the DrMOS is unknown. The platform is designed to easily handle the first-gen chips rated between 400-500W.
The new Sierra Forest Xeon CPUs are rumored to deliver power and performance to support high-density, ultra-efficient computing for the cloud. The Sierra Forest Xeon chips will house at least 344 cores packed within 4 Compute Tiles, each packing 86 cores. If the rumors are correct, there will also be a larger core count version with 528 cores, offering up to 132 cores per tile. It is anticipated that 512 cores would be a more realistic core count, with one cluster being disabled.
The continued expectation for Intel from users is that the company will attempt to outperform AMD's current and future EPYC platforms. Sierra Forest is anticipated to compete with AMD's Bergamo processors that offer 128 Zen 4C cores, and Falcon Shores will go head-to-head with the custom Instinct APU accelerators. The Instinct APU accelerators will introduce the upcoming MI300 accelerator that will launch later in the year. Intel's Sierra Forest processors are expected to launch in 2024, utilizing the Intel 3 (3nm) process node.
