"AMD wrote drivers for its own Radeon GPUs in order to support an external graphics chassis. Radeon cards running Radeon Software 16.2.2 or later are capable of plug-and-play configuration with an external chassis. The new software can monitor which applications are running on an external GPU and offers the option to close current applications and prep the system for safe removal. Unlike previous solutions, you can connect or disconnect an external dock without rebooting the system."
"Razer built the first system to support this feature (the Razer Blade Stealth) and is the first company to adopt the BIOS extensions and capabilities required to allow for PCI Express hot-plugging. Razer also built the first desktop chassis (the Razer Core). Right now, the Razer Blade Stealth and Razer Core are the only compatible products on the market, but that will change with future launches."
