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.

Processor numbers for the 4th Generation Intel® Core™ processors use an alphanumeric scheme based on generation and product line following the brand and its modifier. The first digit in the four-number sequence indicates the generation of processor, and the next three digits are SKU numbers.
