AMD Dual Graphics Technology
Just like Llano, Trinity supports Dual Graphics technology that allows building an asymmetrical CrossFireX configuration from the graphics core integrated into the processor and an external graphics card. Although this technology is not quite polished off in the new platform yet, and the integrated Radeon HD 7660D can now only be paired with a discrete graphics card from the HD 6000-series. It is also important to remember that for the best result the performance of the discrete graphics card should be about the same as the performance of the processor graphics core. In other words, the best choice for pairing with A10-5800K would be Radeon HD 6670 or Radeon HD 6570.
We tested this technology with a Radeon HD 6570 graphics accelerator. It can be activated very easily. When you install the add-on graphics card and enable Multi-Monitor mode in the BIOS, the driver offers you to connect additional resources.
This is how performance changes in this case:
Ideally, Dual Graphics technology should produce a positive and very noticeable effect. In our specific case, when we had two GPUs with almost the same potential, the tandem’s performance improved by about 50%. However, unfortunately, this impressive improvement revealed how greatly this technology depends on driver optimizations. For example, the performance may actually drop in new games, which driver has not yet been optimized. So, even though Dual Graphics remains a very interesting way of improving the performance of Trinity systems, we wouldn’t encourage resorting to it just yet, unless you are an experienced user and are ready to check the Dual Graphics efficiency every time you launch a new game.
