Power Consumption with CPU Stressed
I’m using s-tui to stress the CPU, which in turn uses the stress tool.
$ sudo apt install s-tui stress
I can stress the CPU by changing the mode from monitor to stress. Here are the results for each machine.
As the chart illustrates, the Radxa Cubie A7A’s power consumption of 9W puts it at the top end of the single-board computers. Its power consumption is less than half that of the Intel N95 and N100 machines.
Power usage figures are higher if other system components (GPU, disk etc) are also stressed. The chart reflects power consumption stressing the CPU only.
