HQV
2.0 BENCHMARKING
HTPC
enthusiasts are often concerned about the quality of pictures output by the
system. While this is a very subjective metric, we have decided to take
as much of an objective approach as possible. Starting with the Core 100 review
in 2010, we have been using the HQV 2.0 benchmark for this purpose.
The
HQV 2.0 test suite consists of 39 different streams divided into 4 different
classes. The playback device is assigned scores for each, depending on how well
it plays the stream. Each test was repeated multiple times to ensure that
the correct score was assigned. The scoring details are available in the
testing guide on the HQV website.
In
the table below, we indicate the maximum score possible for each test, and how
much the ASRock Vision 3D 252B was able to get. As mentioned in the previous
section, we used NVIDIA Graphics Driver v301.24 for the benchmarking.

When
compared with the other SFF HTPCs, the score doesn't look out-of-place.
However,
we have seen NVIDIA GPUs scoring higher in earlier reviews. This is just an
indicator of how new driver releases tend to break existing features. As we
will see in the next section, there are a number of knobs in the driver which
just don't work at all.
