Thunderbolt 3 began its shipping in the last quarter of the year 2015. Thunderbolt 3 uses a different conductor than the traditional Thunderbolt or Thunderbolt 2. At the speed of 40 GB/s, Thunderbolt 3 tends to double its so called theoretical potential for speed when subjected to comparison with Thunderbolt 2 or at the speed of 20 GB/s. Thunderbolt 3 at the speed of 40 GB/s, is quadruple than the speed of traditional Thunderbolt and quadruple to the speed of the USB 3.1 ports as well. Also, users will be able to use Thunderbolt 3 as Display Ports or USB 3.1-C port. It will also be able to offer 15 watts of power to the devices. In other words, you will be able to charge the docks, cell phones and other USB and Thunderbolt devices with a Thunderbolt 3 port.
It will also offer a multitude of connectors to keep the prices low from the various needs of various users. The first Thunderbolt 3 cable choice is the USB C compatible copper cable which has the transfer rates of up to 20 GB/s. The second Thunderbolt 3 cable choice can be used as a USB C Compatible copper cable which had the transfer rate of 40 GB/s. The third has the USB C compatible optical cable capable of transferring at the speed of 40 GB/s. Thunderbolt 3 can also be used with the older versions of Thunderbolt cables and devices along with the use of Thunderbolt 3 and its adapter. Besides this, it will also be capable of supporting external graphics, dual 4K video support, 10GB/s Ethernet, and single cable docking with charging. Thunderbolt 3 or Thunderbolt Networking acts as a bridge between small workgroups and makes PC migration easy.
Thunderbolt 2 versus USB 3.1
Of course, Thunderbolt 2 wins the race. The latter runs more at the speed of 10 GB/s, USB 3.0 runs at 5 GB/s. PrimeCables thunderbolt cables operate at 20 GB/s. However, it is expensive and USB is omnipresent, to be put simply. No one uses Thunderbolt as an alternative to USB.
The biggest benefit of using Thunderbolt is the volume of data throughput available to the user. It has the maximum speed of 10 GB/s, the maximum speed of Thunderbolt 2 is 20 GB/s, and the maximum speed of Thunderbolt 3 is 40 GB/s when compared to 500 MB/s for Firewire 800, 5 GB/s for USB 3.0 and 10 GB/s for USB 3.1. Thunderbolt tends to transfer isochronously which is ideal for audio and video production.
