Intel Unveils 2023-2025 Xeon CPU Roadmap: Emerald Rapids In 2023, Granite Rapids & Sierra Forest In 2024, Clearwater Forest In 2025
Intel has just unveiled its next-generation Xeon Data Center CPU roadmap for 2023-2025 featuring brand new P-Core & E-Core chip families.
Intel has segmented its next-gen Xeon Data Center CPU lineup into two categories, P-Core & E-Core. The P-Core products will be the standard Xeon products that we have seen over the years. Then we have the E-Core products which will utilize the more energy-efficient architectures & the first product is expected next year in the form of Sierra Forest.
The follow-up to Intel's 4th Gen Sapphire Rapids CPU lineup comes in the form of the 5th Gen Xeon family, codenamed Emerald Rapids. The Emerald Rapids-SP CPUs are already sampling and are on schedule to deliver in Q4 2023.
These chips will offer higher-quality silicon with volume validation in progress. Other features of the Emerald Rapids-SP lineup include a focus on higher performance/watt in the same power envelope, delivering increased core density gen-on-gen. The chips will be fully compatible with the existing 4th Gen Eagle Stream platform, allowing for easy migration from the previous generation.
Emerald Rapids is expected to make use of the Raptor Cove core architecture which is an optimized variant of the Golden Cove core that will deliver 5-10% IPC improvement over Golden Cove cores. It will also pack up to 64 cores & 128 threads which is a small core bump over the 56 cores & 112 threads featured on Sapphire Rapids chips.
Emerald Rapids-SP Xeon CPUs will be peaking out at 64 cores and available in 1S/2S server configurations. The 4S-8S platforms will have to wait till the next-generation Granite Rapids-SP Xeon chips for an upgrade. But with that said, one key area that is expected to see a huge boost on Emerald Rapids-SP Xeon CPUs is
