I wrote several ago... that I thought that the improvement to the
80387 chip mask, which increased the 'effeciency' of production per
clock tick --  which basically had been a side effect of producing
a 33 Mhz model, had been been implemented across the board and that
all intel 80387's had now received this 'improvement'.
(Not a quote but the basic gist of it...)
Per PCWEEK 10/1/1990 pg 4.
Intel Soups up 387 Coprocessor
(reprinted with out permission, and edited by me for brevity...)
... will be shipping 16, 20 & 25 Mhz versions ... as much as 20% faster...
.... by use of enhanced microcode....  List price, 16 Mhz $ 570 (Quan 1)
20 Mhz $ 647 (quan 1),  25 Mhz $ 814 (quan 1).
Hope this clears it up.  It isn;t clear that the old verison
is either going to be discounted heavily (although the price has been
dropping on the street) or discontinued...
