In all likelihood, your laptop only has integrated graphics (iGPU). The A8-6410 APU has an iGPU that is simply referred to as the Radeon R5 with no model number. Click below for more info about the A8-6410. It states on average the Radeon R5 is about equal to the Intel HD 4200 iGPU.

That is a pretty weak iGPU especially since the Intel HD 4200 is actually a little less powerful than the Intel HD 4000 iGPU. For a laptop that costs about $370 I would not expect it to have a dedicated GPU.
