HQV

DVD playback depends on a lot of factors. In the HQV test, we test out the graphics card in various aspects of video Noise reduction, Film Cadence etc. A total score of 130 if the card passes all the various tests. Here is a breakdown of the score.

The ATI HD Radeon 2900XT exhibits better noise reduction than the 8800GTX but didn't detect 3:2 promptly. In the rest of the tests, both cards perform equally well for video.

Temperature Monitoring

As there are no applications are available to read off the GPU temperature, we used the most traditional method. We attached our multimetre's temperature probe to the metal plate of the graphics card. We recorded the before and ater scores of the graphics card. The test is conducted in a room of an average 28 deg ambient room temperature.

We let the card to stabilise as we don't run any 3D applications. The recorded temperature is 42 Deg Celsius. After that, we began running 3Dmark05 which is more GPU intensive. At the end of the test, the recorded temperature is 53 deg celsius.

We did the same thing again, this time round, we connect the probe to the exhaust of the graphics card. The temperatures before and after are 50 deg celsius and 55 deg celsius.

Considering a plus minus of 5 deg, we would expect the GPU to reach around 60 degrees under intense usage.

Note that these readings are taken off with mainboard and graphics card in open air.
