486 will be little faster in communicating
with the coprocessor as signals do not have to go from
one package to onother. Since communication is within
the same package, 486-25 may even come out little 
faster than 386-33 with same amount of memory caching.
However, with high cache memory or with low math coprocessor
intensive applications, we would be comparing apples and
oranges.
