You usually let windows install the default drivers (yes its real) just get them working.
But unless the hardware predates win10 (in which case the drivers would be the latest), you still should go get the latest drivers from AMD.
Default drivers are usually not up to date and while they would run fine, usually you'll get way better performance with the ones from AMD website.
Applies to all hardware.
Its better than before where windows would just install "generic VGA driver" that doesnt do anything other than show the stuff on the screen.
