The integrated graphics cards in a laptop are normally part of the main board and are not upgradable.
Laptop in question uses a mobile AMD A10-5750M Richland APU with Radeon graphics core embedded in the processor die. You can replace the graphics chip by replacing the CPU, same as with desktop APUs.
@ceasefire If the board's BIOS allows it (check the board's CPU compatibility list) you can upgrade the graphics by getting a socket FS1r2 Richland mobile APU with a desired graphics core. I think that exact same APU model has a series with an 8650G core.
I'm not sure how much that would cost though, I personally never bought a mobile processor or even saw one for sale, plus it pretty much feels like a pointless exercise for a laptop.
