Thunderbolt 5 Could Reach 80 Gbps, Leaked Picture Shows

On a recent trip to Intel’s labs in Israel, Gregory M Bryant, the executive vice president & GM of Intel’s Client Computing Group, took some photos and later shared them on Twitter. According to Anandtech, one of the tweets (which was later deleted) appears to show a poster on the office wall with information about the as-yet-unannounced Thunderbolt 5 protocol.

The poster says that Intel is targeted “80G PHY Technology,” which implies that it is going for an 80 Gbps connection, which would be double the bandwidth of today’s Thunderbolt 4 and USB 4 connections. The poster also says “USB 80G is targeted to support the existing USB-C ecosystem,” which strongly implies that Thunderbolt 5, like its predecessors, will use a USB-C connector.
