I feel the exact opposite. There are too many! There are now nine models of the 4000-series, and that's not including laptop models or the cancelled 4080 12 GB.
IMO, there should be 5 models at the maximum. I shouldn't have to sit here and do a bunch of research to find out if the 4070 SUPER is faster than a 4070 Ti, and whether I should go for a 4070 SUPER Ti.
4060, 4070, 4080, 4090. That's all they ever needed. Budget, mid-grade, enthusiast, top-of-the-line. That's all that's needed.
Though given that NVidia seems to release its consumer GPUs once every 2 years (20 series in late 2018, 30-series late 2020, 40 series in late 2022), I wonder if this is more of a marketing ploy - release the main series once every 2 years, but bring our "super" refreshers in the middle of the cycle to make sure you're still in the news, and get some segment of consumers / gamers to upgrade to those.
