cpu - Meaning of Intel processor suffixes

I just bought a Core i7 second generation machine which shows the processor in the BIOS as:

Intel Core i7-2620M CPU @ 2.70Ghz

I have seen i7 3rd and 4th generation processors on Google but I don't understand the suffix (i.e. what is meant by M). I have also seen other processors with suffixes like MQ* and **QX.

What do these suffixes mean?

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.
