Let me start with your last point because it’s where you’ve misread the original comment and why none of your following arguments seem to make sense to onlookers.

They have a MacBook Pro with an M4, not an M4 Pro. That is a wildly different class of SoC from the 395. Unless the 395 is also capable of running in fanless devices too without issue.

For your first point, yes it does matter if the discussion is about objectively trying to understand why things are faster or not. Subjective opinions are fine, but they belong elsewhere. My grandma finds her Intel celeron fast enough for her work, I’m not getting into an argument with her over whether an i9 is faster for the same reason.

Your second point is equally as subjective, and out of place in a discussion about objectively trying to understand what makes the performance difference.
