Hard data?! Or a hard distraction?
This so-called "hard data" is very subjective and have too many unknown variables.
Testing setup - open bench, air w/closure, AIOs, heck, nitrogen compared to my setup.
Ambient temps - my gaming room 23-24, the reviewers room 20-22.
OS / Programs - Reviewer clean OS w/games, and monitoring tools, me, the same plus anti-virus, AutoCad, Adobe suites, Final Cut, etc.
So much more.
So, that one source "hard data" is not conclusive for everyone's setup.
But, it is a decent source for a first-look.
