Intel is about to launch Thunderbolt 5, which will double the function of the USB-C interface

Intel executive Gregory Bryant posted on Twitter photos of the surrounding Intel team’s laboratory in Israel, and one of them contains some details about the upcoming Thunderbolt 5 standard, indicating that Intel’s Israeli team is working on the Thunderbolt standard. , And it is also the Thunderbolt 5 interface standard.

The photo reveals two key details of Thunderbolt 5. First, the upcoming standard will support twice the bandwidth of Thunderbolt 4-up to 80gbps. While doing so, it still uses USB-C as a port, which means that Thunderbolt 5 will continue to be compatible with existing machines.

More interesting news is how Intel achieved dual bandwidth. It uses Pulse Amplitude Modulation (PAM), which uses a combination of two binary digits to transmit two bits of data in each cycle, unlike traditional transmission methods that only carry one bit of data.

PAM-3 is specifically mentioned in the photo. Without further research, PAM-3 provides 3 bits of data in two cycles. A string of three numbers -1 or 0-determines whether the module will transmit -1, 0 or +1 in two cycles. This allows Intel to increase the bandwidth of Thunderbolt 5 by transferring more data in each cycle.

Although the information is credible, it does not mean that it is specific. After this photo began to circulate, it was quickly deleted, and this suspicious photo was deleted again on Twitter. This photo does not actually mention Thunderbolt 5, but it mentions “80G PHY technology”, which is most likely Thunderbolt 5.

However, it may take a while before we hear any news about Thunderbolt 5. Thunderbolt 3 was released in 2015, and it took five full years for Thunderbolt 4 to start shipping. Thunderbolt 4 is still not widely adopted, as evidenced by the fact that a large number of Thunderbolt 3 docking stations are still available.

Nevertheless, Thunderbolt 5 is gradually becoming a leap forward of Thunderbolt 4. With double the bandwidth, Thunderbolt 5 connections may be able to connect more ports, higher resolution and refresh rate displays, as well as more display Thunderbolt connections through a single display.

However, it is too early to say about the capabilities of Thunderbolt 5.
