In fact a 25Mhz 486 (the only speed currently available in "production") has
about the same performance as a 33Mhz 386.
The 486 is the first production IC with over 1 Million transistors (I
torched the cover off one a week or two ago, and counted 'em.... - actually
I *did* take the cover off one, its impressive!!)
