    I'm not sure how you derived this, unless you were dealing with
clock speed only.  The 486 is 2-3 times faster than the 386 on identical
clock speeds (if Intel and a number of reviewers are to be believed). 
This being the case, the 486/25 must be significantly faster than the
386/33.  And in fact, I have seen benchmark results that tend to
indicate that it is faster.
