Power
Idle power draw (at wall): 1.8 W (See note)
Maximum simulated power draw (stress-ng --matrix 0): 9.7 W
During Geekbench multicore benchmark: 7.9 W
During top500 HPL benchmark: 11 W (2.75 Gflops/W)
- margalabargala 2y agoHuh. Maybe I had a bad power supply, then. Interesting. This is compellingly saying that I was too hasty in assuming the low voltage warnings were from the 18W supply topping out. Thank you for this.
- abswest 2y agoSeen same power warnings, when powered by RP4 5V/3A. Had to use 5.1V power supply to get rid of them.
- fostware 2y agoIt's been that way since the RP3 - heavy load resulting in rainbow square. Use the official power supply labelled 5.1v and the square disappears
- rerdavies 2y agoMaybe it's a spiky 9.7w. :-/
- lazide 2y agoA very real problem. Also power supply/chip tolerances and a little extra gunk on a pin somewhere can line up unfavorably. Personally, I had tons of power issues due to underspec cables with a Pi4. Irritating.
