Thunderbolt 4 2.0: Intel releases first Demo

They are participating in Intel's 2022 Technology Tour at the Intel Design Center in Haifa, Israel. Today, Intel showed the first test demo using the Thunderbolt protocol at 80 Gbps. The 80 Gbps Thunderbolt transmission may use a similar specification to USB 4 version 2.0 announced earlier this month. Intel hasn't shared many details at this time, and the demo featured dual Thunderbolt channels running at 40 Gbps each (80 Gbps total), which is twice the performance of Thunderbolt 4.

At present, Intel has not announced the name and launch time of the new Thunderbolt protocol. Foreign media speculate that the 80Gbps Thunderbolt protocol may be called Thunderbolt 4 2.0.

Earlier this month, the USB Promoter Group announced the  USB4 Version 2.0 standard, which can achieve data transmission of up to 80 Gbps (10GB/s) through a USB Type-C cable. According to reports, USB4 Version 2.0 is based on a new physical layer architecture and is backward compatible with USB4 Version 1.0, USB 3.2, USB 2.0, and Thunderbolt 3 standards.
