How strong/quick could a robot with human dimensions be compared to a human? Is it limited by hydraulics?

I'm picturing things humans do well, and how a human sized robot could do it. How strong can a robot with human dimensions be in theory?

The largest groups of muscles that control as single joint are your quads and hamstrings, which do nothing but bend your knee. We can make machines the size of a person's thigh that can generate more force than a knee, and the same goes for other joints. The biggest problems with building humanoid robots are power storage and balance.
