Samsung started shipping 16GB LPDDR5 modules last year. They are supposedly 1.5x the speed and 20% lower power. Double the stacks from 2 to 4 and moving from 8GB to 16GB gives 64GB. The two extra channels and extra performance gives something like 3x the bandwidth at only a bit more power. That seems perfect for feeding more cores and a larger GPU. I’d love to see a move toward 512-bit HBM3. It seems like the perfect compromise. It doesn’t need expensive silicon interposers and offers decent latency while still having a lot of bandwidth. HBM2e uses about half the power as GDDR6 for the same bandwidth (I don’t know about HBM3 power numbers)
