[Harry Potter] How powerful is Voldemort really?

Of course he is a very powerful wizard, but what is it that makes him in the top 0.001% rather than the top 0.1% of Wizards. I know these statistics are a little arbitrary but hopefully you see what I am getting at.

Is it just that he is extremely charismatic and intelligent? Because you rarely see him in action and other than being willing to use evil spells and be mean I don't see how he has demonstrated that he is extremely powerful.

If magic were a sport, Voldemort would be gold medalist. He can push his magical limits further than almost all wizards. An excellent example is his ability to fly without a broom - almost no other wizard can do that.

He's powerful because of both raw talent, training, and an unwillingness to recognize limits. As a child, Tom Riddle was using magic spontaneously (without understanding what it was, and before Hogwarts). When he took his OWLs, he got Outstanding in every subject. And he has no compunctions about using dark magic and rituals, which means his options are wider.

Going back to the sports analogy, Voldemort is like a world-class boxer. Not only is he extremely strong and fast, but he also has training so that he can hit in ways that others simply can't. It's talent and training.

The biggest example of his power is probably the horcrux ritual, since it's complex and dangerous simply to split one's soul even once, and he managed to do it seven times.
