I think in terms of actually doing stuff AMD is close in terms of power draw (W/performance) but it’s the little things like going to sleep and while completely idle that the entire MacBook draws so little power that needs to catch up – and that’s not entirely on the processor.
I think anyone who’s tried one of these games or is the parent of someone who’s tried one of these games figures out this loophole (or alternatively , predatory practice) pretty quickly.
