SBC Power Consumption Rankings

Compare measured idle and full-load power draw across Single Board Computers

74 boards tested · readings from 0.6 to 13.7 (Idle (W))

Some earlier test runs recorded load power but not idle, so those boards appear only in the load and peak rankings.

Frequently Asked Questions

Which single board computer uses the least power at idle?

The Arduino UNO Q 2GB currently has the lowest reading in our Power Consumption ranking at 0.6 (Idle (W)), measured on real hardware with our standardised test setup.

How much power does a single board computer use at idle?

Across the 74 boards we have tested, Power Consumption results range from 0.6 to 13.7 (Idle (W)), with a median of 2.2. Anything below the median puts a board in the lower half of the boards we have tested.

About SBC Power Consumption Rankings testing

We measure power at the board's power input with a TC66 USB power meter, sampling twice a second, and subtract anything we had to plug in for testing. Idle is the average over 20 seconds once the board has settled for 30 seconds with its default CPU governor, which is the number that matters for anything left running around the clock. Load is the average over five minutes of stress-ng hammering every core with CPU and matrix work under the performance governor. Linpack peak and Ollama peak are the highest readings we saw during those two benchmarks, which is a good guide to the power supply a board really needs. Lower is better for every figure, but remember that a board drawing very little at load is often simply a slow one: our Linpack GFLOPS per watt and Ollama tokens per watt rankings show efficiency.
