With enhanced performance, Thunderbolt 5 offers significant improvements in bandwidth and speed in compatible devices. These advancements in digital connectivity set new standards for data transfer speed, efficiency, and compatibility.
Here’s how it connects with your gear—and what to expect:
Thunderbolt 4 Devices
Got a Thunderbolt 4 hub, cable, or SSD? Plug it into a Thunderbolt 5 port, and it’ll work just fine. You’ll get Thunderbolt 4’s full 40 Gbps speed and power delivery, with no problems. Your existing setup—say, a 4K monitor or external drive—runs as smoothly as ever, and Thunderbolt 5’s extra bandwidth could even give a slight performance nudge when juggling multiple devices. Similar to Thunderbolt 5, Thunderbolt 4 is backward compatible with all previous versions of Thunderbolt.
Thunderbolt 3 Devices
Thunderbolt 5 also connects seamlessly with Thunderbolt 3 gear. That external GPU, SSD, or dock you bought a few years back? It’ll connect without a hitch, capable of running at Thunderbolt 3’s max speed of 40 Gbps along with supported power delivery. You won’t hit 80 Gbps with these older devices, but Thunderbolt 5’s improved data handling could still speed up file transfers or reduce lag compared to a Thunderbolt 3-only system.
Thunderbolt 5 also enhances high-speed data transfer, making it ideal for demanding applications like video editing and managing large datasets.
No adapters are needed—just plug in and go.
USB-C Ports and Devices
Since Thunderbolt 5 uses USB-C connectors, it works with any USB-C device. Have a laptop with standard USB-C (not Thunderbolt)? You can still connect Thunderbolt 5 accessories, though you’ll be limited to the port’s speed—usually 10 Gbps for USB 3.2 Gen 2 or 20 Gbps for USB 3.2 Gen 2x2. Some USB-C ports do not support video output, so check the specs of your port to know what to expect.
Thunderbolt 5 also enhances the performance of storage devices connected via USB-C, offering quicker data transfer speeds and improved read and write capabilities. USB-C drives, phones, or monitors will function, too, tapping into Thunderbolt 5’s display and power perks if supported. It’s a universal fit that keeps your options open.
Compatibility with USB4
Thunderbolt 5 takes compatibility to the next level by seamlessly integrating with USB4 version 2.0 and DisplayPort 2.1 standards supporting up to 80Gbps with USB. This integration ensures that users can enjoy the benefits of Thunderbolt 5's high-speed data transfer and enhanced display performance while maintaining backward compatibility with existing USB4 and DisplayPort devices. Whether you're connecting multiple high-resolution displays or transferring large files, Thunderbolt 5's versatile connectivity options provide a future-ready solution that maximizes both speed and efficiency.
What About Performance Limits?
Here’s the catch: while Thunderbolt 5 supports your older gear, their performance still caps at their original specs and won't be able to utilize all of Thunderbolt 5's enhanced capabilities. Support for PCI Express Gen 4 enables faster data transfer rates, improving storage and graphics capabilities. A Thunderbolt 3 SSD won’t suddenly hit 80 Gbps—it’s still 40 Gbps max. But Thunderbolt 5’s smarter bandwidth management means you’ll notice less slowdown when mixing old and new tech—like running a Thunderbolt 3 drive and an 8K display at once. It’s about keeping everything humming along, not leaving anything behind.
Cable Tip
For Thunderbolt 4 or 3 devices, your existing passive cables work—but over 2 meters, you’ll need active cables (with built-in signal boosters) to maintain top speeds. More on cables later.
In short, Thunderbolt 5 welcomes your current setup with open arms. You get to keep using what you’ve got while unlocking new possibilities as you upgrade.
Cables You’ll Need for Thunderbolt 5
Thunderbolt 5’s full potential depends on the right cables.

Here’s the rundown on what to use and why it matters:
-
Thunderbolt 5 Cables: To hit 80 Gbps (or 120 Gbps with Bandwidth Boost), you need cables certified for Thunderbolt 5. They’re built to handle the extra speed and power (up to 240W). These cables enable devices to reach their maximum speed potential, improving performance in data-intensive tasks. Look for the Thunderbolt logo and “5” on the packaging—don’t settle for less if you want the max.
-
Thunderbolt 4 Cables: Existing Thunderbolt 4 cables will still work with Thunderbolt 5 devices but only support up to 40Gbps. Fine for older devices, but they won’t unlock Thunderbolt 5’s full speed.
-
Passive vs Active: For short connections (under 2m), passive cables are less expensive and reliable. Going longer? Active cables, with tiny circuits inside, keep the signal strong—essential for 80 Gbps over distance or big multi-monitor setups.
-
USB4 Cables: USB4 cables work with Thunderbolt 5 devices since both use USB-C connectors, but their performance varies. Certified USB4 cables can hit 40 Gbps—or 80 Gbps with USB4 Version 2.0—but check the specs, as some only support 20 Gbps. They’re a solid choice for mixed setups with USB4 or Thunderbolt gear.
- USB-C Cables: Generic USB-C cables might connect, but most top out at 10 Gbps or less. Skip them unless you’re just charging or using basic USB devices.
What to Do: Check your setup. If you’re sticking with Thunderbolt 3 or 4 gear, your current cables are likely fine. Upgrading to Thunderbolt 5 speeds? Grab a certified Thunderbolt 5 cable (active if over 2m) from Cable Matters or another trusted brand. It’s a small investment to unleash the full 80 Gbps and 240W goodness.
