/3/ - 3DCG

I have a question about eevee, I like the renders i'm getting but there's always some weird noise in the reflections/light diffuse, I realize eevee is most suited for animation and I'm definitely going to use cycles for still images, but that noise still annoys me.
How do I fix it? There's some secret setting I didn't turn on? Do I need to render in a higher resolution and then re scale it? I've tried to up the samples, but without any results.
I've made a comparison render showing what I'm talking about.
I've set up everything in eevee first and then switched to cycles and pressed F12 right way
