The driver is a software package that allows Windows to communicate with an AMD Radeon R7 series GPU (Graphics Processing Unit), enabling the full functionality of your graphics card. The driver enables your computer to use the GPU for rendering graphics, running 3D applications, playing games, video playback, and other tasks that require hardware acceleration.

The Radeon R7 series includes a range of graphics processors, which might be integrated into AMD's APUs (Accelerated Processing Units) or as standalone discrete graphics cards. The driver ensures that your system is able to take full advantage of the GPU's capabilities, whether it's an integrated or discrete solution.
