Probably not quite enough raw MIPS in 1987, but people have since ported it: http://gerph.org/riscos/ramble/doomplus.html

Maybe it was more a lack of the DOOM source code or know-how?

According to https://en.wikipedia.org/wiki/Instructions_per_second#Millio... the ARM2 at 8MHz was 4MIPS. The 386DX at 33MHz was 4.3MIPS. The 8MHz 68000 was 1.4MIPS.

Of course there could be other things that made it hard, such as too few bus cycles when running the 8-bit chunky graphics mode? Or that sound did not use DMA(I don't know if the Archimedes had sound DMA) or that the CPU had to mix samples instead of the sound hardware doing it?
