I did some temperature tests on a NXP MCIMX6G2AVM07AA SoC (automotive grades, 696MHz). It is running a stress test application After 20 minutes, on table, it is reaching 71 degrees C.
I also ran this test on a MCIMX6G2CVM05AA (Commercial grades 528MHz). It only reached 45 degrees. Of course it is a lower frequency but running the stress test on the MCIMX6G2AVM07AA in low power mode (198MHz) made the temperature reached 67 degrees C.


I was wondering why there is so much differencies in terms of temperature between both SoCs. Why the automotive one is heating much more than the commercial one even with a lower frequency?


Thanking you by advance,
