Overdraw offscreen does it impact performance?

Hello guys.
I have things happening inside my camera view and I have cached prefabs already instantiated outside of the camera view. When I need them i just move them to where they can be seen (inside the camera view).

I would like to know if having them there impacts performance due to overdraw or not? My understanding is that since they are not inside the cameras view they only take up memory that was allocated for the textures and classes that they are made of.

Here is a screenshot to give you a better understanding :

The white rectangle is the camera view. I've used the Overdraw setting to show places where it occurs.

 

No, because Unity won't render sprites outside of the camera view. You're good GPU-wise.
