and still high idle power usage (cant get mine under 15w) my nvidia / amd cards idle around 4-5w even with screen attached.. (im using a a380 in a server for video encoding/decode)
You can get it to 1w with 12th gen+ cpu with iGPU

iGPU just bypasses the dGPU. That shouldn’t be necessary.
You can also do this with Nvidia and AMD GPUs, kinda the whole way laptops work to conserve battery is to just shut off the dGPU when not in use.
It's cool and all, but changing the whole platform just to help the gpu's idle power consumption sounds like a terrible solution.
Especially when you can just buy an AMD or Nvidia GPU instead and get almost all the power savings that way.
When ARC was first announced I was pretty excited to get Intel's super low power iGPU and their GPU splitting tech (GVT-g) in a discrete card. Then they canceled all future GVT-g development and the cards crapped the bed on idle power consumption.
