Can it run Doom? This thread says yes
AMD Am386 released March 2, 1991
From court fights to Doom nights: the ‘late’ AMD chip fans swear by
TLDR: AMD’s Am386 arrived in 1991 after IBM shunned Intel’s 386 and years of legal fights, not because AMD couldn’t clone chips. Commenters split between blaming Intel or IBM, while nostalgia roars: yes, a 386 can run Windows 95 and Doom II, proving politics—not tech—set the timeline.
AMD’s Am386 dropped on March 2, 1991—years after Intel’s shiny 386—and the comments are clear: the “delay” was drama, not incompetence. Readers point to IBM initially rejecting the 386 to protect its pricier minicomputers, and a long, messy legal war where Intel tried everything, even treating “386” like a trademark. The thread splits into two camps: “Intel got greedy” versus “IBM guarded its cash cow”, but everyone agrees the courtroom slog bled AMD while the clock ticked. Nostalgia then kicks the door open: Zardoz84 flexes a 386 that ran Windows 95 (slow but alive), booted DOS and played Doom II, with a later math coprocessor add‑on to crunch numbers. Translation for non‑nerds: a math chip that made spreadsheets and 3D games less painful.
Then comes the retro hot take: burnt‑resistor says Texas Instruments did the same dance with its TMS9900, snubbing hobbyists, and dreams of a souped‑up homebrew build. Jokes fly—“Can it run Doom?” becomes the rallying cry—while another chorus celebrates the legendary DX40-to-486 upgrade glow‑up. Underneath the memes, the comment section rewrites history: AMD’s 386 didn’t crawl in late; it fought through corporate politics and courtroom theatrics to show up anyway. And yes, fans still want to build one.
Key Points
- •AMD’s Am386 launched on March 2, 1991, nearly six years after Intel’s 80386 (October 17, 1985).
- •IBM’s earlier second-sourcing demands enabled AMD to produce 8088/8086 and 80286, but IBM initially declined the 386, so Intel did not extend second-sourcing for it.
- •IBM feared 386-based PCs would cannibalize its profitable minicomputer line (e.g., System/36), viewing a potential $10,000 386 PC as a threat to $20,000 systems.
- •Compaq’s 1986 386-based PC pushed IBM to adopt 386 PCs within a year; IBM then manufactured 386/486 chips itself, starting 386 production in early April 1989.
- •AMD engineered a 386-compatible design in about two years, but protracted litigation with Intel (lasting until 1995; ~$100M) delayed market entry, including trademark and licensing disputes.
