AMD 8650G
AMD 8790M
Both of these are Terascale 3 Based GPU., which are supported exclusively by the Legacy AMD Catalyst Drivers
(Catalyst 15.7.1 and 16.2.1 Beta)
At least "Officially" this is the case. Personally speaking though, I've not had much luck with said "Legacy" / "Non-GCN" Drivers with Pre-GCN Hardware on Windows 10... in-fact all Drivers 15.7 on-ward would result in the OS Hanging after the AMD Services are loaded at Start-up.
This might not happen to you, but it's just something to be aware of is a possibility.
What I would actually recommend would be the Catalyst 15.6 (Windows 8.1 / 64bit) as these work on Windows 10,. and fully support all Non-GCN Graphics (APU / GPU).
It should be available (http://files01.tchspt.com/tempd/amd-catalyst-15.6-beta-software-suite-win8.1-64bit-june22.exe)
(AMD Catalyst Graphics Driver Beta 15.11.1 Driver - TechSpot) For a full list of Legacy Drivers.
AMD used to list all of these within an easily accessible "Legacy Release" … which now is somewhat easily missed on the Driver Site and only lists the Milestone (Recommended) Releases., not the complete list of Released Drivers.
Why they made this change when the overhauled the Website remains baffling to me.
I'd personally highly recommend either upgrading your system, or downgrading to Windows 8.1.
