|    68010 <--> 80186
....the 80186 will be quite a bit faster than the 8086, due to new
instructions. The 68010 was mainly released to allow demand paging, and
it is not much of an improvement. This is probably not very fair to the
68010.
|    68020 <--> 80286
....this is a 32 bit bus vs a 16 bit buss, and linear vs segmented
addressing. I think the 80386 is a better comparison in this case.
|    68030 <--> 80386
....I would expect the 68030 to be faster When the 486 comes out it is
supposed to have separate data and operation busses, including address,
so it *should* be a better comparison.

|And from what I hear, the 68030 blows the 80386 out of the water...
....the only benchmarks I have seen indicate that the 68030 is about
40-60% faster with the same speed memory. I'm not sure what the
price/performance ratio is.

It's very hard to compare these processors exactly, since their features
don't match. For many things the 80386 is better because it's so much
cheaper as a package. The <$3000 AT style machines will run Xenix/386
and still stay under $5k for hardware and software for a "personal
machine" sized system with 2-3MB memory and a few serial ports for uucp.
