Intel said the first Thunderbolt 2 products would be available by the end of the year, and it wasn't lying: Asus just announced the world's first Thunderbolt 2-equipped motherboard, the straightforwardly named Z87-Deluxe/Quad.Why is that a big deal, you ask? Simple: The first generation of the Thunderbolt interface technology hums along at 10Gbps, more than double the 5Gbps that USB 3.0 is capable of. Thunderbolt 2 screams at a face-melting 20Gbps.
