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.
