    If the amount of efforts spent on making hybrid laptops work properly was instead spent on enabling dGPUs to scale down its power usage to the level of iGPUs we would've had a proper solution by now that saves power, complexity on both hardware and software, and space on the CPU that can be used instead for more cache or more cores, or simply just less heat.

          I wonder how AMD will handle it when zen4 all have igpu chips. Will it route desktop apu accelerated output to the dgpu display driver? In which case performance impact doesnt matter much but it could matter on terms of desktop responsiveness. Probably negligible though.

            I'm sorry but I don't remember. A dev wrote something about it but I can't find it either.
