USB 3.2 Promises 20Gbps Speed Over Existing Type-C Cables

Share:

An upcoming USB standard, USB 3.2, is promising 20Gbps speeds over existing Type-C cables. The new standards hints at a likely upgrade path for Apple’s future Macs.

On Tuesday, the USB 3.0 Promoter Group said that USB 3.2 connections will offer two lanes operating up to 10 gigabits per second. Both the source and target devices must be 3.2-compatible, but the Type-C cable in between can be an existing 10-gigabit one.

The USB 3.2 standard is currently in a “final draft review phase” and is expected to officially debut in September. Apple is notably a member of the Promoter Group, making it likely to be an early adopter.

    The big takeaway here is “existing cables”. Not having to buy yet another set of cables is a relief.

    It’s going to take a while, but it’ll be really nice when we finally see USB-C ports everywhere, the way we see USB-A now. No more USB micro, mini, USB-B, etc, etc… just USB-C on both ends.
