I'm missing something else.
If Nvidia is maxed out on production of existing cards, how are they finding the capacity to tool up four brand new designs, why would they not use that capacity to just build more of the existing design.
Unless its a components problem and the new mining cards will not use the same parts?
Which would imply they have production capacity sitting idle right now?
For the 3060 it was probably already factored into Nvidia's chip production capacity.
For the new mining processors they may be repurposing old chips or releasing lower binned ones with memory they can get cheap.
It will be interesting to see how they price the mining ones and how well outside of massive farms they are received if widely available.
