No , no, no, you are moving the goalposts , Nvidia and AMD made a super high end segment A.K.A Titan/Fury. You need to acknowledge that.
Why do we not see cards like the dual gpu gtx690 anymore?
They have been replaced with Titan / Fury.
How its cut down, how big the die is, does not matter.
That all was changed with single gpu super high end cards that replaced the dual gpu junk.
Look at the performance and price brackets and names.
Its common sense.
How much has performance risen from the gtx580 to the 680 to the 780 to the 980 to the 1080. The price stayed about the same and the performance went up every time consistently.
Same with every performance tier, performance rose and the price stayed about the same.
Super high end.
