I’m using s-tui to stress the CPU. It provides a convenient frontend to the stress utility.
Here’s a chart showing the CPU under full load.
The M7 results shown here were recorded with Performance Power Mode selected in the BIOS.
One oddity is the low 47W figure when the Balanced power profile is selected in KDE Plasma.
If the BIOS is changed to Balanced Power Mode, the full-load figures for KDE Plasma’s Power Saver, Balanced, and Performance profiles are 47W, 75W, and 75W respectively. In other words, with Balanced Power Mode selected in the BIOS, the machine actually uses more power with KDE Plasma’s Balanced profile than it does with the same profile when the BIOS is set to Performance Power Mode.
For completeness, with Power Saver selected in the BIOS, full-load power usage is 47W, 47W, and 65W with KDE Plasma’s Power Saver, Balanced, and Performance profiles, respectively.

I’m not an expert on power testing, but this makes the M7 look a bit less impressive to me.
I always thought mini PCs were supposed to be really efficient, especially when just doing normal desktop stuff. So seeing it use quite a bit more power than some AMD mini PCs is a bit disappointing. Maybe the performance is great, but if it’s using more electricity all the time, that has to count against it.
