AMD's 690G/V Series Chipset Preview And Performance Testing
HQV Benchmark - DVD Video Quality
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 InterVideo's WinDVD 8 Platinum Suite, with hardware acceleration enabled.
While the tests are very specific, they require the viewer to deliver each score based on certain criteria, so they actually can be somewhat subjective in the end. However, every effort was made to be consistent with our scoring wherever possible.
In general, after scoring the R690G's performance, we found that our results were slightly higher than what AMD scored in internal testing, but we were in the same ballpark. The main difference was with the Picture Detail test, where we felt both the X1250 and NVIDIA's 6150 looked excellent. AMD gave themselves a 5 here, but according to HQV's specific directions on scoring this test we granted them (and NVIDIA) a score of 10. The rest of the test results with the X1250 were on target with AMD's own assessments.
As we stated in the beginning of the benchmarking segment, the GeForce 6150 has a PureVideo engine integrated, so this is the closest competitor to the Radeon X1250 with AVIVO technology here. With no PureVideo engine, the GeForce 6100 proved to be the worst performer, as expected.
In essence, we felt the NVIDIA GeForce 6150 offered a better video quality experience overall. Both Jaggie tests and the Flag test offered some degree of correction with the PureVideo engine and there seemed to be more activity in the noise levels in the noise reduction tests with the X1250. In the end, the Radeon x1250 with AVIVO did a fair job at improving image quality overall, but PureVideo appeared to be slightly better at this point in time.
