The '''Intel Xeon''' is a brand of high-performance, desktop, [[x86]] [[microprocessors]] designed by [[Intel]] intended for use in servers and high-end workstations environments. The Xeon brand, which first appeared in 1998 spans two micro-architecture generations including [[Intel NetBurst (microarchitecture)]] and [[Intel Core (microarchitecture)|core]].

Xeon CPUs share the same features as the [[Pentium 4]] and [[Core 2 Duo]]/[[Core 2 Quad|Quad]] desktop [[microprocessors]]. These CPUs can work in dual and quad systems and even in an 8-way setup. Likewise, the Xeon brand is usually designed with a much larger level 2 and level 3 cache.

'''Xeon''' (pronounced ''"Zee-On"'') is an extended family of high-performance [[x86]] microprocessors developed by [[Intel]] for server environments and non-consumer workstations. Over the years Xeon has grown to focus on high-bandwidth, large-memory, and highly concurrent workloads. Xeon processors typically incorporate a large number of [[cores]], large [[cache]], and support for large amount of [[main memory|memory]]. Xeon offers models for both [[uniprocessor]] or [[multiprocessor]]s.
