Here are the Professional GPU Drivers for the FireGL V series GPU Cards: AMD Drivers and Support for Radeon, Radeon Pro, FirePro, APU, CPU, Ryzen, desktops, laptops
Download a small program called GPU-Z and that will tell you the FireGL Vxxx version you have installed. GPU-Z Graphics Card GPU Information Utility
EDIT: Checked the earliest V3100 to V8650 all have Drivers for Windows 7 and below only. In case you have Windows 10 installed there are no drivers for that Windows version.
