AMD Radeon HD 6755G2
The AMD Radeon HD 6755G2 is the combination of an integrated AMD Radeon HD 6620G or 6520G APU processor graphics card and a dedicated entry level AMD Radeon HD 6750M graphics card in CrossFire combination. This setup, called AMD Dual Graphics or asymmetric CrossFire, uses AFR (Alternate Frame Rendering) to render alternating frames between the two graphics cores. As a result, the combination also suffers from the phenomenon known as micro stuttering.
The performance of the Radeon HD 6755G2 depends greatly on the driver support in games. In some games, the performance may even degrade by 10-15% compared to using only the APU graphics card. As of June 2011, only DirectX 10 and 11 graphics modes are supported and therefore lower settings and older games are not accelerated. Due to the micro stuttering and performance issues, AMD Dual Graphics may impose more problems than performance gains.
Supported Features like PureVideo HD (UVD3) and OpenCL have similar performance to a discrete Radeon HD 6750M.
As both graphics cards are rendering frames, the power consumption is clearly greater than if only one GPU was active.
