Intel Xeon Processors Buyers Guide
What is an Intel Xeon CPU or Processor?
The Central Processing Unit, or the CPU, is one of the most critical components to consider when buying or building a new workstation or server or upgrading an existing one. Intel is undoubtedly the biggest player in this market and in this buyer's guide we'll provide an overview of the key Intel Xeon CPU families with suggestions of which to choose depending on your business needs and workloads – from digital content creation and commercial VR applications through to everyday business continuity tasks and high performance computing (HPC).
It is essential when choosing your Xeon CPU (or CPUs if multiple are required) that you choose a compatible motherboard so we'll indicate this for each processor family as we go through them. As Intel has a regular upgrade cycle for their product range it is vital to know if you are looking at the latest generation, and if you’re considering an upgrade what CPU supersedes your current one, so we’ll cover this too.
Xeon is aimed primarily at business workstations and servers. These CPUs typically offer more cores than mainstream PC CPUs, but the clock speeds don’t necessarily directly compare to their Core i7 and i9 counterparts. Xeon CPUs tend to have a lot more built-in, business-critical technology - for example, they support error-correcting code (ECC) memory, which prevents data corruption and system crashes. For businesses where continuous workloads are mission-critical, even a few hours downtime can cost far more than ECC memory is worth. Also Xeon processors support far more RAM than Core range CPUs do, as well as many more PCI-E lanes for connecting expansion cards. With all these extra features, scalability and fail-safes, naturally, the price reflects this.
The Intel Xeon Range Explained
To help customers pick an Intel processor, its chips are split into unique families targeted at the following types of system.
|Xeon Scalable||Xeon W-3200||Xeon W-2200||Xeon W-1200||Xeon E-2200|
|MULTI-PROCESSOR WORKSTATION OR SERVER||HIGH-END WORKSTATION||HIGH-END WORKSTATION||MID-RANGE WORKSTATION||ENTRY-LEVEL SERVER|
Intel Xeon Scalable Processors
Intel Xeon Scalable processors are now in their 3rd generation and deliver industry leading, workload optimised performance, with built-in AI acceleration to help speed data’s transformative impact. The range is so extensive it is subdivided into three types, each designated a colour, Platinum, Gold, and Silver, but all models can be deployed in at least two processors per system, with some models even supporting more than two CPUs per server. These three families of CPU cover all workstation and server uses from entry-level tasks in small organisations all the way up to HPC clusters. It is fair to say that there is overlap between these families and it is always important to view a processor choice with your current and future workloads in mind.

Intel Xeon Platinum
Intel Xeon Platinum 8300 family of processors are the best-in-class option for secure, agile, hybrid-cloud datacentre workloads. With enhanced hardware-based security up to eight socket processor performance, each CPU provides up to 40 cores and 80 threads, support for up to 6TB memory per socket and 64 lanes of PCIe 4.0 lanes for add-in cards and NVMe SSDs. These processors are built for mission-critical applications such as real-time analytics, machine learning, artificial intelligence and multi-cloud workloads.
Intel Xeon Gold
With support for the higher memory speeds, and enhanced memory capacity, the Xeon Gold 6300 and 5300 families of processors deliver significant improvement in performance, advanced reliability, and hardware-enhanced security. Supporting up to dual-socket configurations, each CPU provides up to 32 cores and 64 threads, support for up to 6TB memory and 64 lanes of PCIe 4.0 lanes for add-in cards and NVMe SSDs. They are optimised for demanding mainstream datacentre, multi-cloud compute, and network and storage workloads.
Intel Xeon Silver
Intel Xeon Silver 4300 family of processors deliver essential performance, improved memory speed, and power efficiency. Supporting up to dual-socket configurations, each CPU provides up to 20 cores and 40 threads, support for up to 6TB memory and 64 lanes of PCIe 4.0 lanes for add-in cards and NVMe SSDs. These processors are ideal for mid-range compute and storage applications.
Intel 3rd gen Xeon Scalable Processors have an 8-channel memory controller that supports a total of 6TB of memory, comprising either traditional DDR4 ECC Registered DIMMs or a mixture of the former plus Intel Persistent Memory DIMMs (formerly known as Optane Memory). For instance, you could configure a system with 4TB of DDR4 memory for maximum performance, or 2TB of DDR4 plus 4TB of Persistent Memory for a maximum capacity of 6TB, which can be optimal for caching and storage when using big datasets.
Special Edition Xeon Scalable Processors
You may see that several of the higher spec CPUs have a letter suffix to denote a special feature regarding that particular model. These are explained below:
H - 4-socket capable processor for high performance computing (HPC) use
U - single-socket only processor
L - processor with large memory support
Y - Speed Select processors that can support three different core counts and corresponding core speeds
N - denotes specific frequencies optimised for networking
V - denotes specific frequencies optimised for virtual machines (VMs)
T - denotes a Long Life Cycle / Thermal reliability - ideal for embedded projects
S - denotes specific frequencies optimised for search applications
B - denotes different die configurations between same numbered processors - these should not be mixed
It is worth checking when choosing a processor with a suffix letter that the power supply of your chosen server is compatible as these processor models often have a higher rated TDP or power consumption.
