Intel Xeon Scalable CPUs

Since its initial release in 2017 Intel has continued to develop new versions of its Xeon Scalable server CPUs. Currently there are three versions available, the latest 5th gen based on Emerald Rapids architecture, the 4th gen based on the Sapphire Rapids architecture and the value-orientated 3rd gen based on the Ice Lake architecture. Click on the tabs below to explore each generation.

Intel 5th Gen Xeon Scalable Platform

Building on the 4th gen CPUs, Intel 5th gen Xeon Scalable processors powered by the Emerald Rapids architecture deliver market leading IT infrastructure. Intel 5th gen Xeon Scalable processors deliver more compute and faster memory at the same TDP as the previous generation. Their software and platform are compatible with the 4th gen, so there is minimal testing and validation when deploying new systems.

Accelerated AI

Intel AMX, Advanced Matrix Extensions, has been enhanced in the 5th gen Xeon CPUs driving up to 2.7x better AI inference performance. Fine-tune deep learning models or train small to medium models in just minutes. Intel AMX delivers discrete accelerator performance without added hardware and complexity and excels in transfer learning and retraining, so you can keep your models current.

Class Leading Security

Intel Trust Domain Extensions (TDX) offers isolation and confidentiality at the virtual machine (VM) level. Within an Intel TDX confidential VM, the guest OS and VM applications are isolated from access by the cloud host, hypervisor, and other VMs on the platform. Intel TDX offers a simpler migration path for existing applications to move to a trusted execution environment (TEE).

Unrivalled Storage Performance

Intel Virtual RAID on CPU (VROC) is an enterprise RAID solution that unleashes the performance of NVMe SSDs, enabled by a feature in Intel Xeon Scalable processors called Intel Volume Management Device (Intel VMD), an integrated controller inside the CPU PCIe root complex. Intel VROC enables these benefits without the complexity, cost, and power consumption of traditional hardware RAID host bus adapter (HBA) cards placed between the drives and the CPU.

Intel 4th gen Xeon Scalable Features and Benefits

The dawn of the accelerated era

Intel 4th gen Xeon CPUs mark a new chapter in the Xeon story, for the first time adding fixed function accelerators which speed up specific tasks, freeing up the main CPU cores for other workloads. These four accelerators, Intel IAA, DSA, DLB and QAT are explored in more detail below. In addition to these new dedicated accelerators the new Sapphire Rapids architecture adds support for 8-channels of 8TB of DDR5 memory and the I/O has been upgraded to 80 lanes of PCIe 5.0, providing double the bandwidth of PCIe 4.0. Finally, switching to a new 7nm manufacturing process enables the core count to be increased from 40 to 60 cores.

AI acceleration

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.

Database acceleration

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.

Accelerated data transfers

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.

Network acceleration

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.

Crypto acceleration

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.

Accelerated HPC

Select 4th gen Xeon processors, known as Xeon Max CPUs, feature an additional 64GB of HBM2e memory. This can be set to act as a giant cache or homogenous memory pool with DRAM, accelerating HPC memory-bound workloads, modelling and simulation, manufacturing, AI and deep learning, energy and earth systems.

Expandable Memory

In addition to the 8TB of DDR5 DRAM and Optane Memory Intel 4th gen Xeon CPUs also support memory and accelerator modules using the CXL 1.1 protocol. CXL (Compute Express Link) is an open standard for CPU to CPU and CPU to memory connections using the same physical slots as PCIe. CXL provides a unified coherent memory space between CPUs and accelerators.

Persistent Memory

In addition to traditional DRAM Intel 4th gen Xeon Scalable CPUs from the Platinum and Gold ranges support PMEM in the form of Intel Optane Memory 300-series DIMMs. Being on the memory bus allows PMEM to have DRAM-like access to data, which means that it has nearly the same speed and latency of DRAM but the non-volatility of NAND flash. PMEM offers numerous advantages such as lower access latencies, support for larger datasets and hardware encryption and when compared to DRAM, PMEM modules come in much larger capacities and are less expensive per gigabyte. Servers can use PMEM modules as ultra-fast, persistent storage to accelerate tasks such as fraud detection, cyber threat analysis and web experience personalisation.
