The Thunderbolt cable is specced for 10W, which is more than existing USB standards (1.5A @5V for USB3 "Battery Charging Specification", previously 500~900mA @5V, leading many — including Apple — to perform proprietary power negotiation to allow sending >~10W to their devices).
But it is much less than the more recent USB Power Delivery spec (which I guess is the subject of the article), which allows up to 5A @20V
