Is intelligence directly related towards skill in chess?

I think to be 2400+ you must be very smart and photographic memory at least. GMs remember by heart all of their games. If you watch super-GM tournament, they walk to other board and when come back they know what move their opponent made and write it on scoresheet. I don't think I will ever be able to do that.
Have you ever been to a tournament? This is actually pretty easy. Almost everyone can do this. Because the games are so long it's easy to remember the position.
Yes this is nothing. Something: in a simul, GM's could typically replay all their games from memory.
In January 1922, Frank Marshall played 155 opponents on Montreal. He won 126, lost 8, and drew 21 (88%) after 7 hours of play. A week later, he was able to replay 153 of the games from memory. What bothered him was forgetting the other two games. He thought he was losing his memory.
