This is normal and not much of a story.
You could always install the latest AMD GPU driver, the risk is the same anytime you update a GPU driver, you could have issues though(That still does not go away as these are not actively being validated).
It is the same with a laptops and discrete GPU, go take a look at the graphic drivers included from the manufactureres website, Usually it is the original driver when the laptop released... You can always update to latest(Some for like HP you need to install directly but there is always a way to add them). The OEM/manufacturers seldom will revalidate old platforms unless there isa big performance or security bug included in the initial drivers. That's why this is expected behavior, you'll get a functioning driver from the OEM, but if you want the best performance you'll ahve to take the risk of using a direct AMD/NVIDIA driver that was just released but hasn't been and likely never will be fully validated for your unique product.
