Intel Xeon MP (Tulsa) processors
Introduction: August 2006
The Xeon brand refers to many families of Intel's x86 multiprocessing CPUs - for dual-processor (DP) and multi-processor (MP) configuration on a single motherboard targeted at non-consumer markets of server and workstation computers, and also at blade servers and embedded systems. 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. Intel's (non-x86) IA-64 processors are called Itanium, not Xeon.
The Tulsa core
Released on 29 August 2006, the 7100 series, codenamed Tulsa (product code 80550), was an improved version of Paxville MP, built on a 65 nm process, with 2MB of L2 cache (1MB per core) and up to 16MB of L3 cache. It used Socket 604. Tulsa was released in two lines: the N-line used a 667MT/s FSB, and the M-line used an 800MT/s FSB. The N-line ranged from 2.5 to 3.5GHz (model numbers 7110N-7150N), and the M-line ranged from 2.6 to 3.4GHz (model numbers 7110M-7140M). L3 cache ranged from 4MB to 16MB across the models.
