Ok, there is no change.

But how much die real estate for 8GB/16GB of sram in such fantasy world?

[wtallis]

Going based on AMD's first generation V-Cache (TSMC 7nm), you could get 1GB of SRAM onto a die slightly larger than a top of the line NVIDIA GPU. 2GB would be too large to fab as a single die. Or you could spend several million to get a Cerebras Wafer Scale Engine 2 with 40GB of SRAM in aggregate and a ton of AI compute power all on one wafer.

ok.

Then 8GB sram with a modern CPU, Zen4 for instance, is a die of ~ 9 top-of-the-line GPUs dies.

And now, with 3D? ... mmmmmh...

What is the size of the apple M2 die already?
