Those are for single player. The problem most people have is that they play single player just fine and then switch to multiplayer and have performance problems. This is because the multiplayer is a lot more cpu dependent than the single player.
There are no benchmark results as far as I am aware of for multiplayer as getting consistent results is difficult because there is too much variation.
maybe when the mantle update is released it will help with the problem due to the cpu not having to do as much work:)
