The performance is determined by the CPU and to a lesser extent the chipset. The socket has nothing to do with it.
The AMD AM4 socket will be the AMD standard at lest for the next 2 years, and all new (improved) CPU will be AM4 only.
You can look at the CPU performance charts to compare different CPU.
I am not sure that I understand your question, so please feel free to reply If I can help more.
