I recently switch to Linux Mint 19 from Windows 10.
I own a laptop ASUS X550DP which has A10-5750 with integrated graphic Radeon HD 8650G and discrete graphic cards AMD Radeon HD 8670M 2GB.
When I am using windows 10, I have AMD software Catalyst center to switch between Radeon HD 8650G and Radeon HD 8670M. I can't find such option in Linux OS.
Can someone here teach me how to switch graphic card usage in Linux OS?
Any little help are very appreciated.
Kind regards and thanks.

I have try using DRI_PRIME, but the result seems similar or even a little worse.
xrandr --listproviders

DRI_PRIME=1 glxinfo | grep "OpenGL renderer"
OpenGL renderer string: AMD HAINAN (DRM 2.50.0, 4.15.0-46-generic, LLVM 8.0.0)
I use my DRI_PRIME=1 which should be discrete card, and normal run to test the benchmark,
here is the result using normal run

and here is using
DRI_PRIME=1 steam steam://run/203160
to run tomb raiderhttps://imgur.com/sae3Q9j
Note : I do let my laptop to cooldown between the tests.
Am I doing something wrong in terminal?

I have try to run Tomb Raider benchmark too in Windows using high performance setting, and the result is even worse than in Linux Mint 19.
Even though I am not sure if DRI_PRIME really did change my graphic card usage, seems like this is what my laptop can do.
Second question, can I automatically active DRI_PRIME=1 in all application without doing any setting or running terminal after a reboot? If yes, please guide me.
Thanks everyone here for the help.

Verify you have amdgpu installed (which will be if you have mesa installed. Here are instructions for installing the latest mesa on Linux Mint) and test booting with the below kernel parameters.
radeon.si_support=0 amdgpu.si_support=1
Should it work better, you can make this permanent by appending this to your kernel parameters in /etc/default/grub and updating grub.
