other games, if you google can consume 7-9gb vram, that's 2017-2019. upcoming new games can easily double that, so 16gb is the sweet spot for gpu graphics.
I have a feeling that is exactly what nvidia is trying to do. I mean most people dont plan to upgrade from their gtx 1080ti because it has 11gb and if they have a 2560x1440 monitor, can still even play many games at 4k with that amount of gddr, 10GB for a 3080 this time and age is low, I say that 16gb is minimum for a card like that, even if it was a 12gb would be doable. It's funny, the 3090 24gb x 10gb 3080, nvidia really want people to buy the 3090. Nvidia simply killed the 3080 even before launching it, dead on arrival.
