AMD has introduced XConnect, a form of driver-level support for external graphics cards, as part of its latest Radeon 16.3 driver. XConnect allows users to add and remove a Thunderbolt 3 external graphics device (eGFX) such as the Razer Core, without needing to restart the PC, as well as switch between discrete and integrated graphics on-the-fly.
The XConnect driver can also detect what applications are running on the external GPU, giving users the option to close them individually, or shut them all down at once from a pop-up menu in the system tray. Even if users forget to close down applications before removing the external GPU, AMD claims that the system will remain functional after a "surprise removal."
The first device to use XConnect will be the Razer Blade Stealth and Razer Core. AMD promises that its XConnect driver will be compatible with other systems and external GPU devices, provided they meet a few criteria. Devices must be running Windows 10 build 10586 or later and Thunderbolt firmware v.16 or higher; feature a Thunderbolt 3 port and 40Gbps Thunderbolt 3 cable; and pass Thunderbolt certification. Most importantly, the systems must have BIOS ACPI extensions for Thunderbolt eGFX.
