I have an AMD 5700XT in my Windows games machine, and the driver is an absolute travesty. And looking over the installed files is a horror show. Qt5WebEngineCore.dll and avcodec-58.dll, because a browser engine and ffmpeg are essential in a device driver. And why does FacebookClient.exe exist? Fuck knows.
Also don't forget that these are user-space apps that are simply bundled with the driver but not necessarily part of it. Qt5WebEngineCore.dll is most likely used by the UI portion of the driver (settings dialogs, radeon software etc.), same with the ffmpeg dll and the facebook client.
NVIDIA does the exact same btw. - see [1]

For anyone using Nvidia on Windows, here's a useful tool to carve out most of the trash from the driver prior to installing.
