Windows 11 now has the capability to achieve data transfers of up to 80 Gbps through USB4, as introduced in the recent OS update (build 23615), aiming to support advanced monitors, storage devices, and connectivity technologies, according to Microsoft.
Windows 11 can now achieve USB4 transfers of up to 80 Gbps.

USB4 specifications were unveiled in August 2019 and made their way to Windows 11 after two years. However, achieving an 80 Gbps transfer rate was not yet feasible. It was only in September 2022 that the second generation of USB4 specifications was released, introducing 80 and 120 Gbps transfer modes.
The USB4 transfer limit on Windows PCs has increased from 40 Gbps to 80 Gbps, with support now available for notebooks featuring 14th-generation Intel Core processors from the HX series, like the new Razer Blade 18.
The USB 4 2.0 standard is compatible with devices designed for earlier USB and Thunderbolt generations that utilize the USB type C connector, eliminating the need for users to purchase newer computers for compatibility with older peripherals.
Introduction and release date
Support for 80 Gbps transfers through USB 4 2.0 was added in the Windows 11 update for Windows Insider program participants who received the update via the Dev channel. The timing for this feature to reach the stable channel for general consumers is currently unknown.
