Most of the higher idle in dGPUs are due to the dedicated VRAM. Everything that is responsible for transferring data and traffic needs to have a high-on state, so it has to be the last one that can be put to idle.Correct me if I'm wrong, but doesn't the use of a dGPU in a laptop result in a huge idle or near idle power consumption issue? at least when the dGPU is NOT disabled, what I mean is, imagine if I want to use the dGPU lightly for some reason (codec support, etc), isn't the dGPU going to consume a lot more power than the iGPU doing the same thing?
But for the best performance, there's no alternative to having things dedicated. Because sharing causes contention, which reduces performance, even if you had same bandwidth and capacity.
