A lot! I mean at this level you have enough Kanji knowledge to be at N2 level(only my Kanji level is at N2 though haha).
That being said, reading Kanji is different from reading overall. You will still be very slow at reading but you will be able to recognize a lot of characters. In other words, you won’t spend 3 hours trying to read a page.
The greatest benefit I would say is being able to discover new Kanji. What I mean by that is when you discover a new Kanji and you don’t know the reading you can actually find it. You know a lot about radicals, you know a lot of Kanji and you can play around until you “decrypt” the Kanji that you don’t know. At least, you will be able to pull that off most of the time.
It also becomes easier to learn more about grammar because you can focus on the actual grammar “process” instead of worrying about what the characters even mean. You won’t be scared of facing new Kanji, actually the opposite. It will become like a challenge to find that goddamn Kanji haha.
TL;DR You can start enjoying native material but you are still far from fluency.
