They don’t get their absurd profit margins by cannibalising their data centre chips.

This is like Intel and their refusal to support ECC memory; when AMD does on nearly all Ryzens.

Note: your laptop is probably using a 64-bit memory bus for system RAM. For GPUs, the 4090 is 384-bit. That takes up a lot more die area for the bus and memory controller.

But GP's laptop with 96GB of unified memory would be a M2 Max Macbook or better. The M2 Max has a 4 x 128-bit memory bus (410GB/s) and the M2 Ultra is 8 x 128bit (819GB/s), versus a 4090 at 1008GB/s. But see here for caveats about Mac bandwidth: https://news.ycombinator.com/item?id=38811290
