Thunderbolt™ Technology: The Fastest, Simplest and Most Reliable USB-C Connection1
What Is Thunderbolt Technology?
Thunderbolt technology is a universal cable connectivity solution that offers 40 gigabits per second (Gbps) bandwidth for high-speed data and video transfer, while also charging your laptop3 over a single cable. It uses the same Type-C connector as other USB Type-C (USB-C) ports.
However, Thunderbolt 4 technology is much more than a USB-C connector. Thunderbolt brand certification mandates higher minimum performance and capabilities for cables, PCs, and accessories for greater reliability across devices and operating systems. As the most complete and highest standard of USB-C connections available on the market, Thunderbolt 4 technology is backwards compatible with its prior generation as well as millions of USB 3 and USB4 products.
Thunderbolt Advantages
Thunderbolt Technology vs Other USB-C Connections
Despite Thunderbolt 4 products using the same USB Type-C connector—recognizable by its oval shape—Thunderbolt 4 brand certification requires higher minimum standards for power, data, and video, with constant 40 Gbps bandwidth in each direction and supports PCI Express (PCIe) connectivity for fast data transfer speed.
Other USB-C cables, devices, and ports may be limited to a variable range of data speeds, with no guarantee of display quality nor simultaneous laptop charging. PCIe support is unavailable with USB 3 and optional on USB4. The Thunderbolt logo is a simple, sure-fire indicator of what a connection between devices can do.

Thunderbolt Technology Benefits
As part of Thunderbolt brand certification, mandatory testing ensures broad compatibility across Mac, Windows, Chrome, or Linux. It also ensures interoperability of computers, cables, and accessories from different brands, so your devices work well together regardless of the OS or hardware manufacturer.
Thunderbolt 4 technology is backwards compatible with its prior generation as well as millions of USB 3 and USB4 products. In 2019, Intel contributed the Thunderbolt protocol specification to the USB controlling consortium, the USB Implementers Forum (USB-IF). The royalty-free use of the Thunderbolt protocol aided in the development of USB4, the next-generation USB protocol. The convergence of the underlying Thunderbolt and USB protocols further increased compatibility among USB-C-based products, simplifying how people connect their devices. However, when devices with varying ports are connected, performance capabilities will only support the lowest level of the standard in that connection.
Thunderbolt 4 technology provides a consistent total bandwidth of 40 gigabits per second in each direction. This bandwidth is dynamically allocated between data and video for all devices on a single connection. Compared to the variable speeds of USB 3.2 and USB4, the high standard set by the Thunderbolt 4 interface delivers peak data transfer speeds—or maximum video display quality—to support productivity, gaming, and content creation.
Thunderbolt Technology Use Cases
Docking Stations
Connect multiple devices to a Thunderbolt dock or hub that can be plugged into a computer with Thunderbolt ports, consolidating all accessories into a single connection. Set up once and be hassle-free. Additionally, the entire accessory setting could be shared with other users by simply switching a single cable to the other user’s notebook.
Display Connectivity
Enjoy stunning visuals on larger monitors with built-in Thunderbolt ports or easily connect any monitor to a full-featured Thunderbolt dock. The 40 Gbps high-bandwidth connection supports premium visual quality with maximum resolution, refresh rate, and color accuracy without adding extra cables to your workspace.
External Storage
The high bandwidth Thunderbolt 4 interface allows end users to connect their computer to external storage that uses PCIe-based drives. This capability delivers the highest performance and makes it possible to game or create directly from an external drive, freeing up valuable storage space on the computer.
External Graphics
Add more graphics horsepower by connecting your laptop with an external high-end desktop GPU. Gamers can play at recommended visual settings and higher frame rates, even on thin, light notebooks. Creators can significantly reduce rendering and export times, boosting their productivity and output.
Streaming
Victory or defeat is determined in a fraction of a second. Record precious frames for your highlight reels. Thunderbolt audio/video capture cards offer the ability to capture your gameplay at up to 240 FPS in full HD for the smoothest motion and crispest details. That high quality is totally unmatchable!
Daisy Chain / Hub
Connect multiple Thunderbolt devices together in a daisy chain. Data and video signals can flow from the computer down the chain into five accessories. Thunderbolt 4 technology also introduced a new capability allowing accessories to provide up to four Thunderbolt 4 ports so users can connect more Thunderbolt devices into a single hub or dock.
