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 memory. Xeon offers models for both uniprocessor or multiprocessors.
