Blu-ray Playback: It Works Quite Well

I tried using the Zotac Ion to watch Blu-ray movies, after all, that’s one of the major reasons to get this thing over the much cheaper Intel alternative. NVIDIA’s Ion chipset (aka GeForce 9300) can fully decode H.264 and thus make high definition movies watchable on the otherwise incapable Atom CPU.

Anything that supports NVIDIA’s PureVideo HD will work on the Ion board, in this case I used Cyberlink’s PowerDVD 9 Ultra - the latest version off of Cyberlink’s website. I fired up Casino Royale and watched, the CPU utilization across all four virtual cores (two physical cores) ranged between 19 - 27% on average. At times I saw steady peaks at 36% and the highest I ever saw was 50% in an unexpectedly stressful scene. With the dual-core Atom, I never saw any dropped frames.

The high CPU utilization is simply due to the content decryption required by every copy protected Blu-ray disc, the actual decode is being done completely in hardware. If you playback an unencrypted Blu-ray disc you get CPU utilization in the 10 - 14% range.

Earlier versions of PowerDVD were not well optimized for Atom, but the latest updates to PowerDVD 8 and PowerDVD 9 ensure smooth playback on even a single-core Atom/Ion system (I used an older version of PowerDVD in my short lived Ion Blu-ray Investigation which was the cause for poor performance in those tests). Note that at one point in my testing I saw the CPU usage hit 50% on the Atom 330, which means it would be at 100% with an Atom 230. The spike only lasted for a second or two but it's possible for a single-core Atom setup to stutter in situations like that if you have a background task running at the same time.

You can even get hardware acceleration using the Ion board under Media Player Classic - Home Cinema. Using the latest stable build of MPC-HC you simply need to go to the Options menu (View -> Options) and configure a few items. Click on Output then select EVR or EVR Pres. if you want to enable subtitles.

Then click on the Internal Filters option and disable all FFmpeg transform filters, enable all DXVA transform filters and enable the Matroska source filter (for playing back MKVs).

If you configure MPC-HC as I described above you'll get full hardware acceleration on the Ion board. This is a great way of watching your own ripped content. Without encryption CPU utilization ends up being in the 10 - 14% range, allowing you to even do things in the background while you're watching a video. I would caution you against doing too much however, so much as scrolling the volume slider up/down will cause the video playback to stutter. You're probably better off just being happy that you're not dropping any frames and not touch anything while you enjoy your movie.

    The board is cool as could be. And also, the external power brick is precisely what is needed to make this thing relevant.

    I've always had a dream to build my old computer case, to build a computer that was unique in its size and look. I'm a pretty good wood worker, and I can cast simple aluminum shapes... you get where I'm going with this.

    So this obviously is the dream motherboard for that application. Making some awesome looking little computer out maple or something.

    It also hits the mark with the silent or near silent design. You add a laptop hard drive for its quiet operation and you're in business.

    I am impressed, and as an enthusiast it hits the marks. The problem is that I'm more of an enthusiast in my mind than in my purchases. I snap out of the trance and realize that for the price of the motherboard you can have a complete computer w/ a case and a warranty with a 2.2ghz core-based single core Celeron which would just about trounce this little fellow. It's not quiet and it's not tiny but I'm a looser like that. I just can't do it.

    Then again, I don't have a ton of extra cash. I can think of a million things I'd rather do with $400.00 than build a swanky looking (and silent) PC with this platform.

    This platform is ripe for the picking. It's cheap to make, and it fills a need. We need to start seeing these out in the stores in volume. Because at the end of the day, these computers could be small enough that you don't even see them. Ubuntu is also ripe for the picking (Microsoft is fine, just too expensive for these little machines IMHO).

    It is absolutely possible, to make a desirable machine out of this with 2GB of RAM and an 80+ GB hard drive for the sub $200 range. I can find some pictures of Acer's computer, but I haven't seen it at Walmart... so really, it hasn't been released yet. These products are profitable and cheap, why aren't companies making them?

    Seems to me this article shows you wasted money, and could have easily gotten away with putting an E5300 in your HTPC, or similar, and saved what? 300 dollars. Yeah, Q9650 still costs WAY too much to be a viable option, and for most uses is overkill anyway, especially for an HTPC.

    How would this compare to an Intel 1.4 Gig Celeron? I have an Intel 1.2 gig Celeron and it still runs and it runs fairly cool with a lower end power supply. This is the Celeron based on the PIII. Is the Atom processor more advanced that that?

    Why these things do not have a video input for video recording? Or I'm missing something. Thanks.

    You'll probably get better results from CoreAVC for h.264 playback (compared to MPC-HC's DXVA codec) for at least two reasons:

    1) CoreAVC is far better multithreaded than libavcodec, which MPC-HC's decoder ultimately relies on. It makes 720p h.264 generally playable on an Atom 230 even without any acceleration, and the 330 should have no issues

    2) CoreAVC recently added CUDA support, which includes the 9300 used in the Ion.

    I also recommend combining it with Haali's Renderer (comes with Haali's Splitter) and giving it a chunk of RAM for the buffer. It will buffer uncompressed frames/audio and help smooth over any spikes in CPU usage.

    I have been eyeing this one up since I knew about it. I recently built the MSI Wind PC barebones nettop single core 230 Atom. It handles 720p fine if it's not streaming, albeit the processor is loaded 90%, 1080p is not possible on the 945GC.

    The Ion will smooth over some of the issues nicely, as well the Zotac board supports up to 4GB of ram, the MSI Wind PC nettop maxes out at 2GB, though it supports x64 there isn't enough Ram available to make good use of it. The Zotac has the same processor (230) so x64 is not an issue either. DVI is nice as is the power brick.

    Newegg has two 230 mobos in stock, $149 w/o the 90w brick, and $169 with it. Not cheap, figure in $50 for 4GB of Ram, optical drive (blue ray $$$ or dvd), hdd and a case it's easily a $300-600 build for the single core 230. No pricing on the 330 yet, but I suspect it will be over $200.

    I would opt for the dual core for better performance, albeit heat and energy savings will be sacrificed. Still have to wonder justification on this, the Atom has limitations and there will be a bottleneck for sure.

    It's only $139 for a socket 775 version.

    The Celeron 420/430/440 are much more powerful than an Atom. Even if you underclock them a little.

    If you need "power brick" power investigate the PicoPSU: http://www.mini-box.com/DC-DC">http://www.mini-box.com/DC-DC

    I am sure if you want a proper mini PC you could build one on 775 (don't forget that there are 45nm processors and you can use a copper core heatsink, even a $10 OEM one from the older 65nm Quad cores will keep it running very cool).

    I would love to see the power usage back-to-back with a PicoPSU between the "Ion" and the LGA 775 platform (please choose a low-end proc like Cel 1400/1500 or e5200, and throw in a Celeron 420-440 as well). I would expect it to be 10-15 watts more, but with much more processing power.

    A few weeks ago, Anand posted an article regarding Blu-Ray playback performance issues with the Ion chipset, which was quickly taken down after Nvidia wanted time to replicate the results. Whatever happened with this? Was there some type of workaround used to fix the Blu-ray playback?

    On page 3:

    "Earlier versions of PowerDVD were not well optimized for Atom, but the latest updates to PowerDVD 8 and PowerDVD 9 ensure smooth playback on even a single-core Atom/Ion system (I used an older version of PowerDVD in my short lived Ion Blu-ray Investigation which was the cause for poor performance in those tests)"

    Since most people are using Windows XP, and especially since XP is more likely to be used on Atom based computers, it would be more meaningful to run benchmarks with XP rather than Vista. Other than that, it was a very interesting read. Good job Anand!
