Before P5
  • 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. A small number of additional instructions.
  • 286: first x86 processor with protected mode including segmentation based virtual memory management. Performance improved by a factor of 3...4 over 8086. Included instructions relating to protected mode.
  • i386: first 32-bit x86 processor. Introduced paging on top of segmentation which is the most commonly used memory protection technology in modern operating systems ever since. Many additional powerful and valuable new instructions.
  • i486: Intel's second generation of 32-bit x86 processors, introduced built-in floating point unit (FPU), 8 KB on-chip L1 cache, and pipelining. Faster per MHz than the 386. Small number of new instructions.
original Pentium microprocessors, first x86 processor with super-scalar architecture, branch prediction and RISC µop decode scheme.
used in Pentium Pro, Pentium II, Pentium II Xeon, Pentium III, and Pentium III Xeon microprocessors. First x86 processor to support SIMD instruction with XMM register implemented, integrated register renaming and out-of-order execution. Some important new instructions, including conditional moves, which allow the avoidance of costly branch instructions. Added 36-bit physical memory addressing, "Physical Address Extension (PAE)".
Commonly referred to as P7 although its internal name was P68 (P7 was used for Itanium). Used in Pentium 4, Pentium D, and some Xeon microprocessors. Very long pipeline. The Prescott was a major architectural revision. Later revisions were the first to feature Intel's x86-64 architecture, enhanced branch prediction and trace cache, and eventually support was added for the NX (No eXecute) bit to implement executable-space protection.
Pentium M
updated version of Pentium III's P6 microarchitecture designed from the ground up for mobile computing and first x86 to support micro-op fusion and smart cache.
Intel Core
reengineered P6-based microarchitecture used in Core 2 and Xeon microprocessors, built on a 65 nm process, supporting x86-64 level SSE instruction and macro-op fusion and enhanced micro-op fusion with a wider front end and decoder, larger out-of-order core and renamed register, support loop stream detector and large shadow register file.
  • Penryn: 45 nm shrink of the Core microarchitecture with larger cache, higher FSB and clock speeds, SSE4.1 instructions, support for XOP and F/SAVE and F/STORE instructions, enhanced register alias table and larger integer register file.
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. Added important powerful new instructions, SSE4.2.
  • Westmere: 32 nm shrink of the Nehalem microarchitecture with several new features.
45 nm, low-power, in-order microarchitecture for use in Atom processors.
  • Saltwell: 32 nm shrink of the Bonnell microarchitecture.
Larrabee (cancelled 2010)
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).
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] First x86 to introduce 256 bit AVX instruction set and implementation of YMM register.
  • Ivy Bridge: 22 nm shrink of the Sandy Bridge microarchitecture released April 28, 2012.
22 nm, out-of-order microarchitecture for use in Atom processors, released May 6, 2013.
  • Airmont: 14 nm shrink of the Silvermont microarchitecture.
22 nm microarchitecture, released June 3, 2013. Added a number of important powerful new instructions, including FMA.
  • Broadwell: 14 nm shrink of the Haswell microarchitecture, released in September 2014. Formerly called Rockwell.
new 14 nm microarchitecture, released August 5, 2015.
14 nm Atom microarchitecture iteration after Silvermont but borrows heavily from Skylake processors (e.g., GPU), released April 2016.[2][3]
  • Goldmont Plus: successor to Goldmont microarchitecture, still based on the 14 nm process, released December 11, 2017.
Ice Lake
new 10 nm microarchitecture, expected in 2019.
  • Tiger Lake: an update of Ice Lake, expected in 2020?

Itanium microarchitectures[edit]

original Itanium microarchitecture. Used only in the first Itanium microprocessors.
enhanced microarchitecture used in the first two generations of the Itanium 2 microprocessor.
enhanced McKinley microarchitecture used in the Itanium 2 9000- and 9100-series of processors. Added dual core, coarse multithreading, and other improvements.
enhanced microarchitecture used in the Itanium 9300 series of processors. Added quad core, SMT, an integrated memory controller, QuickPath Interconnect, and other improvements.
Itanium processor featuring a new microarchitecture.[4]
the last Itanium microarchitecture. It has slightly higher clock speed than Poulson.
