The Intel® Pentium® II Xeon™ processor is designed for mid-range to high-end servers and workstations, and is
binary compatible with previous Intel Architecture processors. The Pentium II Xeon processor provides the best
performance available for applications running on advanced operating systems such as Windows* 95, Windows
NT, and UNIX*. The Pentium II Xeon processor is scalable to four processors in a multiprocessor system and
extends the power of the Pentium Pro processor with new features designed to make this processor the right
choice for powerful workstation, advanced server management, and mission-critical applications. Pentium II
Xeon processor-based workstations offer the memory architecture required by the most demanding workstation
applications and workloads. Specific features of the Pentium II Xeon processor address platform manageability
to meet the needs of a robust IT environment, maximize system up time and ensure optimal configuration and
operation of servers. The Pentium II Xeon processor enhances the ability of server platforms to monitor, protect,
and service the processor and its environment.
