“This is an exciting time for Intel and the Xeon roadmap,” said Lisa Spellman, general manager of Xeon and Intel vice president. , with the fifth-generation Xeon (codenamed Emerald Rapids) launching in the fourth quarter of 2023, our 2024 data product portfolio will power the industry.'

The roadmap shown in the material announced in March 2023 looks like this. Emerald Rapids processors will be released in Q4 2023, Sierra Forest processors in 2024, Granite Rapids processors in 2024, and Clearwater Forest processors in 2025.



・5th generation Xeon scalable processor 'Emerald Rapids'
Scalable Xeon processors for data centers are 4th generation Sapphire Rapids featuring 4800MT transfers per second DDR5 DRAM and 80 lanes of PCIe 5.0/CXL 1.1 connectivity. The new 5th Gen Emerald Rapids will move to a 12 channel configuration supporting DDR5 and MCR DRAM DIMMs as well as 136 lanes of PCIe 5.0/CXL 2.0 connectivity.

Emerald Rapids has been available in samples since March 2023 and will be released in Q4 2023.



MCR DIMM can expect a significant improvement in bandwidth compared to DDR5 DRAM, and Intel's

Ronark Singhal Fellow said, ``With the transition from Sapphire Rapids to Emerald Rapids, memory bandwidth will improve by less than three times. I would.”

・Xeon processor with P core 'Granite Rapids'
Xeon processors with P-cores are optimized for the lowest total cost of ownership (TCO) for high-core performance-intensive and general-purpose computing workloads. Xeon has achieved better AI performance than other CPUs, but Granite Rapids will further enhance AI performance. Built-in accelerators further power targeted workloads for greater performance and efficiency.

・Xeon processor with E core 'Sierra Forest'
Xeon processors with E-cores offer best-in-class performance density, greatly benefiting cloud-native and hyperscale workloads.

Sierra Forest offers 2.5x higher rack density and 2.4x better performance per watt than its predecessor. It supports 1S and 2S servers with CPU up to 144 cores and a low TDP of 200W.

Processors with P cores are aimed at performance optimization, and processors with E cores are aimed at efficiency optimization.



Sierra Forest is slated for 2024, followed by Granite Rapids later that year.
