  What is Thunderbolt technology?
  Thunderbolt (also known as "Thunderbolt", translated as "Thunderbolt" by Apple in China) is a connector standard published by Intel. It is intended to be used as a universal bus between computers and other devices. The first and second generation interfaces are integrated with Mini DisplayPort, and the newer third generation has been combined with USB Type-C and can provide power.
  In the early days, it was independently developed by Intel and used optical fiber transmission; later, at a technology exhibition, Apple saw the prototype of early optical fiber transmission and took the initiative to express interest in Intel and gave development suggestions, resulting in the official release of the first generation from optical fiber to copper wire and Apple's Mini DisplayPort shape.
  The third generation uses the USB Type-C interface instead. Due to its two-in-one integration, it can transmit data at 40 Gbit/s in both directions (40 Gbit/s + 40 Gbit/s, especially for external high-speed networks), can directly connect compatible Mini DisplayPort devices to the Thunderbolt interface to transmit video and sound signals, and can also connect to Apple Thunderbolt Display to directly output video, sound and data at the same time, without the need to use multiple cables as traditionally.

  Introduction to Thunderbolt Technology 4
  Intel has revealed new details about Thunderbolt™ 4, the next-generation universal cable connection solution, which provides higher mini-mum performance requirements, expanded functionality and complies with the USB4 specification. For the first time, Thunderbolt 4 will provide docking stations with up to four Thunderbolt ports and universal cables up to 2 meters long. Intel's upcoming mobile PC processor, codenamed "Tiger Lake", will be the first processor to integrate Thunderbolt 4. Intel also announced the Thunderbolt 4 controller 8000 series, which is compatible with hundreds of millions of existing Thunderbolt 3 PCs and accessories. Thunderbolt 4 developer kits and certification tests are now available.
  As Intel's latest generation cable technology, the Thunderbolt 4 protocol offers significant advantages over other USB-C solutions. It offers higher performance, a range of expandable features, and is fully compatible with all Type-C solutions. Thunderbolt 4 ports are available on many modern computers and are compatible with Windows, Mac, Linux, and Chrome OS. Intel Evo laptops 5 6 and laptops supporting the Intel® vPro® 7 platform all come with at least one Thunderbolt 4 port.

  Thunderbolt products offer a consistent set of industry-leading features that connect computers to data, video, and power with just one USB Type-C port. Connect to a powerful Thunderbolt dock, display, fast storage, or any USB accessory for a clutter-free workspace. To ensure a consistent, optimal experience across a variety of product types and manufacturers, and ease of use, Intel works closely with the computer, accessory, and cable partner ecosystem to adopt mandatory certification for all Thunderbolt products. “We expect Thunderbolt 4 products to be a turning point for accessory manufacturers that rely on PCs and Macs to deliver a consistent user experience with a set of industry-leading product features.
Thunderbolt4 technology
  While Thunderbolt 4 products use the same USB Type-C connector (identifiable by its oval shape), Thunderbolt 4 branding requires higher mini-mum standards for power, data, and video, with a constant 40 Gbps bandwidth in each direction and support for PCI Express (PCIe) connections for faster data transfer speeds.
  Other USB-C cables, devices, and ports may have a limited range of variable data transfer speeds, and may not guarantee display quality or charge a laptop at the same time. USB 3 does not support PCIe, and USB4 has the option to support PCIe. The Thunderbolt logo is a simple, reliable indicator of performance between devices.
