The AMD Mobility Radeon HD 6970M Crossfire (or sometimes called ATI Mobility Radeon HD 6970 X2) is a combination of two high-end graphics card for big and heavy laptops. Usually, each single card renders a single frame (AFR mode). Therefore, it may suffer from micro stuttering in low fps ranges of 30fps. This happens because of different timespans between two frames (e.g., irregular delays between sequential frames).

The HD 6970M is most likely based on the desktop HD 6850 graphics card. The codename of the mobile core is Blackcomb XT and it should have a similar power consumption as the GeForce GTX 480M. According to the roadmap ,the Blackcomb-based chips should feature the UVD3 video processor and Eyefinity+ support.
