Radeon HD 7640G + HD 7670M Dual Game Requirement Analysis
Radeon HD 7640G + HD 7670M Dual is a combination of a Radeon 7640G (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 relies a lot on driver support and is, at times, worse than a single Radeon HD 7670M performing by itself.
