HD Video Quality: HQV 2.0 Benchmark

Now we test the ability of these cards to deliver high-definition video quality using the HQV 2.0 benchmark:

While the Radeon HD 5670 cannot handle mosquito noise reduction without dropped frames, the new 6570 and 6670 can. This means that the pinnacle of AMD's video image quality (a score of 201, according to the HQV 2.0 benchmark) starts at the ~$80 Radeon HD 6570, and more expensive Radeons offer nothing better. This is a significant improvement over the GeForce lineup, where the top-scoring cards achieve about 160 points.

When you consider that all of these reference cards are half-height models without dedicated PCIe power connectors, you can see that the Radeon HD 6570 and 6670 have a lot of potential to be excellent HTPC graphics cards.
