3090 is nowhere near a titan, titan v-ram pool should be 32gb+. 24gb is basically what u would expect the 3080ti to sit at.
then about 3080.
3080 is a budget card sold for top end money. Anything below 16gb of v-ram has no future simple as that.
I would not even consider the card as a 3060 option.
People are currently looking through this generation glasses. Next generation baseline for v-ram will be 16gb of memory. the base line will go up massively.
This reminds me of a 580 1,5gb, totally solid gpu performance and memory performance, v-ram was fine for ultra settings on any game until PS4 games arrived. It couldn't even run unity or watch dogs on any setting because v-ram bottleneck. Now it probably won't be as bad for the 3080, but expect medium settings being a thing for the card through the entire generation if not low with it.
Any gpu at 400+ when next gen consoles are out needs 16gb of v-ram modules.
10gb makes absolute no sense at all in any way other then they eyeballed for that number. The only way that card has any reason to exist is if its dirt cheap like 200 bucks. And we all know that won't be the case.
It's clear to me that the entire 3000 series besides the 3090 is going to be replaced in 6 months with proper versions when amd has there cards on the market. Anybody buying into these cards will be burned hard.
And for me with a 1080ti, i will be sitting this clusterfuck of a card generation out until they offer something half decent.
