It is odd. I had read of it, of course, but for me the revelation was
getting an Acorn Archimedes in 1989, with an 8MHz ARM2, and seeing it
blast past benchmarks of ~8MHz 68K machines such as the Amiga 500 or
Atari 512 ST. It was about 4x faster, I believe.

For me -- being a bit too young for the early days of the 68K family
-- it was not a performance chip, but more about its ability to have
lots of flat memory, unlike the crippled Intel chips that IBM used.

I've heard that before, yes,. and never the IBM comparison.

I suppose it is a matter of what you're more familiar with.

Sinclair's QL used a 68008 and was launched some weeks before the Mac.
Of course Apple's own Lisa was before the Mac, too.

Very soon after came the Amiga and ST -- the "Jackintosh", "power
without the price."
