HDMI comprises several standards. The HDMI 2.1 standard is the most advanced and therefore the "fastest". Whether it's for video, TV or just playing around... So, this cable is perfect for the PS5 but it hasn't been "optimised" for it. (Because who cares about the PS5?).
To find out the answer to this kind of question, look at 1. the product requirements (PS5) and 2. the definition of standards (Wikipedia, for example)
https://fr.wikipedia.org/wiki... .
Otherwise, 1. spend most of your time playing around :-) or 2. ask the people who spend their time looking for answers...
