Does SetNetworked* functions check if value is changed?

[superdodo12]

I was wondering if the SetNetworked* functions directly send a update packet every time they are called or if the functions check for if value changed before sending.

The wiki reccomends not using them. But it also says that they are automatically sent/received on delta.
