Thunderbolt (previously called Light Peak) is a new peripheral-connection technology, developed by Intel with collaboration from Apple, that combines data, video, audio, and power in a single connection. Based on the PCI Express and DisplayPort architectures, Thunderbolt allows for high-speed connection of peripherals such as hard drives, RAID arrays, video-capture solutions, and network interfaces, and it can transmit high-definition video using the DisplayPort protocol. Each Thunderbolt port also provides up to 10 Watts of power to connected peripherals.
|Revision||Year Released||Super Set Of||Top Speed||Port Type|

|Thunderbolt 2||2013||Thunderbolt||20Gbps||Mini Displayport|
|Thunderbolt 3||2015||Thunderbolt 2(adapter required,)DisplayPort,PCIe 3rd Gen,USB 3.1||40Gbps(short or active cable) 20Gbps(long,passive cable)||USB-C|
Thunderbolt™ 3 brings Thunderbolt to USB-C, creating one compact port that does it all—delivering the fastest, most versatile connection to any dock, display, or data device. For the first time, one computer port connects to Thunderbolt devices, every display, and billions of USB devices. A single cable now provides more data and video bandwidth than any other cable, while also supplying power. It’s unrivaled for new uses, such as 4K video, single-cable docks with charging, external graphics, and built-in 10 GbE networking. Simply put, Thunderbolt 3 delivers the best USB-C.
Technically, the plug is the same and the only difference is that the Thunderbolt connector can carry – in addition to the classic Mini DisplayPort – a Thunderbolt signal, which is a signal PCI-Express (4 lines). Specifically, a Mini DisplayPort adapter runs on a Thunderbolt plug.
Thunderbolt 3 defines a superset of capabilities that runs on USB-C connectors and cables. In brief, Thunderbolt 3 brings Thunderbolt to USB-C. Here are the superset of features that Thunderbolt 3 provides: At 40 Gbps, Thunderbolt 3 is the fastest connection available. By comparison, native USB 3.1 operates at 10 Gbps.
Thunderbolt is an interconnect technology developed by Intel in cooperation with Apple. Thunderbolt combines PCI Express and DisplayPort into a single connection, allowing for a combination of up to six peripherals, like storage devices and monitors, to be daisy-chained together.
See what makes Thunderbolt 3 technology the most advanced USB-C available, with lightning speed in one thin, reversible compact port.
Thunderbolt technology is a revolutionary I/O technology that supports high-resolution displays and high-performance data devices through a single, compact port.
Thunderbolt is based on PCI Express, PCI Express is the high-speed architecture that’s used to connect many of the components in your Mac, such as the processor, graphics card, and hard drive. It offers a direct connection to the PCI Express bus, which is part of the reason it can offer such impressive performance.
There are many new Thunderbolt technology products in the market today. Thunderbolt 3 technology is 8x faster than USB 3.0 and provides 4x more video bandwidth than HDMI 1.41 helping you work and play more efficiently. It also enables a simple, single cable connection to displays, docks and storage, while charging the system.
