The transfer speed of Thunderbolt 5 is '80 Gbps', which may be double the current rate



From an image posted on Twitter by Intel's senior vice president of client computing, Gregory Bryant,

Thunderbolt 's next-generation standard, Thunderbolt 5, can double the bandwidth of the current one and achieve a transfer rate of 80 Gbps. It turned out to be sexual.

Intel Executive Posts Thunderbolt 5 Photo then Deletes It: 80 Gbps and PAM-3

On August 2, 2021, Mr. Brian posted four images on Twitter when he visited a research and development facility in Israel. However, Bryant immediately deleted the post and reposted three images.




The one image that disappeared is below. The poster on the wall of the facility says '80G PHY Technology', which is believed to be the Thunderbolt 5 technical specification.



According to AnandTech, a tech media that reported this, 80G PHY Technology is the

physical layer (PHY) for 80Gbps connection, and Intel realizes twice the bandwidth of the current latest standard 'Thunderbolt 4'. It means that we are working on it for the sake of it. In addition, the text on the second line that follows shows that the new standard will be realized while preserving the existing USB Type-C connector. This bandwidth is expected to be achieved in Thunderbolt 5, including support for higher refresh rates on monitors with 4K and 8K resolutions.



The poster also states that 'PHY is based on the new PAM -3 modulation scheme,' and AnandTech states that 'PAM3 is somewhere between quadruple pulse amplitude modulation (PAM4) and non-zero regression (NRZ).' , Achieve higher bandwidth. ' At the end of the poster, 'N6 test chips focused on new PHY technology show promising results in research facilities,' AnandTech said, 'N6 is TSMC 's technology, but it's the same. I don't know if there is one. '
