HQV Benchmark 2.0 Analysis – ATi, nVidia and Intel

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

Overview:
The fourth chapter focuses on analysing the video processor’s ability to enhance the image through ‘adaptive processing’.

Notes:
The first set of results examines contrast enhancement features. These results concentrate on expansion of image contrast ratios while maintaining detail in dark and white sectors. This test is not targeting image sharpness, detail, flicker or noise, just contrast enhancement.

Scoring:
All the tests are combined into one result, giving a total figure. The score is based on evaluating the sequence of images. Note that fine detail would not be observable on small screens or displays which are not fully HD compliant.

In this particular test we look out for expansion in image contrast without the loss of fine detail in the dark areas as well as overexposure or washing out in the highlighted zones. The tree roots bear significance.

Contrast Enhancement: Driftwood (Score either  5, 2 or 0)
The overall image contrast expanded without loss of detail in the white or dark regions. – Scores 5
The overall image contrast expanded with slight loss of detail in the white or dark regions. – Scores 2
The overall image contrast expanded with moderate to high loss of detail in the white or dark regions. – Scores 0

The nVidia cards score particularly well with this specific test, as do the Intel solutions. There is a slight loss of detail with the ATi boards in the highlighted areas.
