I'm curious - for power consumption, considering that you can get RaspPi products for so cheaply, is a discarded laptop more or less impactful on your electrical bill than a RaspPi?
Like is the "free" laptop going to cost you more in the long-run then a nice little power-sipping ARM like a Pi5? Or do you need those extra operations-per-second that the more power-hungry x86 CPU gets you?
- krautburglar 6mo agoEverything outside of power equipment -- like HVAC, refrigerator, laundry dryer, etc -- is a rounding error on most power bills.
- Pxtl 6mo agoRight but so's the price of a Raspberry Pi. 10W running 24/7 means about 7.3 kWh/month. In my area the average kW/h costs about $0.13 CAD So a good rule of thumb is that every 10W 24/7 is about $1CAD/mo. So assuming 30W for a laptop and 6W for a pi4, that means a difference of $29/yr. Which isn't a lot but isn't a rounding error either.
- krautburglar 6mo agoLaptop/desktop wattage varies with processor and peripheral load. Unless you are pushing 10gbit and leaving the screen on 24x7, even an old box will be mostly in an idle state, with actual draw well below 30W. Even if that were not the case, paying an extra $2.50 / mo to not do ghetto fabulous bs with rpi and vlans seems like money well spent to me.
