Except that all the CPUs just have GPUs built in anyway, and they're almost guaranteed to be more power efficient than keeping an entire second board powered, even in very low idle states, due to having integrated power regulation circuitry and not needing to keep an interconnect/bus powered.

Yes, that doesn't conflict with it in any way. By then the "big gpu" will just be integrated into the cpu.
