The 64-bit Intel® Xeon™ processor with 2 MB L2 cache 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 64-bit Intel Xeon processor with 2 MB L2 cache 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 64-bit Intel Xeon processor with 2 MB L2 cache 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.
