next gen will use 7nm EUV from Samsung Foundries. Why they did not choose TSMC, despite having free capacity ?
How do you know that they don't choose both? Nvidia is Dual-Sourcing since Pascal and there is no reason to believe that they don't use TSMC again. Could be just next gen small Chips like with Pascal. Digitimes already mentioned, that Nvidia also has TSMC 7nm contracts for this year.
