It doesnt always mean something new in PHD. as a physicist myself, a PHD work could go either be making something new or a complete study of a selected system or topic. Both are equally hard as making something new requires patience.

If you are asking for workload, of course PhD work is much harder, as a master is just a training from degree to PhD. Dont look down on PhD though, i've seen people in my labs repeating another cycle of their PhD or doing their masters for 4 years just to fully obtain the skills needed (local uni - research point of view) i blieve its gonna be dif with private colleges
