HDCP - High-bandwidth Digital Content Protection
- HDCP is a content protection specification to protect digital entertainment content across the DVI/HDMI interface. The HDCP provides a robust, cost-effective and transparent method for transmitting and receiving digital entertainment similar to DVI/HDMI-compliant digital displays. HDCP encrypts the data transmitted between the DVI/HDMI connector on the graphics adapter and the display. To provide this support, both the graphics adapter and the display need to have an HDCP transmitter and receiver respectively.

CrossFire Multi-GPU Technology
- Scale up rendering performance and image quality with 2 or more GPUs
- Integrated compositing engine
- High performance dual channel interconnect.
