Radeon HD 6620G + HD 7450M Dual Game Requirement Analysis
Radeon HD 6620G + HD 7450M Dual is a combination of a Radeon 6620G (integrated graphics) with a Radeon HD 7450M (dedicated).
This combination is called Asymmetric CrossFire and can also lead to Micro Stuttering.
The performance depends largely on the driver support for the 3D game and may even be worst than a single Radeon HD 7450M performing by itself. In any case, both cards are overall very weak and thus their combination is far from good.
