I'm not at all sure what you base that on.  A 486 is about 2.5 to 3 times
faster than a 386 that runs at the same clock speed.  That makes a 386-33 about
half as fast as a 486-25.  Of course, they both are going to run about the same
if you have a disk intensive application and have equivalent disks.  I've used
both: the 486 wins.  On the cost issue: I haven't been able to tell that the
386 alternative is $500 cheaper either, considering how much a 387-33 costs.
