You'd need memory chips with double the memory capacity to slap the extra vram in, at least without altering the memory bus width. And indeed, some third party modded entries like that seem to have shown up: https://www.tomshardware.com/pc-components/gpus/nvidia-gaming-gpus-modded-with-2x-vram-for-ai-workloads https://www.tomshardware.com/pc-components/gpus/nvidia-gamin... As far as official products, I think the real reason another commentator mentioned is that they don't want to cannibalize their more powerful card sales. I know I'd be interested in a lower powered card with a lot of vram just to get my foot in the door, that is why I bought a RTX 3060 12GB which is unimpressive for gaming but actually had the second most vram available in that generation. Nvidia seem to have noticed this mistake and later released a crappier 8GB version to replace it. I think if the market reacted to create a product like this to compete with nvidia they'd pretty quickly release something to fit the need, but as it is they don't have too.
