Intel® Core™2 Processors

INTEL Processor models vary according to cache size, clock speed and RAM speed. If you run compute-intensive
programs, the more L2 Cache you have the better. If, however, you use your PC for gaming, streaming video or
watching movies, the size of your L2 Cache is not as significant as having a speedy Front Side Bus and some
juiced up Clock Speed.

A higher number within a processor class or family generally indicates more features, including: cache, clock speed,
Front Side Bus, or other Intel technologies. A higher processor number may also have more of one feature and less
of another.

Processor numbers for the Intel® Core™2 processors family brands are categorized with an alpha prefix followed by
a four digit numerical sequence. The table below explains the alpha prefixes used for the Intel Core 2 processors
families.
