Introduction

Since its launch, in April, 1998, Intel Celeron processor has been going through some changes. The name Celeron is used by Intel to denominate its low cost line of processors. In fact, Celeron is an economic version of Intel top processors. In other words, Celeron is a simplified version of Pentium II, Pentium III, Pentium 4 or Core 2 Duo, with some of its features being reduced or removed. Celeron models already launched and top processors in which they are based on are listed below:

Celeron distinguishes itself from Pentium II, Pentium III, Pentium 4 or Core 2 Duo basically in three aspects:

  • L2 memory cache size
  • Internal clock
  • External bus clock

Because of these differences Celeron is cheaper and of low-performance, compared to the Pentium II, Pentium III, Pentium 4 and Core 2 Duo processors, thus it fits well to domestic users market or to those who don’t need great power in the computer.
