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.

Server and Workstation Processors
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.
| SKU Level | |
|---|---|
| 8 | Platinum |
| 6, 5 | Gold |
| 4 | Silver |
| 3 | Bronze |
| Processor Generation | |
| 1 | 1st Gen Intel® Xeon® Scalable processors |
| Integrations and Optimizations | |
| F | Fabric |
| T | High Tcase/extended reliability |
| Memory Capacity | |
| No suffix | 768 GB per socket |
| M | 1.5 TB per socket |
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. Where applicable, an alpha suffix appears at the end of the processor name, which represents the processor line. The version number will not be used in the first processor generation.
