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. 8088 version, with an 8-bit bus, used in the original IBM Personal Computer.
186
included a DMA controller, interrupt controller, timers, and chip select logic. A small number of additional instructions. The 80188 was a version with an 8-bit bus.
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.
P5
original Pentium microprocessors, first x86 processor with super-scalar architecture and branch prediction.
P6
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, RISC µop decode scheme, 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)".
NetBurst
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.
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. Added important powerful new instructions, SSE4.2.
  • Westmere: 32 nm shrink of the Nehalem microarchitecture with several new features.
Bonnell
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
32 nm microarchitecture, released January 9, 2011. Formerly called Gesher but renamed in 2007.[1] First x86 to introduce 256 bit AVX instruction set and implementation of YMM register.
  • Ivy Bridge: successor to Sandy Bridge, using 22 nm process, released in April 2012.
Silvermont
22 nm, out-of-order microarchitecture for use in Atom processors, released May 6, 2013.
  • Airmont: 14 nm shrink of the Silvermont microarchitecture.
Haswell
22 nm microarchitecture, released June 3, 2013. Added a number of new instructions, including FMA.
  • Broadwell: 14 nm shrink of the Haswell microarchitecture, released in September 2014. Formerly called Rockwell.
Skylake
14 nm microarchitecture, released August 5, 2015.
  • Kaby Lake: successor to Skylake, released in August 2016, broke Intel's Tick-Tock schedule due to delays with the 10 nm process.
    • Amber Lake: ultra low power, mobile-only successor of Kaby Lake, using 14+ nm process, released in August 2018 (no architecture changes)[2]
    • Whiskey Lake: mobile-only successor to Kaby Lake Refresh, using 14++ nm process, released in August 2018 (has hardware mitigations for some vulnerabilities)[2]
  • Coffee Lake: successor to Kaby Lake, using 14+ nm process, released in October 2017
  • Cascade Lake: server and high-end desktop successor to Kaby Lake-X, using 14 nm process, released in April 2019
  • Comet Lake: successor to Coffee Lake, using 14++ nm process, released in August 2019
Goldmont
14 nm Atom microarchitecture iteration after Silvermont but borrows heavily from Skylake processors (e.g., GPU), released April 2016.[3][4]
  • Goldmont Plus: successor to Goldmont microarchitecture, still based on the 14 nm process, released December 11, 2017.
Tremont
10 nm Atom microarchitecture iteration after Goldmont Plus.[5]
Palm Cove
After releasing the Palm Cove core, Intel has changed their microarchitecture naming scheme, decoupling the CPU cores from their manufacturing nodes.[6]

Successor to the Skylake core, first consumer core to include the AVX-512 instruction set.[7] (That's if you don't count Skylake-X as consumer core, which also has AVX-512 and appeared on the market 11 months before Cannon Lake.)
  • Cannon Lake: mobile-only successor of Kaby Lake, using 10 nm process, first and only microarchitecture to implement the Palm Cove core, released in May 2018. Formerly called Skymont, discontinued in December 2019.[8]
Sunny Cove
Successor to the Palm Cove core, first core to include hardware acceleration for SHA hashing algorithms.[9]
  • Ice Lake: low power, mobile-only successor to Whiskey Lake, using 10+ nm process, released in September 2019
  • Cooper Lake: server and high-end desktop successor to Cascade Lake, using 14++ nm process, to be released in 2020
Willow Cove
Successor to the Sunny Cove core, includes new security features and redesigns the cache subsystem.[10]
  • Tiger Lake: successor to Ice Lake, using 10++ nm process, to be released in 2020
  • Rocket Lake: successor to Comet Lake, using 14++ nm process, to be released in 2021[11][12]
Golden Cove
Successor to the Willow Cove core, includes improvements to single threaded performance, AI performance, network and 5G performance and new security features.[13]

Itanium microarchitecturesEdit

McKinley
enhanced microarchitecture used in the first two generations of the Itanium 2 microprocessor.
Montecito
enhanced McKinley microarchitecture used in the Itanium 2 9000- and 9100-series of processors. Added dual core, coarse multithreading, and other improvements.
Tukwila
enhanced microarchitecture used in the Itanium 9300 series of processors. Added quad core, SMT, an integrated memory controller, QuickPath Interconnect, and other improvements.
Poulson
Itanium processor featuring a new microarchitecture.[14]
Kittson
the last Itanium microarchitecture. It has slightly higher clock speed than Poulson.
