Intel’s Next-Gen LGA 7529 Xeon Platform to Deliver 500W per CPU, 12-Channel DDR5
Supporting ‘Granite Rapids’ and ‘Sierra Forest’ processors, Intel’s next-generation data center platforms offer significant improvements in terms of memory bandwidth and input/output capabilities.according to the slide It was published by a well-known hardware leaker Yuki_AnSHowever, the increased performance and throughput comes at a price. The next generation Xeon processors will have a thermal design power of up to 500W.
Intel’s 6th Generation Xeon Scalable ‘Granite Rapids’ processors increase the high-performance core count compared to Sapphire Rapids and Emerald Rapids CPUs, but with energy-efficient cores designed for high-density cloud data centers. Based on Intel’s Xeon “Sierra Forest” processors, even higher core counts. These processors use Intel’s LGA7529 socket and feature a TDP of up to 500W. As such, peak power consumption at high load is expected to be significantly higher than previous generation parts.
To power these cores, new CPUs require a very sophisticated memory subsystem. In fact, the new CPU features 12 DDR5 memory channels that support both traditional DDR5-6400 memory modules (one DIMM per channel) and DDR5-8000 MCR DIMMs. When all channels are fully utilized, such a memory subsystem offers up to 614.4 GB/s – 768 GB/s of bandwidth, a significant increase from Sapphire Rapids’ 307.2 GB/s.
Intel’s new data center processors also feature up to 96 PCIe Gen5 lanes with the CXL protocol for high-performance accelerators/coprocessors, storage devices, memory expanders, and other devices that use PCIe. The CPUs also support 6×24 UPI links for inter-CPU communication.
One of the platforms Intel is preparing for its Granite Rapids and Sierra Forest processors is called ‘Avenue City RP’. In addition to the main features of the CPU, this motherboard supports PFR 4.0 root of trust, the new generation of his RunBMC AST26000 module and OCP 3.0 network card.
The slides look like Intel slides and are dated 2023.
