You can’t say ‘Are these the same meaning?’! You should ask: Do these have the same meaning? Do these mean the same thing? The answer is always ‘no’. There will always be, at least, some slight difference. If you really want to know what the difference is, or whether it is big enough to worry about, you can ask that.

It's. Similar meaning for two sentences But with even was like I was surprised she is more intelligent than....

I agree with Pip, EVEN MORE, implies that her brother is intelligent, but she is EVEN MORE intelligent. If the brother were not intelligent, it would make more sense to just say, 'She is more intelligent than her brother.' In this case, it's possible that neither one of them are very intelligent. A turtle is faster than a snail. (neither of them are fast) A cheetah is even faster than a leopard. (both are fast, but the cheetah is faster)

Yes they mean the same thing: but saying ‘even more’ makes it sound more shocking and interesting than just ‘more’. I’m more shocked than you: I’m surprised (more than you) I’m even more shocked than you: I’m really really surprised (you’re surprised but I am more!) This has more emphasis and sounds more dramatic.
