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

CPU-Usage Benchmarks: MPEG-2 Codec

Now we will move on to the MPEG-2 codec. As usual, we'll start with the AMD platforms:

All of the results are close, and although the GeForce 8200 has slightly higher utilization, it performs better than it did with the H.264 codec. Once again, keep in mind that the AMD solutions are also producing excellent noise cancellation in addition to low CPU utilization.

The G45 and GeForce 9300 results are neck-and-neck again.

    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?

    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.

    BUT CAN IT PLAY CRYSIS!

    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.

    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....
