I found this quite useful as a beginner to understanding lntel's suffix definitions for their processors. It's also updated per new generation of Intel Core chips.

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.

10th Generation Intel® Core™ Processor​

Processor numbers in this category use an alphanumeric scheme based on generation and product line details following the brand and its modifier. The first two digits in the five-number sequence indicates the generation (10th) of processor, the next three digits are SKU numbers followed by either U or Y, which represents a category of mobile system the processor is ideally suited for.

The two digits in the four-number sequence indicates the generation (10th) of processor, the next two digits are SKU numbers followed by the level of graphics.

9th Generation Intel® Core™ Processor​


Post edit: Removed older generations.
