content: My guess is they're using some of the older designs from single core CPUs that were amazing but melted the computer when used. Because the carbon can take the heat, no pun intended, they can run these designs with less of that fear. On top of that they are using very small scale, I'm guess, because the wording bring the idea of x1000 fast than modern CPU (like i7), but sounds more like x1000 than a CPU with the very low amount of transistors. (and from what I read they don't mention what kind of architecture they're using)
