ATI All-In-Wonder HD, A Legend Returns
HQV Video Quality and Power Consumption

HQV is comprised of a sampling of SD video clips and test patterns that have been specifically designed to evaluate a variety of interlaced video signal processing tasks, including decoding, de-interlacing, motion correction, noise reduction, film cadence detection, and detail enhancement. As each clip is played, the viewer is required to "score" the image based on a predetermined set of criteria. The numbers listed below are the sum of the scores for each section. We played the HQV DVD using the latest version of Cyberlink's PowerDVD 8 Deluxe, with hardware acceleration for AMD AVIVO HD and NVIDIA PureVideo HD extensions enabled.
Since the Sapphire HD 3650 is based on the same technology as the All-In-Wonder HD, we left this card out of the HQV testing, choosing to focus on a direct comparison with the GeForce 8600 GTS for reference. We found the overall performance of the All-In-Wonder HD to be on the same level as the GeForce 8600 GTS. All lines were sharp, details were excellent and noise reduction was significant. The only area where the two card didn't earn top scores were with the Jaggies 2 test.

Our results show that the All-In-Wonder HD used 4 watts more than the overclocked Sapphire HD 3650 when idle and 5 watts more under full GPU load. The GeForce 8600 GTS was the most power hungry of the three, idling 1w higher and posting 20w more than the All-In-Wonder HD's loaded results.
Another test we performed was to see the impact of the various tuners on power. Below we logged the peak wattage when the All-In-Wonder HD was cycled through its video and radio content.

What we essentially see is an increase in power consumption as image quality demands increase. Overall, this shows the relatively low power demands of the All-In-Wonder HD, as it effects overall system power draw measured at the outlet.
