That said, the 030 did make some significant improvements over the 020 when you consider the non-EC parts. The full 030 added on-die MMU and can run at 50MHz (the latter feature being more significant for Amiga machines).
The same is true with the upgrade from the 286 to 386... most of the speed improvement was the higher clock...
I had a 286 clocked at 25mhz

it was quick like a 386 and most software still ran in 8088 mode anyway.
I was going to buy a 386 20mhz mb but my system builder guy convinced me should take the faster 286 and the (more expensive) Tsing video over the Trident
