Three months ago, USB 4 was announced, boasting speeds double that of USB 3.2. It looks like these new speeds will be available to consumers by the end of next year.
According to AnandTech, the USB-IF is optimistic that the specification will be finalised by September. That said, the USB 4 specifications was previously expected to be published by the middle of 2019. The spec is currently in version 0.7. On the flip side, the USB-IF believes that devices with USB 4 will be available by the end of 2020.
To quickly recap, USB 4 will be based on Intel’s Thunderbolt 3 interface, but with double the bandwidth. This allows it to perform two lane operations using existing USB-C cables, and up to 40Gbps using cables certified for such speeds.
While the publishing of the USB 4 specs looks to be a little behind schedule, it looks like we will see USB 4-supported devices a little earlier than expected.
