Were just at the itterative part of progress as nvidia didnt attempt to do multi die gpus yet which would be some progress. Iterative releases always tends to be not very exciting, as it takes a gamble to be able to release something new and see if it sticks or not (e.g for gpus, introducing rtx, or amd introducing infinity cache). Iterative releases more or less is a pricing problem to get people excited, as most of the performance gains and work is moreso on TSMC than it is the respective gpu company.
