The Intel
®
Xeon™ processor MP with up to 2
-
MB L3 cache on the 0.13 micron process is
designed for high-performance multi-processor server applications. Based on the Intel
®
NetBurst™ microarchitecture and the new Hyper-Threading Technology, it is binary compatible
with previous Intel Architecture (IA-32) processors. The Intel Xeon processor MP with up to 2
-
MB L3 cache is scalable to four processors in a multiprocessor system providing exceptional
performance for applications running on advanced operating systems such as Microsoft
Windows* XP and Windows* 2000 operating systems, Linux*, and UNIX*. The Intel Xeon
processor MP with up to 2 MB L3 cache delivers compute power at unparalleled value and
flexibility for internet infrastructure and departmental server applications. The Intel NetBurst
microarchitecture 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.
