ATI will finalize the specs of the RV560/570 in the coming weeks. The RV570 will replace the X1900 GT, it will feature roughly the same performance at a lower price.
With regard to the previous ATi’s roadmap from Gecube, sources indicate that RV560/570 are neither 12 Pixel Shader Processor nor products based on RV530 (Radeon X1600 family) plus CrossFire Compositing Engine. In addition, to complete with nVidia 80nm G73-B1, which supports HDMI Signal Mixing and is expected in production in Q4, ATi is going to release RV550 to give HDMI Signal Mixing support to HTCP.
On the other hand, it’s confusing that if Radeon X1000 family supported HDCP as ATi stated in their web site. The answer is yes, but not now. Radeon X1000 family actually already has build-in HDCP hardware decoding support, one could enable the function by adding Crypto ROM, yet due to the license fee, the function is disabled. ATi hints that they will releasing the HDCP version soon.
