An architecture is a type of CPU. There are 8-bit, 16-bit, 32-bit, 64-bit and even 128-bit architectures, distinguished by RISC or CISC instruction sets. The most prevalent of them all were Intel's x86 architecture.

Contents

x86

The most used architecture in computers. Devices using it includes:

  • Original Xbox
  • Xbox One
  • PlayStation 4
  • First and second generation of ASUS Zenfone Android phones
  • Most PCs and Macs

Itanium

HP and Intel's failed attempt at making a 64-bit architecture before Intel finally switching to the x86-64 architecture with EM64T. Devices using it includes:

  • HP Integrity line of servers
  • Fujitsu PRIMEQUEST line of workstation produced from 2005 to 2011
  • Some SGI workstation produced from 2001

ARM

The most popular architecture for embedded devices. Devices using it includes:

  • Game Boy Advance
  • Wii (Hollywood GPU only)
  • Nintendo Switch
  • Panasonic/Goldstar 3DO
  • Raspberry Pi and other single-board computers
  • Most Android and iOS phones
  • Palm phones running Palm OS 5 or above (also includes Palm Tungsten line of phones)
  • TI-Nspire line of graphing calculators
  • M1 Macs

PowerPC

Devices using it includes:

  • Macintoshes produced from the year 1994 to 2006
  • Xbox 360
  • PlayStation 3
  • GameCube
  • Wii
  • Wii U

MIPS

Devices using it includes:

  • PlayStation 1
  • PlayStation 2
  • Nintendo 64
  • Most old SGI workstations

90's favorite architecture. Devices using it includes:

  • Sega Genesis
  • Commodore Amiga
  • Atari Jaguar and ST
  • Palm phones running Palm OS 4 or below
  • Macintoshes produced from the year 1984 to 1994

IBM System/390

Devices using it includes:

  • IBM ES/9000 series
  • IBM 9672 series

MOS 6502

A very old one. 16-bit devices may use 16-bit WDC 65C816 superset of the MOS 6502 architecture. Devices using it includes:

  • NES/Famicom
  • SNES/Super Famicom
  • Apple ][ (including Apple //c and Apple IIgs)
  • Commodore PET, VIC-20 and 64
  • Atari 2600, 5200, 7600 and Atari 8-bit computers

Zilog Z80

One of Texas Instrument's favorite architecture. Devices using it includes:

  • ZX Spectrum
  • MSX
  • TRS-80
  • Game Boy and Game Boy Color (using a hybrid Z80 and Intel 8086 CPU)
  • Sega Master System
  • Sega Genesis (sound processing only)
  • Old TI graphing Calculators
