* AMD’s ATI Radeon™ X and Radeon™ 9550 series of GPUs are capable of processing HDCP signals ("HDCP ready"), however not all ATI Radeon graphics cards are HDCP ready. Please check the applicable ATI Radeon graphics card specification to determine if a particular ATI Radeon graphics card is HDCP ready. Some third parties manufacture graphics cards containing ATI Radeon GPUs -- you can inquire of them which models, if any, are HDCP ready. In addition, playing HDCP content requires additional HDCP ready components, including but not limited to an HDCP ready monitor, disc drive, multimedia application and computer operating system.
**with optional HDTV adapter available from ATI Online Store
CrossFire™
Multi-GPU technology
Inter-GPU communication over PCI Express (no interlink hardware required)
Four modes of operation:
Alternate Frame Rendering (maximum performance)
Supertiling (optimal load-balancing)
Scissor (compatibility)
Super AA 8x/10x/12x/14x (maximum image quality)
HyperMemory™ 2***

*** ATI HyperMemory2 is an optional feature that may not be implemented in some board configurations. ATI HyperMemory is the cumulative total of local and system memory used by the Graphics Processing Unit (GPU) intended for use in the processing and creation of 3D and other images. The amount of HyperMemory is determined by the amount of local memory and available system memory.
