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:

Model	Codename	Based on	Cores	L1 Cache	L2 Cache	Technology	External Bus	Socket
Celeron SEPP	Convington	Pentium II Deschutes core	1	32 KB	-	0.25 µm	66 MHz	Slot 1
Celeron A	Mendocino	Pentium II Deschutes core	1	32 KB	128 KB	0.25 µm	66 MHz	Slot 1
Celeron PPGA	Mendocino	Pentium II Deschutes core	1	32 KB	128 KB	0.25 µm or 0.18 µm	66 MHz	Socket 370
Celeron Coppermine	Coppermine	Pentium III Coppermine core	1	32 KB	128 KB	0.18 µm	66MHz or 100MHz	Socket 370
Celeron Tualatin	Tualatin	Pentium III Tualatin core	1	32 KB	256 KB	0.13 µm	100 MHz	Socket 370
Celeron Willamette	Willamette	Pentium 4 Willamette core	1	8 KB	128 KB	0.18 µm	400 MHz	Socket 478
Celeron Northwood	Northwood	Pentium 4 Northwood core	1	8 KB	128 KB	0.13 µm	400 MHz	Socket 478
Celeron D	Prescott	Pentium 4 Prescott core	1	16 KB	256 KB	90 nm or 65 nm	533 MHz	Socket 478 or Socket 775
Celeron 400 Series	Conroe-L	Core 2 Duo	1	64 KB	512 KB	65 nm	800 MHz	Socket 775
Celeron E1000 Series	Allendale	Core 2 Duo	2	64 KB	512 KB	65 nm	800 MHz	Socket 775

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.
