IT Home News On March 30th, today, Intel announced Xeon Xeon Processor Roadmap for 2023-2025 and briefly provided further product data.
Intel has announced that it will split Xeon series into two series: P-Core and E-Core. The former is previous Xeon series, while latter is a newly added power-saving architecture that delivers higher power efficiency.
IT Home Brief, Xeon Xeon Processor Roadmap 2023-2025 includes:
Emerald Rapids (P-Core) by end of 2023;
Sierra Forest (E-Core) in first half of 2024 and Granite Rapids (P-Core) will be released later;
Clearwater Forest (E-Core) in 2025.
The successor to 4th Gen Intel Sapphire Rapids CPU family is 5th Gen Xeon family codenamed Emerald Rapids. The Emerald Rapids-SP processors remain traditional P-Core series and are currently in sampling phase and scheduled for delivery in fourth quarter of 2023.
Enhancements to Emerald Rapids-SP series, including improved energy efficiency resulting in higher core density. The 5th Generation Emerald Rapids will be fully compatible with existing 4th Generation Eagle Stream platform, making it easy to upgrade from previous generation platform.
Emerald Rapids is expected to use Raptor Cove core architecture, an improved version of Golden Cove core that will provide a 5-10% IPC improvement over Golden Cove core. It will also feature up to 64 cores and 128 threads, which is slightly more than previous generation Sapphire Rapids chip with 56 cores and 112 threads.
According to an image posted by leaker @SkyJuice, 5th generation XCC Xeon Emerald Rapids display will include two dies based on Intel 7 process, each measuring approximately 770mm².
The Granite Rapids-SP CPU in 2024 will use latest x86 CPU architecture based on Intel 3 process, which is expected to be called Redwood Cove core and could have over 100 cores.
Granite Rapids-SP Xeon processors will support the Mountain Stream and Birch Stream platforms, further enhancing core density, memory, and I/O, such as support for MCR RDIMM DDR5-8800 memory modules. The new memory will deliver 83% of peak bandwidth and provide platforms with up to 1.5 TB/s of bandwidth. Intel also showed a demo of an early Granite Rapids-SP chip with DDR5-8000 MT/s memory on a dual-socket (2S) platform, and it worked great:
Sierra Forest, first generation of Intel Xeon E-Core processors, will be available in first half of 2024. The CPU will contain up to 144 cores based on the Intel 3 process and will be built for cloud-optimized workloads.
The 144-core Intel Sierra Forest processor is expected to compete with 128-core AMD EPYC Bergamo processor. Intel showed a demo of Sierra Forest processor running at 100% on all 144 cores, as follows:
Finally, Intel has scheduled release of second generation E-Core Xeon processor called Clearwater Forest, which is scheduled to launch in 2025. It will use Intel 18A Technology Node, providing more cores. The Intel 18A Technology Node will improve on RibbonFET architecture, which is said to provide another significant leap in transistor and chip performance.
