** 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.
- CrossFire™
-
- Multi-GPU technology
- Four modes of operation:
- Alternate Frame Rendering
(maximum performance)
- Supertiling (optimal load-balancing)
- Scissor (compatibility)
- Super AA 8x/10x/12x/14x
(maximum image quality)
- Native CrossFire support simplifies setup by requiring no dedicated slave or master hardware
- 24-bit CrossFire connection enables high resolutions and refresh rates
- Supports the broadest range of platforms for both Intel and AMD
