designed to meet the demands of front-end, mid-range

and higher servers. The Pentium III Xeon processor

combines features such as Streaming SIMD Extensions

and faster operating frequency, with proven Intel

characteristics such as architectural compatibility with

past microprocessors and Dynamic Execution and

Dual Independent Bus architecture of the P6 microarchitecture.

The Pentium III Xeon processor brand

name represents the superior performance, availability

and flexible scalability required by front-end, mid-range

and higher server customers at breakthrough

price/performance.

The Pentium III Xeon processor at 1 GHz (256 KB),

validated in 2-way configurations, delivers leading

price/performance for value entry server platforms.

The Pentium III Xeon processor at 700 and 900 MHz

(1 MB– 2 MB), validated in 4-way, 8-way and greater

configurations, delivers enterprise-class performance

for high-end platforms. Streaming SIMD Extensions

in server applications provide network performance

headroom via benefits to TCP/IP Internet applications

as well as performance improvements to memory or

cache-intensive applications. Servers based on the

Pentium III Xeon processor will continue to provide

enterprise-class performance for high-end platforms

and leading value and performance.

Intel Pentium III Xeon processors are available at

speeds up to 900 MHz for multiprocessor servers

and 1 GHz for dual processor servers to provide the

best Intel performance available for applications running

on advanced operating systems such as Windows*

2000 Datacenter, NetWare,* Linux* and UNIX.* Intel

Pentium III Xeon processors are available in 2-, 4-,

8-way and beyond platform solutions, providing

scalability to meet most platform computing needs.

The Pentium III Xeon processor is supported by the

processor systems and 1 MB or 2 MB (700 MHz and
