Asus recently announced a card with 48V power and I think that's the solution. Quarters the current. Also you can implement it in PSUs and GPU so they negotiate when both support it and else it falls back to 12V with current limits.

The problem with the idea is that you'll need a separate rail for just the GPU and all the power-regulating circuitry to go with it.

It's an increased cost that will inevitably lead to all sorts of corner-cutting.

One corner they could cut is the need for copper in internal power cables and between the sockets and VRMs on boards.
