Lots, apparently. 

Using a chip produced by German silicon manufacturer Infineon, engineers have created a robot capable of analysing a Rubik's Cube and solving it in just over 0.6 seconds. 

For context that involved first observing the state of the cube, analysing to find a solution, and then operating the 21 moves required - in less than a second. 

So what has this all got to do with self-driving cars? It's all about reaction time here - and the implications that has on safety. In a braking scenario, for example, the reaction and actuation time for a self-driving car will have to be as good as a human's reflexes. With technologies like this, machines will in fact be vastly superior.
