What Intel’s 2023‑2025 Xeon Roadmap Reveals for Data Center CPUs

Intel Xeon Roadmap 2023‑2025 Overview

Intel recently announced its Xeon processor roadmap covering 2023 to 2025. The plan introduces a series of P‑core and E‑core CPUs—Emerald Rapids, Granite Rapids, Sierra Forest, and Clearwater Forest—targeted at high‑performance computing (HPC), artificial intelligence (AI), and data‑center workloads.

2023: Emerald Rapids (5th‑Gen Xeon)

Emerald Rapids is scheduled for a Q4 2023 launch and is built on the Intel 7 process. It aims to deliver higher performance and energy efficiency for HPC, AI, and data‑center applications. Key highlights include:

Use of the Reaptor Cove core, an optimized version of Golden Cove, offering a 5‑10% IPC improvement.

Maximum configuration of 64 cores and 128 threads.

Up to 320 MB L3 cache (448 MB total cache with 128 MB L2), a 2.84× increase over Sapphire Rapids‑8490H.

Compatibility with the existing 4th‑gen Eagle Stream platform for easy migration.

Cache comparison (L3 + L2):

Intel Emerald Rapids‑SP (64‑core SKU): 320 MB L3 + 128 MB L2 = 448 MB total.

AMD EPYC Genoa (64‑core SKU): 384 MB L3 + 96 MB L2 = 480 MB total.

Intel Sapphire Rapids‑SP (60‑core SKU): 112.5 MB L3 + 120 MB L2 = 232.5 MB total.

2024: Granite Rapids and Sierra Forest

In 2024 Intel will release Granite Rapids and the first E‑core Xeon, Sierra Forest, both on the newer Intel 3 process with Redwood Cove cores.

Granite Rapids‑SP will increase core density, memory, and I/O capabilities, supporting DDR5‑8800 MCR memory (83% peak bandwidth) and up to 1.5 TB/s platform bandwidth. A demo showed DDR5‑8000 MT/s on a dual‑socket platform.

Sierra Forest will be the inaugural E‑core Xeon, featuring up to 144 Intel‑3 cores, optimized for cloud‑native workloads, and positioned against AMD’s EPYC Bergamo 128‑core CPUs.

2025: Clearwater Forest

Clearwater Forest will replace the current lineup as the second‑generation E‑core Xeon family. It will be manufactured on Intel’s 18A process, leveraging the RibbonFET architecture for a significant leap in transistor density and chip performance.

Additional Roadmap Highlights

Intel also updated its future GPU, dedicated AI accelerator, and FPGA plans. New GPU products include the Melville Sound data‑center GPU Flex series and the Falcon Shores accelerator, which will evolve from a GPU‑only design to a heterogeneous CPU‑GPU solution similar to AMD’s Instinct MI300. The roadmap mentions next‑generation Habana Gaudi AI accelerators, as well as upcoming eASIC and AGILEX FPGA families.

Conclusion

Intel’s multi‑year Xeon roadmap demonstrates a strong commitment to continuous innovation, aiming to keep the company competitive in HPC, AI, and data‑center markets by delivering higher performance, better energy efficiency, and greater scalability across a wide range of applications.
