Also consider that Final Cut Pro X leverages Intel QuickSync to speed up render times

the point of the video is that these high end RTX laptops are all power limited when on batteries.

I think a better argument is Premiere runs like dogshit across the board and Resolve is pretty impressive for how new it is. Or software optimization matters more than hardware brute force power

The better argument is that no matter what NLE you use, you won't be getting any of the performance you're expecting on battery power with these high end "workstation" RTX laptops if you use them as laptops. 

I will agree the battery management in windows compared to MacOS is terrible. I am always messing around going from power saver to max performance 

The battery management isn't the problem. The problem is the actual hardware. You cannot run an RTX graphics card anywhere near peak performance on a battery. It's just not gonna happen. Nothing in software can fix something that's limited by physics. 

I mean they are trading off performance or battery life. But they could easily run RTX cards in a laptop at full power but issues like thermals and poor battery life come up. If you design it just for speed than you'll end up with a massive 12lb brick that you can barely call a laptop
