请帮忙确认MIMX8MM5CVTKZAA在功耗相当的情况下,比IMX8MM6DVTLZAA芯片表面温度高很多的原因是什么?

Please note that MIMX8MM5CVTKZAA is industrial part and MIMX8MM6DVTLZAA is consumer one. It may take some small difference in temperature.

Also please note that maximal frequency for MIMX8MM5CVTKZAA is 1.6 GHz and 1.8 GHz for MIMX8MM6DVTLZAA. So there may be some difference at low frequency.
