November 18, 2023 by our News Team

Intel's upcoming 5th Gen Xeon processors, codenamed Emerald Rapids, offer significant improvements in performance, particularly in AI and HPC workloads, with increased core counts, larger cache sizes, improved memory and PCIe support, and workload-specific optimizations.

  • Up to 448MB of L3 cache, three times more than their predecessors
  • Up to 1.4 times faster performance than the Sapphire Rapids flagship in AI and HPC workloads
  • Support DDR5-5600 memory, providing faster data access and improved overall system performance


Intel has recently revealed details about its upcoming 5th Gen Xeon processors, codenamed Emerald Rapids. These CPUs, which are architecturally similar to Sapphire Rapids, offer significant improvements in performance, particularly in the areas of AI and HPC workloads.

One of the standout features of the Emerald Rapids processors is the increase in core count and cache size. These new Xeon Scalable chips will provide up to 448MB of L3 cache, three times more than their predecessors. Additionally, the core counts have been increased by four on the flagship model, surpassing the capabilities of Sapphire Rapids.

The performance gains of Emerald Rapids are particularly notable in AI and HPC workloads. Intel has focused on enhancing these areas by substituting AI tasks with Speech Recognition and HPC with LAMMPS. The next-gen Xeon processors are expected to deliver up to 1.4 times faster performance than the Sapphire Rapids flagship in these specific workloads. Media transcoding will also see a significant improvement, with a 20% generational uplift.

Apart from the core and cache enhancements, Emerald Rapids also brings upgrades to memory support and PCIe lane count. The processors will support DDR5-5600 memory, providing faster data access and improved overall system performance. Additionally, the Gen 5 PCIe lane count has been increased to 80, allowing for faster data transfer rates and better connectivity options.

Physically, Emerald Rapids differs from Sapphire Rapids in terms of chiplet configuration. While Sapphire Rapids features multiple chiplets, Emerald Rapids utilizes only two denser chiplets. This design choice allows for more space to be allocated to SRAM, further enhancing performance. Both processors leverage the same 7nm-class process technology but incorporate workload-specific optimizations to improve overall efficiency.

Intel’s Xeon Emerald Rapids processors are set to deliver a significant boost in AI performance and HPC capabilities compared to their predecessors. With increased core counts, larger cache sizes, and improved memory and PCIe support, these processors are poised to meet the demands of modern computing workloads. As Intel continues to push the boundaries of processor technology, the Emerald Rapids CPUs are a promising addition to their lineup.
