The M3 boasts an octa core processor as we all know it but somehow the experience on Linux is not as smooth. I looked a little into the temperature and the CPU usage and came to a little conclusion.
With a 14mmx14mmx9mm heat sink, the temperature idles at 65 degrees Celsius. Which is the load temperature for many desktop processors properly cooled.
The CPU keep around 1 of the 8 cores at near 100% while the others at 0-30%. The core under load switches every few seconds probably to balance the thermal output.
I can never squeeze enough power from the 8 cores since they are basically all at sleep.
I got a PC fan and put it on top of the heat sink and the idle temperature dropped to 45 degrees Celsius and temperature under load to 55. Then around 2 of the cores ran at 70-100% while the others are at rest. But mostly still only 1 core ran at 100%.
I think due the the fact that the CPU is designed for mobile devices and the lacking of cooling on the M3, we are missing out on a lot of the power offered by A83t.
