I use an RPi3 with 7 inch touchscreen to listen to webradio all the time. Just the other day I was curious, and measured its power consumption. My laptop with Ryzen 4700u with turned off screen uses less amount of power than the Rpi with screen on (~6W for laptop vs ~7.5W for RPi). I'm really thinking about ditching my RPi's as a radio and even as pihole, as my laptop can do much more while still using close to 0% CPU.
Sure, the screen on/off comparison makes this measurement a bit unfair, but calling x86/x64 energy inefficient doesn't sound particularly correct.
- speedgoose 3y agoOne major difference that could explain the power consumption is that the 4700u uses a 7nm process, and the old RPi3 uses a 40nm process.
