Graphene is wickedly conductive, which is important. A graphene transistor was clocked at 427 GHz. Not to get all Doc Brown (http://www.youtube.com/watch?v=mjCRUvX2D0E) on it—427 GHZ!—but that’s insane in the membrane (http://www.dailymotion.com/video/xhu0s_cypress-hill-insane-in-the-membrane_music) (i.e., insane in the brain). An 11-inch MacBook comes with a stock processor running at 1.3 GHz. So a graphene-based processor, in theory, could run 300 times that. Zoom-zoom, know what I’m sayin’?
Until now, graphene had this … issue. You couldn’t turn it off. And if you know anything about transistors, you know that turning on and off is sort of a transistor’s raison goddamn d’etre. So while graphene is super-fresh and all that, if it can’t turn on and off, the question of its efficacy is moot (http://www.maniacworld.com/question-is-moot.html). But aforementioned scientists have been able to come up with an entirely different way of getting graphene to work in a transistor. The result is “a system that dramatically outperforms silicon,” says the article. “[The researchers] say the performance is ‘several orders of magnitude higher than for any reported or even projected scaled circuits.’”
