AnandTech takes a closer look at the UVD debacle with the Radeon HD 2900 XT graphics card:
There has been a lot of talk over the past week about the fact that the Radeon HD 2900 XT lacks UVD (Universal Video Decode) hardware for HD video decode acceleration on the GPU. We've seen sites from The Tech Report to DailyTech, and even Beyond3D reporting on the situation. While there is much discussion already out there, we would like to provide our take on things.
To recap, the situation is as follows. A huge number of press and channel partners were given the impression by AMD that their R600 GPU used to build the new Radeon HD 2900 XT contained UVD hardware. AMD's press materials are incredibly vague about the issue: they never explicitly state that the HD 2900 XT does or does not physically have UVD hardware. They do list R600 as having AVIVO HD, which they explained includes GPU offload of the entire video decode pipeline in their press materials.
