    A raspberry pi is not as efficient as people are claiming. They need up to 25W PSU for a reason. Laptops can idle lower than that certainly. Something like a MacBook Air M1 would idle in single digit territory, as would any netbook basically ever made. Only really high performance or older laptops have idle power draw issues since battery life is a major selling point of a laptop. Said laptop is probably also faster than a raspberry pi. The people building Pi clusters are really not doing themselves any favors with power efficiency.

      Nah no way does the average ewaste tier laptop use less power than a raspberry pi for any given task. The power consumption floor for a laptop may be lower than the rpi ceiling but that’s not a fair comparison

        Benchmark it and tell me. The truth is that most RPis are made using older process nodes to reduce costs. Laptops are often made using the best avaliable process node and core design. A modern raspberry pi 5 uses a 16nm processor with Cortex-A76 design from 2018. A laptop in 2015 would be using 14nm Broadwell processors from Intel. This was a time when 15W U series processors were gaining popularity, so sustained load power consumption is quite low. A 2015 laptop is 10 years old, and wouldn’t run Windows 11, so will be ewaste this year. Same with a lot of 8 year old machines actually.
