Intel 486 CPU announced April 10, 1989

Gaming and “killer apps”

  • DOOM is repeatedly cited as the 486’s killer app; a DX2‑66 with VLB graphics is remembered as a sweet spot for smooth play.
  • Other games referenced as 486 milestones: Ultima 7, Strike Commander, Doom II, Rise of the Triad, Duke Nukem 3D, early Quake at low resolutions.
  • 8 MB RAM on a 486 is recalled as making you “king” for gaming and multimedia (CD‑ROM, MPEG‑1 video).

Impact vs. Amiga and 68k systems

  • Many argue the DX2‑66 effectively ended the Amiga/68k era: brute‑force CPU + flat framebuffers beat custom 2D “bitplane” chipsets once 3D and texture mapping mattered.
  • Amiga AGA and CD32 decisions (planar graphics, limited chunky support, 16‑bit chip RAM, slow memory bandwidth) are described as fatal missteps, compounded by poor corporate management.
  • Some speculate 68k could have been evolved like x86; others counter that its “CISC‑ier” design and shrinking market made it a dead end.

CPU variants, buses, and performance quirks

  • 486 SX vs DX: SX was “fine but no FPU”; 386SX is remembered as notably crippled (16‑bit bus, 24‑bit address).
  • Clock‑doubling/‑tripling (DX2, DX4) led to trade‑offs: sometimes a 50 MHz 486 with a 50 MHz bus beat a faster‑clocked CPU on a slower bus.
  • Pentium 60/66 are seen as hot, expensive, and buggy (FDIV, F0 0F), often poor value vs fast 486s; later Pentiums (75–133) are praised.

OSes, tools, and “workstation‑class” computing

  • The 486 plus DJGPP, RHIDE, Slackware, and VESA linear framebuffers made serious development and X11 on PCs feel “workstation‑like” without RISC workstation prices.
  • People ran BBSes under OS/2, early Linux on 486s, and note that the 386’s MMU really began modern protected‑mode multitasking, with debate over how much the 286’s MMU counted.

Performance trajectory and bloat

  • Discussion contrasts the explosive 80s–90s gains (286→386→486→Pentium) with today’s modest single‑core improvements and clock‑speed plateau after the Pentium 4, tied to the end of Dennard scaling.
  • Some argue software (Windows, Word 97 with real‑time spell/grammar, browsers) drove hardware upgrades as features and bloat grew; others defend these as meaningful functionality, not just bad code.

Nostalgia, economics, and legacy

  • Many recall parents making major financial sacrifices for 386/486 PCs that shaped careers.
  • Retro 486 hardware is now rare and pricey.
  • Linux kernel 7.1 dropping 486 support is noted as the symbolic end of an era, though some question why a modern kernel is needed on such old machines.
