Yes.

Also, it doesn't seem like it would be all that much more expensive for these high end GPUs to start getting x86/64 SoCs with midrange specs baked in, and these AIO GPUs could be tailor made for standalone AI and gaming applications. If it's the equivalent of a $10 bit of gear in terms of cost, they could charge an additional $100 for the feature, with a SoC optimized for the specs of the GPU - get rid of the need for an eGPU altogether and stream from the onboard host?

This is very much a “would you like some coffee with all of your cream?” situation.
