Intel’s next-generation datacenter platform, supporting ‘Granite Rapids’ and ‘Sierra Forest’ processors will supply huge enhancements by way of reminiscence bandwidth and enter/output capabilities. That is in response to a slide printed by well-known {hardware} leaker YuuKi_AnS. However elevated efficiency and throughput will come at a worth: next-generation Xeon processors may have a thermal design energy of as much as 500W.
Intel’s sixth Technology Xeon Scalable ‘Granite Rapids’ processors will improve high-performance core depend in comparison with Sapphire Rapids and Emerald Rapids CPUs, whereas Intel’s Xeon ‘Sierra Forest’ processors primarily based on energy-efficient cores designed for high-density cloud datacenters will characteristic a fair greater core depend. These processors will use Intel’s LGA7529 socket, and may have a TDP of as much as 500W. So count on their peak energy consumption beneath excessive hundreds to be considerably greater than previous-gen components.
To feed these cores, the brand new CPUs will want a really subtle reminiscence subsystem, and certainly the brand new CPUs will characteristic 12 DDR5 reminiscence channels supporting each typical DDR5-6400 reminiscence modules (one DIMM per channel) in addition to DDR5-8000 MCR DIMMs. When all channels are totally used, such a reminiscence subsystem will present as much as 614.4 GB/s – 768 GB/s of bandwidth, a major improve from Sapphire Rapids’s 307.2 GB/s.
The brand new datacenter processors from Intel can even sport as much as 96 PCIe Gen5 lanes, with the CXL protocol on high for high-performance accelerators/co-processors, storage gadgets, reminiscence expanders, and different gadgets that use PCIe. Additionally, the CPUs will help 6×24 UPI hyperlinks for CPU-to-CPU communications.
One of many platforms that Intel is prepping for its Granite Rapids and Sierra Forest processors is named ‘Avenue Metropolis RP.’ The motherboard will help key capabilities of the CPUs, in addition to PFR 4.0 root of belief, a new-generation RunBMC AST26000 module, and OCP 3.0 community playing cards.
The slides do appear to be Intel’s slides and are dated 2023. However since they arrive from an unofficial supply, their contents ought to after all be taken with a grain of salt whatever the leaker’s observe report.
