  • Significant 40% speed boost over predecessor
  • Increased core counts and cache sizes
  • Specialized accelerators for improved performance in specific areas


Intel is gearing up to release its 5th Gen Xeon Emerald Rapids processors on December 14th, and the chipmaker claims that these new processors will offer a significant 40% speed boost over their predecessor, Sapphire Rapids. While Emerald Rapids is considered a soft refresh of Sapphire Rapids, it brings some notable improvements to the table.

One of the key upgrades in Emerald Rapids is the increase in core counts and cache. These processors will offer up to 64 cores and 480 MB of L3 cache, surpassing the corresponding AMD EPYC parts. Additionally, the L2 cache adds up to 128MB, resulting in a total cache size of 608 MB. Each chiplet in Emerald Rapids consists of 35 cores, with three disabled, along with dual memory controllers supporting DDR5-5600MT/s DIMMs and three PCIe controllers.

Intel claims that Emerald Rapids will deliver a generational uplift of 20-30% in data center workloads, including web, high-performance computing (HPC), and media tasks. To further enhance performance in specific areas, Intel has included specialized accelerators in these processors. These accelerators boost AI (AMX), network (QAT), streaming (DSA), and database (IAA) throughputs by up to 70% compared to the previous Sapphire Rapids products.

The 5th Gen Xeon family from Intel will be divided into four stacks: P-core and E-core segments, further divided into SP (Scalable Performance) and AP (Advanced Performance) tiers. The P-core lineup will utilize the Raptor Cove core architecture, while the E-core variants will leverage Sierra Glenn, a Crestmont variant optimized for cloud workloads. The SP and AP stacks will differ in terms of core counts, cache sizes, and IO capabilities, with the former targeting the lower-end market and the latter catering to the higher-end segments.

Overall, Intel’s 5th Gen Xeon Emerald Rapids processors promise significant performance improvements over their predecessors. With higher core counts, increased cache sizes, and specialized accelerators, these processors are poised to deliver enhanced performance in various data center workloads. As the launch date approaches, it will be interesting to see how these processors fare in real-world scenarios and how they stack up against the competition.
