Radeon HD 8650G + HD 8570M Dual Game Requirement Analysis
Radeon HD 8650G + HD 8570M Dual is a combination of a Radeon 8650G (integrated graphics) with a Radeon HD 8570M (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 8570M performing by itself. This is due to poor driver support.
However, on some games the performance did exceed a dedicated GeForce GT 640M.
