HQV Benchmark 2.0 Analysis – ATi, nVidia and Intel

Last updated on June 21st, 2010 at 08:39 am

This third chapter focuses on Full HD resolution test patterns to test the scaling and filtering ability of the video processor.

We It is important when doing these tests to ensure that scaling is disabled both on any panels and in the driver software. Luminance Frequency Bands appear as alternating black and white stripes. The higher the frequency the thinner the stripes will be.

The Chrominance Frequency Test also consists of sets of horizontal and vertical frequency bands. Since this is a chrominance test, the lines are orange and blue instead of black and white.

Ideally, both sets of frequency bands should appear as a series of increasingly thinner lines. The lines in each frequency box should form a uniform pattern, evenly spaced with no artifacts or distoration.

Chrominance Frequency Bands (Score either 5, 2 or 0)
Uniform and full amplitude on all bands and without ringing or ghosting of the lines outside the pattern. – Scores 5
Some non-uniform or attenuation only on the highest band or mild faint ringing or ghosting. – Scores 2
Some non-uniformity or attenuation on any bands or heavy ringing or ghosting. – Scores 0

The Intel X4500 handles this Chrominance test better than the Luminance test on the last page. The G210 and G220 again exhibit some mild ghosting.
