The next-generation Thunderbolt is based on the specification of ' USB4 Version 2.0 ', the details of which were released on October 19, 2022, and supports high-speed data transfer and transmission of video signals with low delay and high resolution. About.

It has 80 Gbps, which is twice as much as Thunderbolt 4, which had a bandwidth of 40 Gbps in both directions, and the PCI Express data throughput is doubled.

The next-generation Thunderbolt also supports

DisplayPort 2.1 , whose specifications were released on October 18, 2022. When the next-generation Thunderbolt recognizes a high-resolution display that requires a lot of bandwidth, it automatically adjusts the bandwidth and provides a bandwidth of 120 Gbps for transmission and 40 Gbps for reception. This is a feature brought by USB4 Version 2.0 and these dynamic adjustments support dual displays up to 8K at 60Hz.

Next-generation Thunderbolt is compatible with previous versions of Thunderbolt, USB, and DisplayPort, and 'new signal technology' allows existing Thunderbolt 4 cables up to 1 meter in length to be used as is.

'Intel has always been a pioneer and leader in the wired connectivity industry,' said Jason Ziller, head of Intel's Client Connectivity Division. I am very happy to be able to lead.'
