Intel Xeon Scalable 5th gen

Previous generation

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 three main ranges, with a one-digit number signifying the range, i.e. 9 for high-end, 7 for mid-range and 5 for entry-level. Xeon 6 P retains the dedicated cores introduced in Xeon Scalable 4th gen CPUs which speed up specific tasks - QuickAssist Technology (QAT), Data Streaming Accelerator (DSA), In-Memory Analytics Accelerator (IAA) and Dynamic Load Balancer (DLB). 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 Scalable 5th gen

Previous generation

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 Xeon Scalable 4th gen

Previous generation

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. As with the 4th gen Xeon range, 5th gen CPUs feature dedicated accelerators cores for specific workloads including Intel AMX - Advanced Matrix Extensions; Intel IAA - In-memory Analytics Accelerator; Intel DSA - Data Streaming Accelerator; Intel DLB - Dynamic Load Balancer; and Intel QAT - QuickAssist Technology.

Intel Xeon Accelerators

As already mentioned select Intel Xeon processors include dedicated accelerators for accelerating specific operations, freeing up the CPU cores for other tasks.

AMX

AMX

Intel 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, image recognition, object detection and media analytics.

IAA

IAA

Intel IAA, In-memory Analytics Accelerator, is 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. Not all CPUs include Intel IAA, please contact us to discuss your requirements.

DSA

DSA

Intel DSA, Data Streaming Accelerator, is 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 and decrease latency by up to 45%. Not all CPUs include Intel DSA, please contact us to discuss your requirements.

DLB

DLB

Intel DLB, Dynamic Load Balancer, is 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. DLB accelerates network tasks such as creating vRANs, secure gateways, packet processing and content delivery networks. Not all CPUs include Intel DLB, please contact us to discuss your requirements.

QAT

QAT

Intel QAT, QuickAssist Technology, is 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. Not all CPUs include Intel QAT, please contact us to discuss your requirements.

Intel Xeon CPU Security

Security with server workloads is important for both the user experience and customer satisfaction. IT teams must protect against a growing number of security threats and remain compliant with privacy regulations, whether on-premises or in the cloud. To protect data in use, the latest Intel Xeon processors use Intel Confidential Computing technology to allow you to pick the confidential computing technologies that best meet your business and regulatory requirements. Explore the tabs to learn more.

Trust Authority

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 at the network, edge, and in the cloud. Intel Trust Authority attests to the validity of Intel Confidential Computing environments, also known as Trusted Execution Environments (TEEs).

Trust Domain Extensions

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. This software module runs in a new CPU Secure Arbitration Mode (SEAM) as a peer virtual machine manager (VMM), and supports trust domain entry and exit using the existing virtualisation infrastructure. Intel TDX ensures data integrity, confidentiality, and authenticity, which empowers engineers and tech professionals to create and maintain secure systems, enhancing trust in virtualised environments.

Software Guard Extensions

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 SGX protects data actively being used in the processor and memory by creating a trusted execution environment called an enclave. Users can scale the amount of trusted code inside an enclave from an entire application with thousands of lines of code to a single function with just few dozen, minimising the attack surface and access to sensitive data.
