Intel has historically named integrated circuit (IC) development projects after geographical names of towns, rivers or mountains near the location of the Intel facility responsible for the IC. Many of these are in the American West, particularly in Oregon (where most of Intel's CPU projects are designed; see well-known project codenames). As Intel's development activities have expanded, this nomenclature has expanded to Israel and India. Some older codenames refer to celestial bodies. There is a pattern with recent desktop processors. Since Core 2 all quad-core desktop processors tend to end in "field" (e.g. Kentsfield, Bloomfield, Lynnfield) and most desktop dual-cores end in "dale" (e.g. Wolfdale, Allendale, Clarkdale), with the exception of Arrandale, a mobile processor codename for the mobile i3/i5/i7s. Platforms consisting of a CPU plus a Southbridge end in "trail" (e.g. Bone Trail, Skull Trail, Pine Trail). Server processors for two sockets now end in "town" (e.g. Harpertown, Gainestown, Gulftown, Jaketown), while server processors for four or more sockets end in "ton" (Tigerton, Dunnington, Beckton).
Intel maintains a website http://ark.intel.com/ that lists the codenames for all publicly released products.
The following table lists known Intel codenames along with a brief explanation of their meaning and their likely namesake, and the year of their earliest known public appearance.
