Intel Xeon UP/DP (Wolfdale) processors

Introduction: November 2007


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 Wolfdale core

On 11 November 2007, Intel released the dual-core CPU (Xeon branded 5200 series) codenamed Wolfdale DP (product code 80573). It was built on a 45 nm process like the desktop Core 2 Duo Wolfdale and the Xeon-SP Wolfdale, featuring Intel 64 (Intel's x86-64 implementation), the XD bit, and Virtualization Technology. Wolfdale had 6MB of shared L2 Cache.
