Intel Pentium III Celeron Processor

关于 Intel Pentium III Celeron

具有 Coppermine-128 内核的 Intel Celeron 处理器于 2000 年 3 月 29 日推出。这些处理器的时钟频率从 533 到 1100 MHz，从 800 MHz 的 Celeron 开始，Celeron 的总线时钟从 66 MHz 提高到 100 MHz。FC-PGA 封装中的赛扬需要第二代 Socket 370 作为主板接口。

由于制造成本低，赛扬主要安装在廉价的预算 PC 中。

Introduction

Second generation Celeron, based on the Pentium III.

The Celeron family is a line of budget x86 processors based on Pentium P6 designs. It is marketed by Intel as a second line to complement their more expensive but higher-performance Pentium CPUs. The first Celeron was introduced in April 1998 and based on the Pentium II. Later versions are based on the Pentium III and Pentium 4 designs.

The Celeron product concept was introduced by Intel in response to the company’s loss of low-end market share, in particular to Cyrix’s 6x86 and AMD’s K6, but also to other competers such as the IDT Winchip. Intel’s venerable Pentium MMX was no longer performance competitive and although a faster Pentium MMX would be cheap to make and technically straightforward, Intel preferred to move away from the industry standard Socket 7 platform (for which competitors made drop-in replacement CPUs) and produced a budget part that was pin-compatible with their high-end Pentium II product (Slot 1). For both technical and legal reasons, competitors had difficulty making Slot 1 parts.
