The numbers and suffixes of Intel® Xeon® Processors can indicate the performance, features, and generation. See the information below for specific details.

The first digit of the four-number sequence indicates the processor level

Processor Level
8,9	Platinum
6	Gold
5	Gold
4	Silver
3	Bronze

The second digit indicates the processor generation

Processor Generation
1	1st Gen Intel® Xeon®
2	2nd Gen Intel® Xeon®
3	3rd Gen Intel® Xeon®
4	4th Gen Intel® Xeon®
5	5th Gen Intel® Xeon®

The third and fourth digits indicate the SKU number

These numbers do not represent any specific feature. In general, the better processor has a larger SKU number.
