This is AMD's problem. They have nothing new in their socket designs, CPU performance is up there. However, they are on such old memory and storage controllers that they are bottlenecking themselves. Their FM2 platform is about the only one on an updated socket, and actually have better and newer controllers. Intel on the other hand, has changed sockets so many times, but it makes it easy for them to make new controllers. Zen is on a whole new socket, so we should see these numbers rise up.
