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

A cable from any company should work as long as it has the proper rating.

This isn’t old USB where it’s only dumb wires to wires. Modern phones negotiate the power draw with the power source, lots of intelligence built into that system, and your cable and charger need to be smart enough. You can charge a modern phone with a dumb power cable, but it will default to low power draw.
