Thunderbolt 3 can also move data twice as fast as the previous version, with speeds now up to 40gbps. It'll support up to two external 4k monitors or one 5k monitor. Thunderbolt 3 cables won't work with USB Type-C ports already in the wild, but we could start seeing support for it in computers as early as 2016.
USB Type-C is being hailed as a game-changer in technology circles. It's slim and a little wider than Lightning ports currently used in iPhones. Its ability to support things like charging, fast data transfers, and multiple screens has people hoping it will replace all other connectors.
