Celeron is a brand name given by Intel to a large number of different x86 microprocessor models that they produced and marketed as a budget/value CPU line. The Celeron family complements Intel's higher-performance (and more expensive) Pentium CPU family. Introduced in April 1998, the first Celeron was based on the Pentium II core. Later versions were based on the Pentium III, Pentium 4, and Pentium M. These processors are suitable for most applications, but their performance is somewhat limited when it comes to running intense applications, such as cutting edge games or graphical modeling programs, as compared to that of their high-end counterparts.
