Blu-ray Done Right: How Does Your Integrated GPU Stack Up?

Image-Quality: HQV’s High-Definition Video Benchmark, Cont'd

Film-Resolution Loss Test: Out of 25 points

This test shows a pattern of lines and color bars. If the hardware can show the smallest lines without flickering, it is successfully de-interlacing the image. This is an important feature, as many movies and television shows are shot at 1080p24, and successful film resolution compensation will display a superior, de-interlaced image.

Here the Intel G45 was incapable of proper inverse telecine in our test system, even though it should be capable of handling this feature. The Radeon and GeForce chipsets coped with the test admirably, but the GeForce 8200 must use the older 182.5 driver in order to work. Since film resolution is something most users are likely to come across during movie playback, this is an important test.

Update:As documented on page five, we did manage to get Film Mode Detection to work on the G45 chipset, earning it a full 25 points in this test.

Film-Resolution Loss Stadium Test: Out of 10 points

This test shows a video of a stadium captured on film. If there are no visual artifacts, then there is no resolution loss.

Once again, the Intel G45 isn't able to handle film-resolution loss even though it is supposed to possess the feature, while the Radeon and GeForce chipsets are doing a great job of processing the video. Once again, the GeForce 8200 required the older 182.5 driver in order to succeed at this test.

Update:As documented on page five, we did manage to get Film Mode Detection to work on the G45 chipset, earning it a full 10 points in this test.

Now that we’ve examined the specific tests, let’s have a look at the totals:

These results are definitely encouraging for home-theater buffs, especially when you consider that our HQV tests last year yielded zero points for the 780G and GeForce 8200. Clearly the driver technology has come a long way for AMD, Intel, and Nvidia. 

Even the Intel G45 musters a decent score, and while it doesn't make the grade when it comes to the important film-resolution loss tests, it does a good job of noise cancellation and interlaced video processing.

Update: With Film Mode Detection now working, the Intel G45 board scores an impressive 90 total points.

The GeForce 8200 was the biggest disappointment. Even though it achieved a decent score, it did not have enough graphics horsepower to run without stuttering when the noise reduction feature was used.
Without the noise-reduction feature enabled, the GeForce 8200 has a realistic total score of 55 -- much less impressive.

    Great article. I think maybe the 4650 is a bit overkill, but that's just nitpicking.

    As long as you are talking about HTPC builds though, you might want to mention temps... aren't the 9300/9400 boards very hot?
  • epsiloneri
    Power draw is not interesting because of the electricity bill, it is the generated heat needed to be dissipated with the associated noise levels due to cooling that is critical for an HTPC.

    i don't get it why a home theater would use a 1200w power source. at the same time i don't get why would someone evaluate the power efficency using this kind of power sorce. if you ask me i'd make this crazy ass power supplies illegal. a normal hometheater should not use more than 50w at idle and 100-150w at load. seems that this is what these actually consume. factor in the less than 5% load on the power supply and you get a masterfull 50-60% power efficency. i'd love to see some proper power supply test.

    BTW, I would like to see a "Can it play Crysis" article in the future that runs down every video card and IGP, then determines if it can possibly play Crysis and at what settings.

    the 1200w power supply is green as in blue-green mould green.
    this is in fact an excellent power supply... if you use it. at 100watts load it has a "cool" 76% efficency. if the intel pc uses less than 82watts in load and 66watts in idle you can only imagine the efficency a power supply has at below 5% load. the site suggest around 65% so instead of having a proper power supply using 40watts or less when idle, you get this "green" efficient hummer who swollows 66w. i really like you articles guys but this kind of testing is not the way to go.
  • Efficiency isn't even tested below 20% load i believe But it should still be around 70-80% it is a Thermaltake Toughpower 1200w and all of them(3 listed on their site) are standard 80% eff rated or bronze. Ture a more modest Delta,Seasonic 250w or 300w would be much more appropriate for a htpc.
  • HalfHuman
    20% for this would be 240watts and efficency would still be reasonable.
    i posted some link but i see it's been removed. that review said something about 65% minimum.

    Uh, guys... you might want to edit this article...
    "For the last CPU utilization test, we will check the capability of these graphic chipsets to accelerate picture-in-picture (PIP) video streams. To do this, we will use the Blu-ray dick Sunshine, which utilizes the H.264 codec and features PIP commentary during playback."

    "If you are an audiophile, you should know that out of these remaining options, only the GeForce 9300/9400 can handle uncompressed eight-channel LPCM audio over HDMI 1.3."

    i did NOT know this...

    i thought only way to listen to uncompressed audio on blu-ray was using Asus Xonar HDAV 1.3 audio card to bitstream to your receiver...

    it's nice to know that IGP has enough power to handle 1080p while streaming HD audio codec....
