The Intel® Xeon™ processor with 800 MHz system bus is designed for high-performance
dual-processor workstation and server applications. Based on the Intel® NetBurst™ micro-
architecture and the Hyper-Threading Technology, it is binary compatible with previous Intel
Architecture (IA-32) processors. The Intel Xeon processor with 800 MHz system bus is scalable
to two processors in a multiprocessor system providing exceptional performance for applications
running on advanced operating systems such as Windows XP*, Windows Server* 2003, Linux*,
and UNIX*.
The Intel Xeon processor with 800 MHz system bus
delivers compute power at unparalleled value and
flexibility for powerful workstations, internet
infrastructure, and departmental server applications. The
Intel NetBurst micro-architecture and Hyper-Threading
Technology deliver outstanding performance and
headroom for peak internet server workloads, resulting in
faster response times, support for more users, and
improved scalability.
