Intel Xeon Processors and Scalability

Scalable processors take advantage of the server motherboards that feature multiple sockets for CPU installation. Servers typically have 2, 4, 8, 16, or 32 CPU sockets for scaling purposes. By installing multiple CPUs on a single motherboard, users can scale the CPU power up and down depending on the workload requirements.

The 4th Gen Intel Xeon Scalable Platinum processors feature advanced 2, 4, and 8-socket support. This versatility makes them the best choice for demanding edge and cloud workloads. The Gold series supports up to four sockets per server for scalable performance.

The Impact of 4th Gen Intel Xeon Scalable Processors

Arguably the most impactful feature of the 4th Gen Intel Xeon Scalable processors is the native integration of accelerators in some CPU models. The built-in acceleration, in many cases, eliminates the need for 3rd party discrete acceleration.

Different Xeon Scalable processor versions can now be used to fine-tune the server setup and tailor it for different workloads. Fields such as AI and machine learning may benefit most from built-in accelerators.

Another important feature of the fourth generation of Xeon processors is Intel on Demand. It allows users to purchase a key to unlock additional built-in accelerators on selected processors depending on the need. The ability to use the processors with inactive accelerators ensures that additional cost is paid only when the specific accelerator is necessary to support the workload.
