Xeon Processor Intel Inside

The sign is used by Intel Xeon processor since 1998 to indicate processors designed for server systems based on x86 mid-range. The purpose of the maker, are planned for small business servers that essential support a limited amount from users and are thus in the area of desktop processors, and those Planned for superior servers (Itanium and Itanium 2), range (and price ) higher.

Though historically completely of the various projects Xeon processor that have followed over time have Ever been came from the desktop counterparts, are generally characterized by a larger cache, higher reliability, support for multiprocessor architectures and a different socket.

The first Xeon processor to arrive on the market was derived from the second-generation desktop processor Pentium II and to underline that heritage the brand name originally included just the name of the CPU from which it came, the first Xeon was then marketed as "Pentium II Xeon" . Subsequently, with the transition to the Pentium III Xeon range was also updated for the occasion which became "Pentium III Xeon processors."

Since 2001, Intel Pentium 4 Net Burst architecture passed for the function and selected to simplify the mark indicating the new processors simply as "Xeon" but differentiated according to the type of systems they would have been addressed: Xeon DP (acronym of "Dual Processors") to indicate those designed for dual processor systems, and Xeon MP (which stands for "Multi Processors") to indicate those designed for multiprocessor systems.

For many years, the competitor of  Athlon MP CPU Xeon processor was made by competitor Advanced Micro Devices, but that was never specially successful among the public since 2003, however, came the Opteron, which had superior operation to  corresponding models of  Xeon processor offered Intel at that time. Subsequent developments from Intel allowed to gradually bridge the gaps (for example, adoption of a bus dedicated to each pair of processors so as to limit the "bottleneck" in communications between the CPU and chipset), to resume leadership performance by abandoning NetBurst architecture in favor of Intel Core micro architecture, which was favored by the general efficiency from the pure increase in clock frequency.

This dominance proceeded in 2009 with the issue of the first Xeon-based Nehalem architecture, next to the "Core", and with integrated RAM memory controller and the serial bus called Intel Quick Path Interconnect (QPI)
