关于 Intel Pentium II Xeon

Pentium II Xeon 于 1998 年 6 月作为英特尔的新服务器和工作站处理器系列推出。PII Xeon 内核采用 0.25 微米工艺制造，与 Pentium II 的内核没有太大区别 。它增加了对四核 CPU 系统甚至一个系统中的 8 个 CPU 的多处理支持以及一些增强功能，比如对超过 4GB 内存的支持。性能和架构的最大差异来自 PII Xeon 的 L2 缓存，大小为 512KB、1MB 甚至 2 MB，并以全时钟速度运行，而 Pentium II 仅提供 512KB L2 缓存，以 CPU 时钟速度的一半运行。

PII Xeon 还引入了 Intel 迄今为止最大的处理器模块（大约是 Pentium II 盒的两倍），包括 CPU 内核和多达四个 512KB L2 缓存芯片。

Introduction

The Pentium II Xeon was introduced in June 1998 as Intel’s new line of server and workstation processors. The PII Xeon core, manufactured in a .25 micron process, is not much different from the Pentium II’s core. It added multiprocessing support for quad CPU systems and even 8 CPUs in one system and a few enhancements, such as support for more than 4GB of memory. The biggest difference in both performance and architecture comes from the PII Xeon’s L2-cache, at 512KB, 1 or even 2 MB and running at full clockspeed, while the Pentium II was only offered with a 512KB L2 cache running at half CPU clockspeed.

The PII Xeon also introduced Intel’s biggest processor module so far (about twice the size of a Pentium II cartridge) to include the CPU core and up to four 512KB L2 cache chips.
