Raspberry Pi Power Consumption Comparison

Raspberry pi 3a the raspberry pi 3 model a is the latest product in the raspberry pi a format weighing in at just 29g and boasting the same specs as a raspberry pi 3b.
Raspberry pi power consumption comparison. We carefully optimized the power input circuitry to reduce power consumption and increase stability. A 64 bit quad core processor running at 1 4 ghz dual band 2 4 ghz and 5 ghz wireless lan and bluetooth 4 2 ble. For starters the raspberry pi 3 model b board uses 1 5 watts when idle and up to 6 7 watts when a monitor. Compare raspberry pi 4 vs raspberry pi 3 a vs raspberry pi 3 b vs raspberry pi 3 vs raspberry pi 2 vs raspberry pi zero vs raspberry pi.
We cut the power consumption of our boards in half as compared to the raspberry pi 3. The raspberry pi zero uses about the same amount of power as the a and at least 50 less power than any other pi b 2 b 3 b. I use the powerjive usb power meter for older pis with micro usb power inputs or the satechi usb c power meter for the pi 4 and newer to measure power consumption with the dramble and individual raspberry pis in all cases with nothing plugged into usb unless otherwise noted. Where as raspberry pi 3 needs a 5 5v power supply to maintain stable 5v rails during cpuburn a53 aml s905x cc will work without issue even with 4 1v power supply.
Raspberry pi 4 b version with 8gb memory and layout of power supply components updated. I will be adding power consumption statistics to this page as time goes on.
