The DGX Spark apparently consumes up to ~150W while being able to run many models at decent speeds. I think really good efficiency is possible right now, but the GPU makers don't want to make their consumer GPUs too good for AI - if the cards were more efficient, it'd be much easier to run multiple - while data center ones have a bunch of additional power overheads.
