The Dell is absolutely not outperforming the RPi on power consumption. I run multiple internal- and external- facing servers (eg multiple static and Java-based Web servers, SMTP, DNS, NTP, etc) and the total power usage is generally much less than 50Wh/day.
I can throw my Internet connection router and FTTC box on as discretionary load but that's another ~300Wh/day; it is quite staggering how relatively efficient the RPi is, compared to presumably similar or lower processing requirements in the other two boxes!

(You can only see the RPi's power consumption when the networking gear is pushed back onto mains.)
- kutkloon7 9y agoTrue. I was thinking of performance, but you're right: power efficiency is a measure as well, and the raspberry pi is very power efficient.
- DamonHD 9y agoAnd idle power matters: a typical server in this kind of use is going to spend much of its time doing very little at all. (Except in my case fending off attempts to SPAM me or other malicious traffic!) It helps that I can set the RPi's clock to fall back a long way unless the CPU is busy.
