Radeon HD 7660G + HD 7670M Dual Game Requirement Analysis
Radeon HD 7660G + HD 7670M Dual is a combination of a Radeon 7660G (integrated graphics) with a Radeon HD 7670M (dedicated).
This combination is called Asymmetric CrossFire and can also lead to Micro Stuttering.
Unfortunately, benchmarks indicate the performance is,at times, worse than a single Radeon HD 7670M performing by itself. This might be due to poor driver support.
