This is a great video that shows the thermal comparison between the 14’” and 16” M1 Pro starting at 9:05

This was a really interesting test and the results are impressive.

My only nitpick with the video is the battery comparison showing the % used. Of course the 16” is going to have a higher battery percentage left after each test, it has a larger starting battery (70Wh vs 100Wh).

So when the final tests are done, comparing 51% left on the 14” vs 67% left on the 16” is one thing (and definitely important for overall usage time), but it’s important to also note that the total amount of power used (49% of 70Wh on the 14, 33% of 100Wh on the 16) was roughly the same (34Wh vs 33Wh).

This means there really isn’t any difference in battery efficiency between the two sizes, just the amount of total juice available, and it should probably at least be mentioned in the results that the 14 is about equal to the 16 in that regard.
