Intel Xeon Range Explained

To simplify such a vast array of CPUs, Intel has divided its offering into three main ranges, Xeon 6 (high-end), Xeon Scalable (mid-range) and Xeon E (entry-level).

It is worth mentioning that there is also a range of Intel CPUs designed for high-end workstations, called Intel Xeon W - you can learn more about these by reading our Intel Desktop CPU Buyers Guide.

Intel Xeon 6 P Processors

Architecture: Granite Rapids

Socket: Intel LGA7529

Previous Generation: Intel Xeon Scalable 5th gen

Intel Xeon 6 P processors feature P-cores and are optimised for a wide range of workloads, including AI inference, machine learning, public cloud workloads and HPC. Xeon 6 P CPUs are available in four main ranges, - 6900 for high-end, 6700 and 6500 for mid-range and 6300 for the entry-level.

They also retain the dedicated QuickAssist Technology (QAT), Data Streaming Accelerator (DSA), In-Memory Analytics Accelerator (IAA) and Dynamic Load Balancer (DLB) cores seen in the Xeon 6 E range. Intel Xeon 6 P CPUs also feature improved memory throughput with the fastest DDR5 memory available, MRDIMM. These can deliver more than 37% greater memory bandwidth than RDIMMs.

Intel Xeon 6 E Processors

Architecture: Sierra Forest

Socket: Intel LGA4710-2

Previous Generation: Intel Xeon Scalable 5th gen

Intel Xeon 6 E processors with E-cores are optimised for high core density and exceptional performance per watt, delivering distinct advantages for cloud-scale workloads that demand high task-parallel throughput. In comparison to Intel Xeon Scalable 2nd gen CPUs, which make up the majority of systems within today's datacentres, Xeon 6 E processors with E-cores can deliver more than 2.6x better results. This efficient performance is also ideal where power, space, and cooling are limited.

They also retain the dedicated QuickAssist Technology (QAT), Data Streaming Accelerator (DSA), In-Memory Analytics Accelerator (IAA) and Dynamic Load Balancer (DLB) cores seen in the Xeon 6 P range.

Intel 5th Gen Xeon Scalable Platform

Architecture: Emerald Rapids

Chipset: Intel C740-series

Previous Generation: Intel Xeon Scalable 4th gen

Intel 5th gen Xeon Scalable processors build on the foundation created by the 4th gen CPUs. Memory capacity remains the same but bandwidth has been increased and there is still support for eight-channels of DDR5 memory and 80 lanes of PCIe 5.0. The maximum number of cores has been increased from 60 to 64.

They also retain the dedicated QuickAssist Technology (QAT), Data Streaming Accelerator (DSA), In-Memory Analytics Accelerator (IAA) and Dynamic Load Balancer (DLB) cores seen in the 4th gen Xeon Scalable range.

Advanced Features

Intel Xeon processors include advanced features for workload acceleration and security.

Workload Accelerators

Intel 4th gen Xeon Scalable and later processors have dedicated accelerators for speeding-up specific operations, freeing up the CPU cores for other tasks. Not every accelerator is present on every CPU, so check the specs carefully if a particular accelerator is important for you.

AMX - Advanced Matrix Extensions

Accelerates deep learning and AI model training. AMX works by speeding up matrix-multiply tasks by up to 8x versus older VNNI instructions, boosting performance in tasks such as recommendation engines, natural language processing, and image recognition.

IAA - In-memory Analytics Accelerator

A purpose-built accelerator that offloads from the CPU cores the compression and decompression of very high throughput in-memory databases. For example, in RocksDB IAA delivers 2x the operations per second versus traditional CPU cores.

DSA - Data Streaming Accelerator

A purpose-built accelerator that offloads from the CPU cores common data movement tasks between core components such as CPU and system memory as well as storage and network devices. For storage applications, DSA can improved I/O by up to 1.7x.

DLB - Dynamic Load Balancer

A purpose-built accelerator that offloads from the CPU cores responsibility for allocating the distribution of network processing, dynamically allocating these tasks across the CPU as the load varies.

QAT - QuickAssist Technology

A purpose-built accelerator that offloads from the CPU cores encryption and decryption tasks such as cryptography, key protection and data compression. This leaves the CPU cores free to serve a larger number of clients.

Intel Xeon CPU Security

Security with server workloads is important for both the user experience and customer satisfaction. To protect data in use, the latest Intel Xeon processors use Intel Confidential Computing technology.

Trust Authority

Intel Trust Authority is a suite of trust and security services that provides customers with assurance that their apps and data are protected on the platform of their choice, including multiple cloud, edge, and on-premises environments. Intel Trust Authority takes Confidential Computing to the next level with a Zero Trust attestation SaaS that verifies the trustworthiness of compute assets.

Trust Domain Extensions

Intel Trust Domain Extensions (TDX) is a hardware-based trusted execution environment that facilitates the deployment of trust domains which are hardware-isolated virtual machines (VM) designed to protect sensitive data and applications from unauthorised access. Intel TDX ensures data integrity, confidentiality, and authenticity.

Software Guard Extensions

Intel Software Guard Extensions (SGX) helps protect data in use via unique application isolation technology. By protecting selected code and data from modification, developers can partition their application into hardened enclaves or trusted execution modules to help increase application security.

Intel Xeon E CPUs is a range of CPUs designed for entry-level and small business server workloads at an attractive price point.

The first Intel Xeon processor was introduced in 1998, since then Intel has launched multiple generations of faster, more powerful Xeon CPUs.

Intel Xeon 6 is a range of server CPUs. Intel Xeon 6 P CPUs deliver maximum performance for AI and HPC workloads via high-frequency cores, while Xeon 6 E CPUs deliver maximum core density for virtualised workloads with lots of energy-efficient cores.

Intel Xeon Scalable is a range of server CPUs. Intel Xeon Scalable CPUs deliver competitive performance for a wide range of workloads at a reduced price point compared to Xeon 6.

SMP (Symmetrical Multi Processing) is when a server has more than one physical CPU, typically two, but up to as many as eight CPUs. Each CPU in the server has to the same make and model, with software operating across all CPUs equally.

ECC (Error Correction Code) memory allows the system to recreate the correct data in real time in case of an error, using a form of parity, which is a method of using a single bit of data to detect errors in larger groups of data. ECC memory looks different to non-ECC memory as it has an extra chip that performs the ECC calculations.

TDP (Thermal Design Power) is a measure of how much electrical power a CPU consumes at maximum load. A higher TDP usually indicates higher performance and means the CPU will require a more capable cooling system.
