AMD's Llano APU platform combines CPU and GPU to make for its latest in integrated graphics, and by latest we mean a DirectX 11 GPU right on the processor die itself. It doesn't stop there; Llano also introduces Hybrid Graphics technology to tie the resources of integrated and discrete graphics solutions together in Dual Graphics mode.
Neoseeker returns to the A8-3850 APU (with its integrated HD 6550D GPU) and pairs it with an ASUS Radeon HD 6670 to put Dual Graphics to the test. Hit our performance review to see if this Llano/HD 6670 hybrid is greater than the sum of the parts.

What I would like to see in the future is if they used the same architecture in their IGP as they do in the entire GPU line up so it could be paired with any card (x600 to x900 series) that way anyone looking for a chip to 'augment' their performance would consider the APU as a serious gaming alternative.
In your article there is a chart with tests on non DX11 games, as this chart reflects exactly what is happening to my crossfire setup I've thought the game I played (Battlefiled 3, multiplayer) does not support the DX11, but it does. Could it be that I don't have the DX11 installed or enabled somehow?
Also, someone told me that the APUs low bandwidth could slow the dedicated GPU down. That's why the dual graphics works poorly. Is this possible?
Have you tested with many games? As you can see in my article, some do not show performance gains. In my case, it was Street Fighter IV. I suggest you test with the Unigine Heaven benchmark to see if your scores are similar.
Even though you use slower RAM than our test setup, you should still see the benefits of dual-GPU.

Here's what I've done step by step:
With the 6670 not plugged in I've setup BIOS to use the primary display graphics ONBOARD - Installed the latest AMD Catalyst (12.8) - Plugged in the discreet card and swiched monitor cable from onbord DVI to the dedicated DVI - Enabled in Catalys the AMD Dual Graphics option (there is no Crossfire option only this one)
After I've read some opinions I found out that monitor should be in onbord port as you also mentioned and I've changed it then disabled and re-enabled dual graphics. Here's a printscreen:
Actually I have this two items and crossfiring them didn't improved graphics at all. In fact the video quality and in-game FPS was reduced as if I was using the APU integrated graphics only. Could this be a problem of drivers? Note that I've installed latest drivers from AMD (12.8 and 12.9 cat1).
You may have to enable it via the Catalyst Control Panel. Also, make sure your monitor is plugged in the motherboard video output.

I was wondering about that. I saw a laptop in Wal-Mart with an A8 and I can't remember, but I think it said A8-6550 and had the 6550 GPU. Didn't know it had a GPU on the CPU die.

Nice review Carl.
I am actually impressed the performance increase was so good when the two were combined
