About Intel® Processor Numbers

Intel® processors

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® processor E3, E5, and E7 families and Intel® Xeon Phi™ product family

The latest Intel® Xeon® processor numbering system is an alpha numeric representation of product line, product family, and version. An "L" suffix will be used to identify a low power processor. The version number will not be used in the first processor generation.

Processor name = brand (Intel® Xeon Phi™ processor) + performance shelf (5) + gen indicator (1) + SKU numberic digits (10) + product line suffix (P)
Processor name = brand (Intel® Xeon Phi™ processor) + performance shelf (7) + gen indicator (1) + SKU numberic digits (10) + product line suffix (P)
