'''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.
