What’s the difference between different brands’ fast charging USB cables?

Question

I have a OnePlus phone and I know that to fast charge it I need to use a special USB cable.

But Samsung phones, for example, also have their own fast charging cables.

So why can’t those phones fast charge with the other manufacturer’s cables if the cable is able to transfer enough power anyway?

At the end of the day the cables are simply transferring electricity, and the more watts the faster it should charge, no? At least that’s the way I see it

Any USB C cable used for 60/100 watt charging purposes must be electrically marked as such. Without such a marker the limit will be lower than that.
