This answers the question in the literal sense, but I'm nonetheless surprised (as a relative outsider to the world of high-speed signalling).
"just double the frequency" isn't something we're used to seeing elsewhere these days (e.g. CPU clock speeds for the last couple of decades). What are the fundamental technological advances that allow them to do so? Or in other words, what stopped from from achieving this in the previous generation?
