USB-IF earlier announced the launch of the USB 3.2 design specification based on the USB Type-C connection format. This will enable existing USB Type-C cables that support SuperSpeed 10Gbps certification to support higher transmission bandwidth through dual-channel transmission, suitable for use with external graphics card boxes or external storage devices.
The USB 3.2 design specification, if both ends of the connector are designed with the same connection specification, will be compatible with existing SuperSpeed data transfer rates and encoding modes, and the overall data transfer capacity will be increased through dual-channel mode. This corresponds to dual-channel 5Gbps or dual-channel 10Gbps transmission modes, allowing the overall transfer rate to be more than doubled, allowing USB Type-C devices to natively support external graphics cards and higher-speed storage devices.
The USB 3.0 design specification is currently in the final review phase, with the official release expected to take place in the US during the USB Developer Day event in September.
Intel has already developed Thunderbolt 3 based on the USB Type-C port specification and plans to integrate the necessary authentication chips into its processors starting next year, thereby lowering the actual price of Thunderbolt 3 peripherals and promoting widespread use of Thunderbolt 3 ports. However, USB Type-C may have a better chance of widespread adoption.
