The next USB standard will double existing speeds even with an older cable

There’s a new, super-fast version of USB 4 on the horizon, and you don’t even have to buy a brand new cable to take advantage of it. The USB Promoter Group advises that the next-generation USB 2.0 standard is “pending” and will double the bandwidth of existing USB 4 ports from 40Gbps to as high as 80Gbps.

Surprisingly, the new standard is also backwards compatible with previous USB 4 cables. This means that when the new standard becomes available, existing 40Gbps USB-C cables will also get the higher speeds. From the press release: “Key features of the updated USB4 solution include: Operation at up to 80 Gbps, based on a new physical layer architecture existing passive 40 Gbps USB Type-C cables and redefined active 80 Gbps USB Type-C cables.”

How this is possible was not explained by the USB Promoter Group, but by a spokesman for the organization The edge It was “a requirement when the new specification was being developed and the details of how 80 Gbps signaling will be achieved will be announced once the final specification is released.”

It is not yet clear when the new standard will actually reach consumers. In their press release, the USB Promoter Group said that “the update is currently specifically aimed at developers,” so it could be some time before the rest of us can get computers with the new super-fast connector.
