Poor drivers. The same reason why the discrete GPU pulls around 20W just for being on with an external screen, even if the screen is black. Apparently not an issue:

    * in clamshell mode;
    * on Windows via BootCamp.
According to some reports in the MacRumours forum [0] this is fixed in Monterey.

Edit: Not quite a fix. Apparently they introduced a Low Power Mode that helps bring wattage and temps down by essentially preemptively throttling CPU and GPU or something like that.

Not really a fix then. That may prevent hurting your machine but it’s still not running at optimal performance.

Indeed. I disable turbo boost on my 16". It hurts peak performance but runs (slightly) cooler and quieter, and sustains for longer. This reads all kinds of wrong.
