Intel Launches Thunderbolt 5 With Up to 120Gbps of Bandwidth

In a world where data transfer speeds and power delivery have become pivotal in our daily tech-driven lives, Thunderbolt 5 emerges as a groundbreaking advancement. It boosts the bandwidth from 40Gbps to an impressive 120Gbps, doubling the number of PCIe lanes, and can deliver a remarkable 240W of power via a single USB-C cable.

Unraveling the Bandwidth

In its standard setup, Thunderbolt 5 provides 80Gbps, utilizing two of its four PCIe lanes for bidirectional bandwidth. However, when greater bandwidth is required, such as for high-resolution displays, Thunderbolt 5 can allocate up to 40Gbps across three of its four lanes, resulting in a transmission of 120Gbps and reception of 40Gbps.

Spectacular Display Capabilities

This incredibly high bandwidth facilitates support for innovative display configurations, including the ability to run up to three 4K displays at 144Hz, with dual 6K displays now being the minimum standard. Gamers will also be delighted as Intel pledges to support displays with refresh rates of up to an astonishing 540Hz.

Empowering External Devices

The increased bandwidth will undoubtedly benefit external storage and GPUs that leverage Thunderbolt connections. The new tech is also compatible with DisplayPort 2.1, USB4 v2.0 (80Gbps), and PCIe 4.0.

A New Era of Charging

Another noteworthy addition to Thunderbolt 5 is its ability to charge your computer at a maximum of 240W, catering to power-hungry laptops, especially those used by creators and gamers. It's worth mentioning that the 240W charging support is optional, with the minimum power delivery requirement for laptops set at 140W.

Thunderbolt 5's Integration

Thunderbolt 5 will not be integrated into Intel's next-generation processors. The company plans to launch the technology as a discrete chip, codenamed Barlow Ridge.

Target Audience

Interestingly, Intel is not positioning Thunderbolt 5 as a direct replacement for Thunderbolt 4. Instead, Thunderbolt 5 is designed for enthusiasts who can fully utilize the enhanced bandwidth and capabilities of this new connector. The company anticipates faster adoption among content creators, gamers, and workstation users, while users in office productivity scenarios and general use will continue to rely on Thunderbolt 4.

Lastly, Intel has announced that the first Thunderbolt 5-enabled devices will be released in 2024.
