  • The Intel 486, officially named i486 and also known as 80486
  • Intel named it DX4 (rather than DX3) as a consequence of litigation with AMD – Advanced Micro Devices over trademarks.
  • a higher-performance follow-up to the Intel 386
  • represents the fourth generation of binary compatible CPUs
  • Gen 1: the 8086 of 1978
  • Gen 2: the Intel 80286 of 1982
  • Gen 3: and 1985’s i386.
  • Designed by Intel, with Pat Gelsinger as chief architect
  • Common manufacturers: Intel, IBM, AMD, Texas Instruments, Harris Semiconductor, UMC, SGS Thomso
