Intel announces Thunderbolt 5 with up to 120Gbps bandwidth

Thunderbolt 5 will bring significant improvements including support for up to three 4K 144Hz displays and 240W charging.


  • Thunderbolt 5 provides a significant increase in bandwidth up to 120Gbps, three times that of Thunderbolt 4, helping to support more displays and faster charging.
  • The new connection of Bingu 5 uses four channels carrying 40Gbps each, providing 80Gbps of bi-directional bandwidth in a fixed system, but it can update the roads up to 120Gbps of data transmission.
  • Thunderbolt 5 also introduces support for charging laptops up to 240W, making it suitable for electronic devices such as gaming devices and production laptops, while Thunderbolt 4 will still be used by ordinary users.

Intel has been teasing Thunderbolt 5 for almost a year now, but today, the company unveiled the technology. Thunder 5 will provide a bandwidth of 120Gbps, three times more than Thunder 4, with support for more and faster displays and additional power, all using a single cable.

Thunderbolt 5 has more bandwidth

The main draw with the Thunder 5 is the amount of data that can be carried using a single USB Type-C cable, and it is the Thunder 5, which goes to 120Gbps, three times the 40Gbps offered by the Thunder 4. There is a little warning about this. , however, since this bandwidth is only possible using a dedicated transmission method.

In fact, the connection of Thunder 5 has four lanes carrying 40Gbps each, and normally, it will use two channels in each direction, providing 80Gbps of bi-directional bandwidth, double what Thunderbolt 4 offers. But if it sees how much bandwidth is needed, such as high-quality displays, Thunderbolt 5 can rearrange the lanes so that three of them go to the entrance, allowing your computer to send 120Gbps of data and receive up to 40Gbps. .

This higher bandwidth allows support for all new formats, up to three 4K displays running at 144Hz are supported, and support for dual 6K displays is now limited. There’s good news for gamers, too, with Intel promising to support displays up to a super-refreshing 540Hz.

Of course, the increased bandwidth will also benefit external storage and GPUs that support Thunderbolt connectivity. The USB data protocol now supports up to 20Gbps bandwidth, although the minimum requirement is at 10Gbps. Thunderbolt 5 supports DisplayPort 2.1, USB4 v2.0 (80Gbps), and PCIe 4.0.

240W charging is coming

Another improvement that comes with Thunderbolt 5 is the ability to charge your computer up to 240W, making this a useful solution for laptops with high power, such as those for developers or gaming devices. It’s worth noting that 240W support is optional, though. The minimum power supply requirement for laptops is 140W.

With the Thunder 4, 140W was the maximum speed, when only 100W was needed. As for the minimum power required for the extension, it is at 15W.

Thunderbolt 4 is not going away

Interestingly, Intel is not using the Thunder 5 as a direct reference to the Thunder 4. Instead, the Thunder 5 is designed for enthusiasts who will benefit most from the increased bandwidth and capabilities of the new processor. The company expects the adoption to be very fast among developers, gamers, and users. Office users and the general public will continue to use Thunderbolt 4 in the future.

Thunderbolt 5 also seems unlikely to be built into Intel’s next-generation processors. Intel is introducing the technology via a discrete chip, codenamed Barlow Ridge. You can expect to see Thunderbolt 5 starting to appear on devices in 2024.
