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, 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 Zino 410 was able to get.

To put this score in context, let us look at the HQV 2.0 scores obtained in some of our earlier tests.

HQV 2.0 Benchmark Scores

Amongst SFF HTPCs, the Zino 410 undoubtedly has the best HQV score. However, it is unable to approach the high scores obtained by the desktop 5570. Note that the Zino 410 is able to achieve this because none of the other GPUs have proper cadence detection (which forms a bulk of the score).

Unless the end usage scenario involves heavy viewing of streams needing cadence detection, it is hard to recommend the Zino 410's Mobility 5450 on the basis of the HQV scores.

    ...would having two differently-sized SO-DIMMs have on system performance?

    I'd be tempted to take replace that 4GB module with a 2GB one just to see what happens. 6GB of RAM just doesn't compute. :)

    We seem to be getting a decent number of Dell-AMD systems lately... I only hope they take up Brazos with the same level of enthusiasm, because even if it did result in a small drop in performance, this review would've been largely the same in terms of gaming and video playback/quality, albeit with a much smaller footprint. Also, in that scenario, dual channel wouldn't matter as Fusion doesn't support it.

    If AMD has anything like Intels asynchronous dual channel, the first 4 GB will perform like dual channel, whilst the remaining 2 GB will perform like single channel.

    Dual-channel memory was a scam from the beginning that has somehow survived to this day to make PC buyers think they needed to buy more memory than needed.

    Have you seen the benchmarks? ~1-2% benefit AT MOST for anything that's not a synthetic memory bandwidth test, regardless of platform.

    Didn't it help back in the P4 and/or P-M days? And how did it do in early Athlon 64 days?

    But yeah, Core Duo and newer doesn't really benefit from Dual channel, one
  • silverblue - Saturday, February 19, 2011 - link

    Theoretically, dual channel would help APUs as they're bandwidth-limited.

    I suppose you're right about standard usage though, even raising memory clocks doesn't make for a sizeable performance advantage.

    Starcraft 2 is not a synthetic memory test, and it does benefit from going from 2 to three channels, just read some performance reviews of Starcraft 2.

    The einstien@home applications benefitted from a 3rd channel on i7 quad cores; and the 2nd channel on C2 quads as well; high performance server farms/clusters/super computers are a significant segment of the market. On the i7-quad, E@H had a 66% speedup from the 2nd channel, and a 5% gain from the 3rd. Sandybridge gave a similar speedup from the 2nd channel. I can't find the thread with the C2Quad results, but IIRC they were a 10-25% speedup.

    I don't have benchmarks handy, but I suspect a heavily loaded DB server would also benefit from the extra memory bandwidth because the queries would result in a psudorandom memory access pattern that would limit the ability of the cache controller to prefetch most of the data being requested.

    that actually had to do with uncore clocks, not memory channels.

    How would a Mac Mini compare?
    Could a Mac Mini be retrofitted with a Blu-Ray drive (since Blu-Ray is available factory installed) and then run as a Windows HTPC?
  • tipoo - Saturday, February 19, 2011 - link

    Why on earth would you buy a Mini to run as a Windows HTPC? You'd pay more for less performance.
