Does Intel NUC have different performance depending on the input voltage?

I know that NUC can take different range of voltage 12V ~ 19V.

 

Does NUC have different performance depending on the input voltage?

Their response: Heat is a function of power, not voltage. The input voltage level into the system is not used directly. It's converted to lower voltages before any loads. There are some minor differences in conversion efficiency based on input voltage, but it shouldn’t really be appreciable.

Bottom line, the NUC powered with the provided 19V power supply is going to operate at the same performance levels and thermal profile as it is when powered by a boat's or car's or telescope's 12V battery.

Careful - which NUC?  Not all can use 12v.

There should be no performance differences based upon differing input voltage. Provided the source's amperage is at or above the specs, you should be good to go.

Thank you for your answer!

 

I have one more question about Power input.

Does NUC also have different heat rate depending on voltage range?

For instance, when executing same application, the more voltage input, the more hotter... (DC-DC Converter or CPU)

That I can't answer. I will ask the design team It may take a day or two to get an answer.
