What's Thunderbolt 3? It looks like the usual USB type-c interface on the outside, but there's a Thunderbolt 3 sign next to it.
Strictly speaking, Thunderbolt 3 is the interface while the Type-C is an interface specification.
On February 24, 2011, Intel officially launched what was billed as the "Light Peak" technology of Intel LABS, which has been known for months, and named it "Thunderbolt." The technology of Thunderbolt designed by Intel in 2009, and named as "Light Peak" (code name is Thunderbolt). The purpose of researching Thunderbolt is to substitute and unified the present number of computer performance of jagged extension interfaces, such as SCSI, SATA, USB and FireWire and PCI Express.
The second generation of Thunderbolt has been using the same interface as the Mini Display Port, which has been used in Apple’s previous MacBook Notebooks. Thunderbolt has developed into the third generation and it’s designed with a sound base for Type-C and a Type-C appearance. Why did Apple always use Thunderbolt in advance? Because the technology was designed by Apple and Intel, thus Apple has a certain right to use it which makes others think they are ahead.
Thunderbolt 3 is the most powerful interface.
Thunderbolt 3 brings with it a combination of superior speed and rich functionality. It has twice as much bandwidth as Thunderbolt 2 and sets the data transmission, video output and charging into one small interface. It is also integrated with USB-C, and while gaining the Thunderbolt speed. It is more convenient and easy to use, setting up a truly universal port.
Advantages of Thunderbolt 3
Data transmission capacity: Thunderbolt 3 is under a data transmission rate of up to 40 Gbps, twice as much as Thunderbolt 2, and eight times as much as USB 3, which can provide high-speed connections to any pedestal, display, or device. You can also connect up to six Thunderbolt devices to a single port in a Daisy chain without requiring a hub or switch. With strong data throughput, you can connect the storage device to your computer, and the screen will connect to your storage device, and everything will function as usual.
Video ability: Thunderbolt 3 has twice as much bandwidth as Thunderbolt 2, so it can support two 4K displays or a 5K display. With two Thunderbolt controllers on the new 15-inch MacBook Pro, you can send graphics to two 5K displays, which are ideal for editing high-resolution photos and video. Thunderbolt 3 can connect to all displays and monitors with DisplayPort and Mini DisplayPort in native mode, and HDMI and VGA displays can be corroborated using converters.
Power Supply ability: With Thunderbolt 3, a USB-C port can be powered bi-directional. The same port can be charged for the equipment and can be charged by other equipment. Since it can provide a current of up to 100 watts, a cable can be connected to a base or screen at the same time, as well as charging your MacBook Pro.
Downward compatibility: Thunderbolt 3 uses the technology of USB-C, which is a truly universal connection. You can connect various devices, including existing Thunderbolt 2 devices, with a converter or cable. That is to say, the commonly used USB specification or Thunderbolt 2 specification, Thunderbolt 3 is backwards compatible.
