Fake news. Modern RPis need up to 25W PSU. Even old laptops could idle lower than that, as otherwise they wouldn’t be able to get significant battery life. Turning off the screen will also really lower their power consumption.
You’re comparing a laptop at idle to the power supply for a pi that needs to power it at full load plus overhead and inefficiencies. That’s like comparing apples to an orange tree.
I mean sure. If you want to compare actual efficiency then performance per watt is the metric. Here a laptop would easily win as it has higher performance for similar power. The TDP of a U class processor is only 15W normally. It would obviously help to disable things like Turbo Boost as well. Said laptop having more performance wouldn’t need to stay at high power states for as long as the Pi either as it takes less time to process requests. Returning back to idle faster is a big advantage.
