Intel Processor Code Names

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 the state of 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, Clarksdale), 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/#codenamesall 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

See this diagram. These all are the code names of processor of past , present and for future.

 NetBurst
The NetBurst microarchitecture, called P68 inside Intel, was the successor to the P6 microarchitecture in the
x86 family of CPUs made by Intel. The first CPU to use this architecture was the Willamette core of the Pentium 4, released on November 20, 2000 and the first of the Pentium 4 CPUs; all subsequent Pentium 4 and Pentium D variants have also been based on NetBurst. In mid 2001, Intel released the Foster core, which was also based on NetBurst, thus switching the Xeon CPUs to the new architecture as well. Pentium 4-based Celeron CPUs also use the NetBurst architecture. NetBurst was replaced with the Core microarchitecture, released in July 2006. technology in The NetBurst microarchitecture includes features such as Hyper Pipelined Technology and Rapid

Execution Engine which are firsts in this particular microarchitecture.

P6
The P6 microarchitecture is the sixth generation Intel x86 microarchitecture, implemented by the Pentium Pro microprocessor that was introduced in November 1995. It is sometimes referred to as i686.[citation needed] It was succeeded by the NetBurst microarchitecture in 2000, but eventually revived in the Pentium M line of microprocessors. The successor to the Pentium M variant of the P6 microarchitecture is the Core microarchitecture.

Yonah (microprocessor)
The first processors using the brand appeared in notebook computers in early 2007. Those processors, named Pentium T2060, T2080, and T2130,[2] had the 32-bit Pentium M-derived Yonah core, and closely resembled the Core Duo T2050 processor with the exception of having 1 MB of L2 cache instead of 2 MB. All three of them had a 533 MHz FSB connecting the CPU with the memory. Intel developed the Pentium Dual-Core at the request of laptop manufacturers.

Conroe (microprocessor)#Allendale
Subsequently, on June 3, 2007, Intel released the desktop Pentium Dual-Core branded processors known as the Pentium E2140 and E2160. An E2180 model was released later in September 2007. These processors support the Intel 64 extensions, being based on the newer, 64-bit Allendale core with Core microarchitecture. These closely resembled the Core 2 Duo E4300 processor with the exception of having 1 MB of L2 cache instead of 2 MB. Both of them had an 800 MHz FSB. They targeted the budget market above the Intel Celeron (Conroe-L single-core series) processors featuring only 512 KB of L2 cache. Such a step marked a change in the Pentium brand, relegating it to the budget segment rather than its former position as the mainstream/premium brand.These CPUs are highly overclockable.

Merom (microprocessor)
The mobile version of the Allendale processor, the Merom-2M, was also introduced in 2007, featuring 1MB of L2 cache but only 533 MT/s FSB with the T23xx processors. The bus clock was subsequently raised to 667 MT/s with the T3xxx Pentium processors that are made from the same dies.
Intel Atom is the brand name for a line of ultra-low-voltage IA-32 and x86-64 CPUs (or microprocessors) from Intel, originally designed in 45 nm CMOS with subsequent models, codenamed Cedar, using a 32 nm process.[2] Atom is mainly used in netbooks, nettops, embedded applications ranging from health care to advanced robotics, and mobile internet devices (MIDs). For Atom system on chips designed for smartphones and tablets see Atom (system on chip).
Atom
Atom processors are based on the Bonnell microarchitecture. On 21 December 2009, Intel announced the Pine Trail platform, including new Atom processor code-named Pineview (Atom N450), with total kit power consumption down 20%.[5] On 28 December 2011, Intel updated the Atom line with the Cedar processors.

Wolfdale
Wolfdale is the code name for a processor from Intel that is sold in varying configurations as Core 2 Duo, Celeron, Pentium and Xeon. In Intel's Tick-Tock cycle, the 2007/2008 "Tick" was Penryn microarchitecture, the shrink of the Core microarchitecture to 45 nanometers as CPUID model 23. This replaced the Conroe processor with Wolfdale.
The Wolfdale chips come in two sizes, with 6 MB and 3 MB L2 cache, the smaller version is commonly called Wolfdale-3M.
The mobile version of Wolfdale is Penryn and the dual-socket server version is Wolfdale-DP. The Yorkfield desktop processor is a quad-core Multi-chip module of Wolfdale.
Wolfdale has been replaced by Nehalem based Clarkdale and its Sandy Bridge successor.

Ivy Bridge

 Ivy Bridge is the codename for Intel's 22 nm die shrink of the Sandy Bridge microarchitecture based on tri-gate ("3D") transistors. Ivy Bridge processors will be backwards-compatible with the Sandy Bridge platform, but might require a firmware update (vendor specific). Intel has released new 7-series Panther Point chipsets with integrated USB 3.0 to complement Ivy Bridge.
Intel announced that volume production of Ivy Bridge chips began in the third quarter of 2011.[3] Quad-core and dual-core-mobile models launched on 29 April and 31 May 2012 respectively. Meanwhile, Core i3 desktop processors are said to arrive in the third quarer of 2012.

Sandy Bridge
Sandy Bridge is the codename for a microarchitecture developed by Intel beginning in 2005 for central processing units in computers to replace the Nehalem microarchitecture. Intel demonstrated a Sandy Bridge processor in 2009, and released first products based on the architecture in January 2011 under the Core brand.Originally, implementations targeted a 32 nanometer manufacturing process based on planar double-gate transistors. Subsequent products, codenamed Ivy Bridge, use a 22 nanometer process. The Ivy Bridge die shrink, known in the Intel Tick-Tock model as the "tick", is based on 3D tri-gate transistors. Intel demonstrated Ivy Bridge processors in 2011.

Allendale
Allendale was originally the name for the E4000 processors, which use a low-cost version of the Conroe core. They feature a lower front side bus with 800 mHz instead of 1066 mHz and only half the L2 Cache (2 MB, Like the E6300 and the E6400), offering a smaller die size and therefore greater yields . Most media have subsequently applied the name Allendale to all LGA 775 processors with steppings L2 and M0, while Intel refers to all of these as Conroe.
The Core 2 Duo E4300[6] uses an Allendale core, released on January 21, 2007. Allendale processors are produced in the LGA 775 form factor, on the 65 nm process node. Initial list price per processor in quantities of one thousand for the E4300 was US$163. A standard OEM price was US$175, or US$189 for a retail package. The price was cut on April 22, 2007, when the E4400 was released at $133 and the E4300 dropped to $113. A new E2000 series of Allendale processors with half their L2 cache disabled was released in mid-June 2007 under the Pentium Dual-Core brand name. The working cache memory was reduced by half again when the Allendale core was released under Intel's Celeron brand; the Celeron E1000 processors have a 512k L2 cache shared between its two cores.

Nehalem
Nehalem (pronounced /n?'he?l?m/) is the codename for an Intel processor microarchitecture, successor to the Core microarchitecture. Nehalem processors use the 45 nm process. A preview system with two Nehalem processors was shown at Intel Developer Forum in 2007. The first processor released with the Nehalem architecture was the desktop Core i7, which was released in November 2008.
Nehalem, a recycled codename, refers to a completely different architecture from Netburst, although Nehalem still has some things in common with NetBurst. Nehalem-based microprocessors utilize higher clock speeds and are more energy-efficient than Penryn microprocessors. Hyper-threading is reintroduced along with a reduction in L2, which has been incorporated as L3 Cache which is usable by all cores. Nehalem was replaced with the Sandy Bridge microarchitecture, released in January 2011.

Conroe
Conroe is the code name for many Intel processors sold as Core 2 Duo, Xeon, Pentium Dual-Core and Celeron. It was the first desktop processor to be based on the Core microarchitecture, replacing the NetBurst microarchitecture based Cedar Mill processor. It has product code 80557, which is shared with Allendale and Conroe-L that are very similar but have a smaller L2 cache. Conroe-L has only one processor core and a new CPUID model. The mobile version of Conroe is Merom, the dual-socket server version is Woodcrest, and the quad-core desktop version is Kentsfield. Conroe was subsequently replaced by the 45 nm Wolfdale processor.
