Oh phooey on you....the 166 without question uses the same dies as the 200.
I did do the test you mentioned...

A mickey mouse performance loop popular back in the dark age of 386's. IE
the 200 got a rating of 1150, the 100 got 575. Not the best but all I
have on there right now.

Well you will have to burn with anticipation because I'm done playing today.
Try your own hardware.
