At first: Stop posting Tomshardware! They just bulk repost ad-enriched low quality clickbait content without validating anything (cough 9700X3D). Just post the original video.
As the video creator said in it's disclaimer, the test is probably not accurate:
- I'm having serious doubts about the test setup. The laptops are all on a carpet directly facing a wall. There is a 0% chance that this is using proper air circulation and this will likely effect heat dissipation.
- Some tests (e.g. Video editing, Battery life) are extremly hardware dependent and shouldn't be used in a OS comparison.
