Shulou(Shulou.com)11/24 Report--

Thanks to CTOnews.com netizens Wu Yanzu and OC_Formula for the clue delivery! CTOnews.com March 30 news, Intel today announced the 2023-2025 Xeon strong CPU roadmap, and a brief introduction of the subsequent product data.

Intel announced that it would divide the Xeon series into P-Core, the previous Xeon series, and E-Core, a newly added energy-efficient architecture that will provide better power efficiency.

CTOnews.com Summary 2023-2025 Xeon strong CPU roadmap includes:

Emerald Rapids (P-Core) at the end of 2023

Sierra Forest (E-Core) in the first half of 2024 and Granite Rapids (P-Core) released later

Clearwater Forest (E-Core) in 2025.

2023 P-Core products Intel 4th generation Sapphire Rapids CPU series follow-up product-5th generation Xeon series code name Emerald Rapids. Emerald Rapids-SP CPU, which is still the traditional P-Core series, has begun to provide samples and is scheduled for delivery in the fourth quarter of 2023.

The Emerald Rapids-SP series of improvements include improved energy efficiency and higher core density. Generation 5 Emerald Rapids will be fully compatible with existing generation 4 Eagle Stream platforms and can be easily migrated from previous generation platforms.

Emerald Rapids is expected to use the Raptor Cove core architecture, an improved version of the Golden Cove core that will provide 5-10% IPC improvements over the Golden Cove core. It will also contain up to 64 cores and 128 threads, a slight improvement over the 56 cores and 112 threads of the previous generation of Sapphire Rapids chips.

According to the picture released by the whistleblower @ SkyJuice, the 5th generation XCC exposure of the most powerful Emerald Rapids will include two die based on the Intel 7 process, each about 770mm ².

The 2024 P-Core product 2024 Granite Rapids-SP CPU will adopt the latest x86 CPU architecture based on the Intel 3 process, which is expected to be called the Redwood Cove core, and may have more than 100 cores.

Granite Rapids-SP Xeon processors will support Mountain Stream and Birch Stream platforms, further increasing core density, memory, and I / O, such as support for DDR5-8800 MCR RDIMM. The new memory will increase peak bandwidth by 83% and provide up to 1.5 TB / s of bandwidth for the platform. Intel also showed a demonstration of an early Granite Rapids-SP chip that ran DDR5-8000 MT / s memory on a two-socket platform (2S), and the results showed that it worked well:

The new E-Core product, the first generation of Intel Xeon E-Core series, Sierra Forest, is scheduled to be delivered in the 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.

Intel Sierra Forest CPU with 144 cores is expected to compete with AMD's EPYC Bergamo 128-core CPU. Intel showed a demonstration of Sierra Forest CPU, which runs at 100% health on all 144cores, as follows:

Finally, Intel is looking forward to a second-generation E-Core Xeon processor called Clearwater Forest, which is scheduled to be launched in 2025 and will use Intel 18A process nodes to provide more cores. Intel 18A process nodes will improve the RibbonFET architecture, claiming to be able to achieve another major leap in transistor and chip performance.
