RDP is probably more intelligent than most people are aware.

Try remoting into a machine over RDP and playing a youtube video occupying a large portion of the screen. You may be surprised to find that it plays nearly perfectly, even over non-ideal network conditions (wifi). Try this same exercise with VNC and you will experience a frame maybe once every other second.

I am not sure exactly the heuristics involved, but RDP is certainly switching between modes of operation based on what kind of visual information is on the screen.

RDP also works more reliably over mobile connections than VNC, in my experience
