Is my graphics driver dedicated in dell inspiron 5559?

Hi,

Check the device manger, under the display adapter tab, if it shows only Intel or AMD as well. As it can also be configured with a discrete card.

The AMD GPU is a co-processor for the Intel GPU - it's not a true discrete video chip.

It shows both AMD Radeon R5 M335 and Intel HD Graphics 520

AMD card is 4GB but in my PC when i show graphics dedicated memory it only shows 128 mb.

From the desktop screen, press windows key + R, which will open the run command box. Type Dxdiag in the box. It will open the DirectX diagnostics. Please select the save the information. Which will save the information in a text file. Please share the file, if possible through a private message by clicking on my name. Also where did it show that the graphics was 128MB ideally this would be for the Intel graphics.

I have sent you a dxdiag report file text and a picture where it shows only 128MB dedicated video memory.

Look under display adapters in your device manager - are there two display adapters listed, or just one?

There are both under display adapters.

Only the Intel GPU has a connection to the display -- dxdiag may not see the AMD co-GPU.  Try something like GPU-Z to see what it reports.

So if you are part of dell manufacturing community please tell me what dell has fitted in my laptop.
Both GPUs are connected to display or not.
Whether i can use AMD GPU only.
GPUz shows both.

My question is simple AMD GPU is dedicated or not.
I can use AMD GPU only.
AMD GPU is connected to display or not.
AMD GPU is same like in desktop or not.

The video system is muxless (no hardware multiplexer) -- it's entirely software controlled.  The AMD GPU is a co-processor - it isn't and cannot be made to be the primary GPU in the system.
