Switchable graphics AMD Radeon HD 6620G/AMD RADEON HD 7670M

Question

I have notebook HP Pavilion dv6-6c05er with integrated in CPU graphics AMD Radeon HD 6620G. It also have AMD RADEON HD 7670M but i cannot switch between them. This is only possible with drivers that was made in 2011. Now 2014. And this is not an isolated case. There is solution for the similar problem with AMD/Intel graphics, but nothing for AMD/AMD...
This situation persists for the second year. How long will it last?

Hello, @Maxim4ik163 
I see that you have an issue with the switchable graphics running on your notebook. I will try to clarify this.
All information can be located in this document: Switchable Graphics on Notebooks Configured with Dual AMD GPUs
I will start with this " i cannot switch between them", if you're referring to switching manually you cannot do this. The graphics aren't meant for you to just switch them at will. The act of the switching is done automatically and only when the application and situation requires.
What does that mean?
With your notebook, this means that the graphics being used will only switch from intergrated to dedicated if required. With this notebook, that won't actually happen often. This explains why:
This feature is working as intended. The intended behavior of the dual AMD GPU configuration will vary depending on the application:
DirectX 9 applications (such as Street Fighter IV) only use one graphics processor at a time, even though two graphics processors are available. When a discrete graphics processor is paired with an A4-series integrated graphics processor, then data is rendered by the discrete graphics processor. When a discrete graphics processor is paired with an A6/A8-series integrated graphics processor, then data is rendered by the integrated one because it performs better than the discrete in this scenario.
DirectX 10 and DirectX 11 applications use both graphics processors simultaneously to render data.
OpenGL applications use the integrated graphics processors only.
To add to that, your notebook runs on an A8 series CPU. This means that the only time you will ever use discrete is with DX10 and DX11. When that is happening the applications will only reflect the intergrated graphics.
Anything else is explained in the document.
Now as for the driver, unfortunately to my knowledge the only one that works for this setup is what's provided on the HP site. This as you say is out of date. When or if there will be an update (so that applications requesting you to update can run), I don't have that information.
If you still have questions about how this works or the drivers, I recommend contacting phone support.
