As part of Thunderbolt™ certification, mandatory testing ensures broad compatibility across Mac*, Windows*, or Chrome* OS, and interoperability of computers, cables, and accessories from different brands, so you can be confident that your devices work well together regardless of the OS or hardware manufacturer.
A Single Port. A Universe of Possibilities.
What is Thunderbolt™ Technology?
Thunderbolt™ 4, a CES®* 2022 Best of Innovation award winner1 is a truly universal port that connects your PC to any dock, display, and data device while charging your laptop, all through one flippable, reversible cable. Its consistent 40 Gigabits per second (Gbps) high-bandwidth connection supports multiple monitors with premium resolution, refresh rate, and color, while still having sufficient bandwidth for your data needs.
Compared to other USB Type-C ports, Thunderbolt™ ports offer top-of-the-line simplicity, reliability, and performance for immersive creation, gaming, and productivity. Mandatory testing and certification for all Thunderbolt™ 4 enabled computers, accessories, and cables offers the most reliable connectivity, allowing you to mix and match accessories across brands. Thunderbolt™ 4 technology is compatible with prior generations as well as millions of USB 3 and USB4 products.
Thunderbolt™ Advantages
Same Shape, Different Capabilities
USB Type-C refers to the shape of Thunderbolt™ 3, Thunderbolt™ 4, and USB-C ports, but each is vastly different because of their capabilities. One Thunderbolt™ port can replace all other USB-C ports on a system for the simplest, most reliable, and fastest connectivity2 for video, data, and power.
Simplicity, Reliability, and Performance Distinguish Thunderbolt™ as the Best USB-C
A single Thunderbolt™ port enables high-speed data transfer, video output, and power delivery to compatible devices over one cable, including charging a laptop3.
Unlike other USB Type-C ports, where the bandwidth may be limited, Thunderbolt™ ports always guarantee 40 Gbps total bandwidth dynamically allocated for video and data. Thunderbolt™ is so fast you can transfer a 5 GB file in about a second over the cable.
Enjoy low-latency gaming, immersive creation, and simplified productivity with Thunderbolt™ technology that supports multiple premium monitors of any type4, such as two FHD 240Hz or 4K color-accurate monitors.
Thunderbolt™ 4 certification requires at least one Thunderbolt port on the computer to support laptop charging3, unlike laptops featuring other USB-C ports that don’t guarantee system charging. Additionally, all Thunderbolt™ 3 and 4 ports provide 15W power to Thunderbolt accessories or to charge companion devices like cell phones.

FAQs
How can I check if my system has Thunderbolt™ ports?
Check out which type of ports your system has by:
- Looking for the Thunderbolt™ icon on devices (next to the USB-C port).
- Checking the product’s I/O specification online to see if it lists Thunderbolt™ ports.
- Downloading Intel® Driver & Support Assistant (Intel® DSA) to detect what ports you have on your PC.
Do I need to install Thunderbolt™ software or drivers?
No. You don’t need to install any software or drivers to make things work. Connect your computer with any Thunderbolt™ accessory, and they simply work together.
What PCs have Thunderbolt™ ports?
- Thunderbolt™ 4 technology became integrated in the CPU starting with 11th Gen Intel® Core™ processors. Today, approximately 90% of 11th gen Intel Core processor-based laptops have Thunderbolt™ ports.
- At least one Thunderbolt™ 4 port is required on all Intel® Evo™ and Intel® Core™ vPro® processor family-based laptops.
- Look for the Thunderbolt™ icon on your PC (next to the USB-C port) or check the product I/O specification for Thunderbolt technology.
What is the difference between Thunderbolt™ and USB-C?
- USB-C stands for the USB connection with compact Type-C ports.
- Thunderbolt™ is the top-of-the-line solution within the USB-C family.
- While the shape of all USB Type-C ports is the same, the performance, display and power capabilities, and connection experiences, differ significantly.
- Thunderbolt™ technology offers a truly universal, reliable, and high-performance one cable solution regardless of computer or accessory brand.
How is Thunderbolt™ 4 different from Thunderbolt™ 3?
Thunderbolt™ 4 technology increases minimum performance requirements, expands end-to-end solution capabilities, and is USB4 specification compliant. Specific improvements on Thunderbolt™ 4 (over Thunderbolt 3) include the following:
- Thunderbolt™ 4 technology raises the minimum required PCIe bandwidth (up to 32Gbps) to enable high-speed data transfers.
- Docks and monitors can have more Thunderbolt™ ports (up to 4) to simplify the modern workspace.
- For thin and light notebooks that require less than 100W to charge, at least one computer port is required to support charging.
- Laptops with Thunderbolt™ 4 ports connected to Thunderbolt docks wake up with a touch of the keyboard or mouse even when the lid is closed.
- Intel® Virtualization Technology for Directed I/O (Intel® VT-d) based security helps prevent peripheral devices from unauthorized access to system memory.
- Laptop Thunderbolt™ ports have more power (15W) available to run accessories.
- Universal Thunderbolt™ cables offer 40 Gbps and are up to 2 m to make cable selection fast and easy.
