They don't even offer that much VRAM on cards aimed at those price-insensitive customers, Nvidias current lineup maxes out at 48GB for GDDR-based models or 80GB for HBM-based models. Even if money is no object there's still practical engineering limits on how much memory they can put on a card without sacrificing bandwidth.

So when is Micron due to introduce higher density dram chips? Nvidia is limited to what's available from RAM manufacturers there.

Samsung has announced GDDR6W which doubles the density, but also doubles the pin count (so same amount of VRAM in total, but takes up half the space on the board). I'm assuming that companies will save any more density improvements for GDDR7 which is rumored to be used in next-gen GPUs (probably 2nd half 2024).
