| Xeon : |
The Xeon is a brand of multiprocessing- or multi-socket-capable x86 microprocessors from Intel Corporation targeted at the non-consumer server, workstation and embedded system markets.
Intel Xeon processors represent a broad product line to meet a range of demanding performance and energy efficiency requirements for compute-intensive embedded, storage, and communications applications such as: communication infrastructure servers, blades, and appliance, security servers, blades, and appliances, storage servers, blades, and appliances, carrier-grade rack-mount servers, proprietary, non-standard form factors, such as router modules, advancedTCA*-based blades, medical servers, blades, and appliances, industrial control and automation equipment, digital security surveillance applications. A microprocessor incorporates most or all of the functions of a computer’s central processing unit (CPU). The Xeon brand has been maintained over several generations of x86 and x86-64 processors. Older models added the Xeon moniker to the end of the name of their corresponding desktop processor, but more recent models used the name Xeon on its own. The Xeon CPUs generally have more cache than their desktop counterparts in addition to multiprocessing capabilities. The first Xeon-branded processor was the Pentium II Xeon (code-named "Drake"). It was released in 1998, replacing the Pentium Pro in Intel's server lineup. The Pentium II Xeon was a "Deschutes" Pentium II with a full-speed 512 KB, 1 MB, or 2 MB L2 cache. The L2 cache was implemented with custom 512 KB SRAMs developed by Intel. The additional cache required a larger module and thus the Pentium II Xeon used a larger slot, Slot 2. It was supported by the 440GX dual-processor workstation chipset and the 450NX quad- or octo-processor chipset. In 1999, the Pentium II Xeon was replaced by the Pentium III Xeon. Reflecting the incremental changes from the Pentium II "Deschutes" core to the Pentium III "Katmai" core, the first Pentium III Xeon, named "Tanner” and a few cache controller improvements.
