All Celeron Models

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 IIDeschutes 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 IIITualatin 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 4Northwood 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 LGA775
Celeron 400 Series Conroe-L Core 2 Duo 1 64 KB 512 KB 65 nm 800 MHz Socket LGA775
Celeron E1000 Series Allendale Core 2 Duo 2 64 KB 512 KB 65 nm 800 MHz Socket LGA775
Celeron E3000 Series Penryn Core 2 Duo 2 64 KB 1 MB 45 nm 800 MHz Socket LGA775

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.
