Video Playback Quality
The HQV benchmarks from Silicon Optix are among the few available tools for evaluating playback quality, but there is one drawback about them. The tester’s perception is always subjective. Therefore you should note take these benchmarks as the final truth.
Moreover, ATI and Nvidia are constantly optimizing video settings in their drivers, so the playback quality in general and the HQV HD result in particular has improved considerably over the last year. Unfortunately, both companies take the HQV test less seriously as is indicated by the lower results.
The score of 91 out of 130 possible points is satisfactory. The Radeon ND 4550 delivers satisfactory playback quality with SD content. However, it is not as good as the other solutions, particularly the Radeon HD 3300, the integrated graphics core of the AMD 790GX chipset. ATI’s programmers must have not had enough time yet to find the optimal settings of the Avivo HD video-processor for ordinary DVDs.
High-definition video playback is getting more important because video content in standard resolution is dying out while HTPC users are likely to use a full-HD TV-set with a resolution of 1920x1080.
As you can see, the Radeon HD 4550 scores 100 out of 100 points which is higher than the opponents or integrated graphics processors can score in this test.
