About Intel® Processor Numbers

The processor number is one of several factors, along with processor brand, specific system configurations, and system-level benchmarks, to be considered when choosing the right processor for your computing needs.

A higher number within a processor class or family generally indicates more features, but it may be more of one and less of another. Once you decide on a specific processor brand and type, compare processor numbers to verify the processor includes the features you are looking for.

Intel® Xeon® Scalable Processors

Processor numbers for Intel® Xeon® Scalable processors use an alphanumeric scheme based on performance, features, and processor generation following the brand and its modifier. The first digit in the four-number sequence indicated the performance and feature level, the second indicated the processor generation, and the next two are SKU numbers. Where applicable, either one or two alpha suffixes appear at the end of the processor name, which indicate integrations and optimizations and memory capacity.
