Its funny how first everyone complains about miners 'they dun took our cards'... and when Nvidia maximizes the amount of sellable GPUs out of their silicon/fab capacity those same people complain about cut down GPUs.
You do realize that the reason Nvidia does this is because they can sell them and they can sell them because demand is still sky high. Beyond that, not much to see here... but really, this is Nvidia trying to stabilize the market and along with maximizing profit, feeding the market's high demand. You have to understand that this is a win-win situation.
- More fab capacity goes towards GP104 because margin/demand peaks in the segment of 1070/1080. Move relatively low amounts of units with relatively solid margins, as opposed to fabbing for GP106 to move more units with lower margins. The 1070 is one of the cards that is still completely oddly priced right now, because of excessive miner demand in the recent past. For many people the only feasible alternative is stepping down to 1060 6GB - not up to a 1070ti or 1080, which is at a high price point.
- Nvidia thus has a chance to create more GP104 1070tis and they utilize nearly every failed GP104 as a 1070, or a 1060, feeding the lower segments along the way.
