List of Intel CPU microarchitectures

The following is a "partial" list of Intel CPU microarchitectures. The list is "not" complete.

x86 microarchitectures

* i386 -- First 32-bit x86 processor
* i486 -- Intel's second-generation of 32-bit x86 processors
* P5 -- Original Pentium microprocessors
* P6 -- Used in Pentium Pro, Pentium II, Pentium II Xeon, Pentium III, and Pentium III Xeon microprocessors
* NetBurst -- Used in Pentium 4, Pentium D, and some Xeon microprocessors. Commonly referred to as the P7 microarchitecture although its internal name was P68 ("P7" was used for Itanium).
* Pentium M -- Updated version of Pentium III's P6 microarchitecture designed from the ground up for mobile computing:* Enhanced Pentium M -- Updated, dual core version of the Pentium M microarchitecture used in Core microprocessors.
* Core -- New microarchitecture, based on the P6 architecture, used in Core 2 and Xeon microprocessors, built on a 65nm process.:* Penryn -- 45nm shrink of the Core microarchitecture with larger cache, faster FSB and clock speeds, and SSE4.1 instructions.
* Atom -- Low-power, in-order x86-64 processor for use in Mobile Internet Devices.
* Larrabee -- Multi-core in-order x86-64 processor with wide SIMD vector units and texture sampling hardware for use in graphics. Initially on a 45nm process, the 32 core version expected to be released in 2009.
* Nehalem -- Expected to be released in 2008, built on a 45nm process. It will be an enhanced version of the Core microarchitecture.:* Westmere -- 32nm shrink of the Nehalem microarchitecture with several new features, expected around 2009.
* Sandy Bridge -- Future Intel microarchitecture, expected around 2010, based on a 32nm process. Formerly called Gesher but renamed in 2007.:* Ivy Bridge -- 22nm shrink of the Sandy Bridge microarchitecture, expected around 2011.
* Haswell -- Future Intel microarchitecture, expected around 2012, based on a 22nm process.

Itanium microarchitectures

* Merced microarchitecture -- Original, flawed Fact|date=July 2008 Itanium microarchitecture. Used only in the first Itanium microprocessors.
* McKinley microarchitecture -- Enhanced microarchitecture used in the first two generations of the Itanium 2 microprocessor.:* Montecito microarchitecture -- Enhanced "McKinley" microarchitecture used in the Itanium 2 9000- and 9100-series of processors. Added dual core, coarse multithreading, and other improvements.
* Tukwila microarchitecture -- Future Itanium microarchitecture adding integrated memory controllers, quad core support, and other improvements.
* Poulson -- Future Itanium processor said to feature a new microarchitecturecite web | url=http://www.xbitlabs.com/news/cpu/display/20070619230827.html | title=Intel Plans to change Itanium Micro-Architecture | date=June 19, 2007 | author=Anton Shilov | publisher=X-bit Labs | accessdate=2007-10-05] .
