[opensuse-support] amd graphics card on laptop and slowness
So I have been using this Dell Inspiron 15 5576 (laptop #1 below) and have not been generally happy with its performance. Sluggish, sometimes freezes, can't suspend to ram, and a few other minor irritations. Should run really fast with the amount of memory it has.

I found a thread indicating maybe a problem with the graphics card? So I looked up my specs on Dell, and this is supposedly the graphics card I have:

AMD FX 9830P Quad-Core Processor with Radeon R7 Graphics

However, here is what the hardware info detects:

So it detects 2 controllers, is calling one of them an "ATI Carrizo" and the other one an "ATI Baffin [Radeon RX 460]". The Dell specs say it is Radeon R7 but opensuse is saying Radeon RX 460. Is this right?

And also, is the amdgpu driver sufficient? I found this thread in the forums https://forums.opensuse.org/showthread.php/528306-amdgpu-pro-driver-issue

that seems to indicate I need to download the new amdgpu-pro driver. So I downloaded the driver from here https://support.amd.com/en-us/kb-articles/Pages/AMDGPU-PRO-Driver-for-Linux-Release-Notes.aspx#

but I haven't installed it yet. Am I on the right path here?
