By the time enough people had a 486 to play games, Amigas were faster than a 7 MHz 68000 and had more RAM as well. You are unfairly comparing a 1988 computer to a 1993 PC, you might as well be comparing C64 to a PS5. Apples and oranges. A 1988 PC couldn't do it as well as a 1993 PC either.
Amigas by then also had the AGA chipset which could do 256 colours from a palette of 16.7 million colors. Your memories seem to be out of sync.
Lots of Amigas in 1993 had hard drives. Your comment is a really poorly researched.
The Amiga had a GPU which could throw pixels around without the CPU needing to do much, but for 3D games, lots of floating point calculations had to be made. The Motorola CPUs often didn't have FPUs while the 486 had it built into every one. The 486 came out at just the right time for Doom to be workable.
Commodore failed to get the AAA chipset done because Irving Gould defunded the R&D department years before.
Comment about the HDDs wasn't poorly researched - it wasn't researched at all. It's from personal experience. I'm not saying PCs were "better computers" than Amigas, or trying to frame a fair comparison. The post is about what happened to the Amiga, and the fact is it wasn't able to compete with the pace of IBM compatibles as they caught up with it in graphics and sound capabilities. It is indeed a lot like comparing the Amiga to the C64.
Nitpick: the 486 had versions without FPUs, or which had them disabled. I had a 486 SX 25Mhz.
"Because Doom was written to run on early 386 and 486 processors which often lacked a floating-point unit entirely, and its use was slow even when present, the game was written to exclusively use fixed point math." [0]
