  • What’s thunderbolt ?

    Thunderbolt™ technology is a cable connection interface developed by Intel over the last decade. Here are three of the most important features of Thunderbolt™ technology:

    •Thunderbolt™ ports provide high bandwidth for connecting high-speed devices.

    •Thunderbolt™ cables help to ensure a quality connection between the device and a PC.

    •Thunderbolt™ accessories make it easy to expand the capabilities of your PC with docking options and external devices.


  • What’s New with Thunderbolt 4?

    Thunderbolt 4 was announced at CES 2020 and the final specification was released in July 2020.The key differences between Thunderbolt 4 and Thunderbolt 3 are support for USB4 protocol and data rates, a minimum bandwidth requirement of 32 Gbit/s for PCIe link, support for dual 4K displays, and Intel VT-d-based direct memory access protection to prevent physical DMA attacks. Another major improvement is that TB4 now supports Thunderbolt Alternate Mode USB hubs ("Multi-port Accessory Architecture"), and not just daisy chaining.The maximum bandwidth remains at 40 Gbit/s, the same as Thunderbolt 3 and four times faster than USB 3.2 Gen2x1.


  • The Benefits of Thunderbolt 4

    While all ports fulfill the basic purpose of connecting input/output devices to a PC, Thunderbolt 4 ports have several distinct advantages:

    Flexibility. Some ports power your devices. Others transfer data from devices to the PC. Still others transfer video signals from your PC to an external monitor. A Thunderbolt™ port can do all three. It delivers high-speed data transfer, outputs a video signal, and can deliver power to compatible devices (including charging a lightweight laptop) simultaneously.

    Bandwidth. Thunderbolt 4 ports have a 40Gbps (gigabits per second) bidirectional bandwidth. That means data can be moved to and from external storage quickly, and that up to six Thunderbolt devices can be connected for flexible device configurations—all powered by one port.

    Versatile connectivity. Thunderbolt 4 ports are compatible with many connection standards, including previous versions of Thunderbolt™, USB, DisplayPort, and PCle. The ports fit standard USB-C type connectors.
