Emerald Rapids is the codename for Intel's fifth generation Xeon Scalable server processors based on the Intel 7 node. Emerald Rapids CPUs are designed for data centers; the roughly contemporary Raptor Lake is intended for desktop and mobile usage. Nevine Nassif is a chief engineer for this generation.
Features
CPU
- Up to 64 Raptor Cove CPU cores per package
- Up to 32 cores per tile, reducing the max tiles to two
- 5 MB of L3 cache per core (up from 1.875 MB in Sapphire Rapids)
- Speed Select Technology that supports high and low priority cores

List of Emerald Rapids processors
Emerald Rapids-SP (Scalable Performance)
CPUs in italic are actually Sapphire Rapids processors, and they still have 1.875 MB of L3 cache per core.
Suffixes to denote:
- +: Includes 1 of each of the four accelerators: DSA, IAA, QAT, DLB
- H: Database and analytics workloads, supports 4S (Xeon Gold) and/or 8S (Xeon Platinum) configurations and includes all of the accelerators
- M: Media transcode workloads
- N: Network/5G/Edge workloads (High TPT/Low Latency), some are uniprocessor
- P: Cloud and infrastructure as a service (IaaS) workloads
- Q: Liquid cooling
- S: Storage & Hyper-converged infrastructure (HCI) workloads
- T: Long-life use/High thermal case
- U: Uniprocessor (some workload-specific SKUs may also be uniprocessor)
- V: Optimized for cloud and software as a service (SaaS) workloads, some are uniprocessor
- Y: Speed Select Technology-Performance Profile (SST-PP) enabled (some workload-specific SKUs may also support SST-PP)
- Y+: Speed Select Technology-Performance Profile (SST-PP) enabled and includes 1 of each of the accelerators.
