Windows 11 is now compatible with data transfers of up to 80 Gbps through USB4, introduced in the latest OS update (build 23615) to support advanced monitors, storage devices, and connectivity technologies.
Windows 11 enables transfers of up to 80 Gbps through USB4 now.

USB4 specifications were revealed in August 2019, and it took two years for them to be integrated into Windows 11. However, the capability to transfer at 80 Gbps was not attainable initially. It was only in September 2022 that the second generation USB4 specifications were introduced, enabling 80 and 120 Gbps transfer modes.
The transfer speed limit via the USB4 standard on Windows PCs has increased from 40 Gbps to 80 Gbps for notebooks equipped with 14th-generation Intel Core processors from the HX series.
The USB 4 2.0 standard is compatible with older USB and Thunderbolt devices that utilize the USB type C connector, eliminating the need for users to purchase newer computers for compatibility with older peripherals.
Introduction and release dates
Support for 80 Gbps transfers through USB 4 2.0 was added exclusively to the Windows 11 update for Windows Insider program participants who received the update via the Dev channel. The timing for its release on the stable channel, intended for the general consumer, remains unknown.
