Graphene is wickedly conductive, which is important. A graphene transistor was clocked at 427 GHz. Not to get all

on it—427 GHZ!—but that’s

insane in the membrane

(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. 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.’”
