x86 microarchitectures[edit]

Microarchitecture Pipeline stages
P5 (Pentium) 5
P6 (Pentium Pro) 14
P6 (Pentium 3) 10
NetBurst (Willamette) 20
NetBurst (Northwood) 20
NetBurst (Prescott) 31
NetBurst (Cedar Mill) 31
Core 14
Bonnell 16
8086
First x86 processor; initially a temporary substitute for the iAPX 432 to compete with Motorola, Zilog, and National Semiconductor and to top the successful Z80.
186
Included a DMA controller, interrupt controller, timers, and chip select logic.
286
First x86 processor with protected mode.
i386
First 32-bit x86 processor.
i486
Intel's second-generation of 32-bit x86 processors, included built in floating point unit and pipelining.
P5
Original Pentium microprocessors.
P6
Used in Pentium Pro, Pentium II, Pentium II Xeon, Pentium III, and Pentium III Xeon microprocessors.
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.
NetBurst
Used in Pentium 4, Pentium D, and some Xeon microprocessors. Commonly referred to as P7 although its internal name was P68 (P7 was used for Itanium). Later revisions were the first to feature Intel's x86-64 architecture.
Core
Reengineered P6-based microarchitecture used in Core 2 and Xeon microprocessors, built on a 65 nm process.
Penryn
45 nm shrink of the Core microarchitecture with larger cache, higher FSB and clock speeds, and SSE4.1 instructions.
Nehalem
Released November 17, 2008, built on a 45 nm process and used in the Core i7, Core i5, Core i3 microprocessors. Incorporates the memory controller into the CPU die.
Westmere
32 nm shrink of the Nehalem microarchitecture with several new features.
Sandy Bridge
Released January 9, 2011, built on a 32 nm process and used in the Core i7, Core i5, Core i3 second generation microprocessors, and in Pentium B9XX and Celeron B8XX series. Formerly called Gesher but renamed in 2007.[1]
Ivy Bridge
22 nm shrink of the Sandy Bridge microarchitecture released April 28, 2012.
Haswell
New 22 nm microarchitecture, released June 3, 2013.
Broadwell
14 nm shrink of the Haswell microarchitecture, expected in 2014. Formerly called Rockwell.
Skylake
Future Intel microarchitecture, based on a 14 nm process.
Cannonlake
10 nm shrink of the Skylake microarchitecture. Formerly called Skymont.
Larrabee
Multi-core in-order x86-64 updated version of P5 microarchitecture, with wide SIMD vector units and texture sampling hardware for use in graphics. Cores derived from this microarchitecture are called MIC (Many Integrated Core).
Bonnell
45 nm, low-power, in-order microarchitecture for use in Atom processors.
Saltwell
32 nm shrink of the Bonnell microarchitecture.
Silvermont
22 nm, out-of-order microarchitecture for use in Atom processors.
Airmont
14 nm shrink of the Silvermont microarchitecture.
Goldmont
14 nm Atom microarchitecture.[2][3]

Itanium microarchitectures[edit]

Merced microarchitecture
Original 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
Enhanced microarchitecture used in the Itanium 9300 series of processors. Added quad core, SMT, an integrated memory controller, QuickPath Interconnect, and other improvements.
Poulson microarchitecture
Itanium processor featuring a new microarchitecture.[4]
Kittson microarchitecture
Future Itanium processors.
