Compute cycles: CPU and GPU are very very different here, so I'm not sure that logic holds. Unless you're doing work that's heavily GPU-bound and truly using the same resource (which is a non-trivial amount of jobs, but far from a majority. maybe even less than 1%?).
For the rest, it shouldn't cost much more compute than two 4K screens, and people already do that successfully. It doesn't do much to increase the latency or cost of running a million Chrome tabs or using other CPU- or IO-bound programs.
But I will agree that this all consumes more electricity, which is certainly a problem for mobile use.
- tsimionescu 3y agoI'm not sure how much of the image processing for AR passthrough, environment recognition and spatial placement of app windows is actually done on the GPU. I would expect at least some of it has to be done on the CPU. Additionally, laptops are rarely known for stellar GPUs, so I'm also expecting some need to offload GPU work to the CPU, at least in terms of power and thermal budget.
