Zotac’s Ion in My Theater

Last year I spent a lot of time building a home theater. All content is played back on my HTPC running Windows Vista Media Center along with MyMovies (to catalog my library) and VMC Media Browser to tidy up the interface. The hardware is composed of an ATI Radeon HD 4550 as well as an Intel Core 2 Quad Q9650. The result works pretty well. I wanted to see how close the Zotac Ion could get to my setup.

With an external power supply I didn’t have to do much, I just grabbed the Zotac board and the power brick, set the two on top of my equipment rack and plugged it in. I immediately appreciated the silence of the Zotac, as quiet as I’ve made my HTPC, it’s still not totally silent. That doesn’t usually matter while I’m watching a movie, but whenever I pick the seat closest to the equipment rack it irks me a bit (similar to how you can always notice even the most minor scratches on your car).

Actual video playback wasn’t an issue, the Zotac board already passed all of my Blu-ray tests if you’d remember. And I rip all of my content so CPU usage never even went beyond 20%. What I wanted to know was how well the Zotac board could handle navigating through my library, the VMC menus, etc...

I for sure thought that the Atom was too slow to serve as a real HTPC. Sure you could watch movies on it, but actually navigating through your library using a pretty UI - no way.

I must admit, I was pleasantly surprised.

The Zotac Ion was by no means fast at navigating through the Media Browser interface, but it was acceptable. Scrolling through tens of movies is a bit painful, make it hundreds and you may want to consider a faster CPU, but it wasn’t nearly as bad as I expected.


The VMC Media Browser interface, slow, but usable on the Ion

During playback I could pause, skip forward and adjust volume without dropping any frames. The Ion worked as a real HTPC doing real duty. I was impressed. Pair it up with a TB hard drive and you have a great way of watching your content on your TV or projector. Use a NAS and you can even keep all the noise out of your theater room.

Performance aside, remember that this is a GeForce 9300 we’re talking about here. I had a single HDMI cable going to my receiver which carried 1080p video, DD or DTS 5.1 audio or 8-channel LPCM if I decided to let my machine do all of the decoding. I didn’t test CPU utilization on the latter due to time constraints but I plan to in the near future.

    I need a ITX with PCI-e 1x slot. ANyone seen such an animal?

    @Pandamonium,
    No it was not rude; flipmode was obviously joking about the funny sounding line in the article.
    Lighten up...

    Yeah, it did sound pretty rude, but I was just giving him a hard time.

    I didn't intend for the line to sound like that, I meant that after our first review went up there was a great amount of interest in an Ion motherboard from our readership. I'll update to clarify.

    I stuck with the x264 test for power consumption since we've used it in previous reviews and I needed a good way of comparing power consumption to other systems that can't play back Blu-ray content.

    Take care,

    I did not mean to sound too snotty, but I do enjoy being a smart ass once in a while. Maybe a :wink: would have been better than a :roll:

    As for power consumption, using x264 encoding does make sense for most reviews, but it seems a bit of stretch for this one. I sure do feel bad for anyone encoding x264 with an Atom. Do you think it is safe to say that the power consumption would be at its highest when the IGP is under load?
  • Anand Lal Shimpi - Tuesday, May 12, 2009 - link

    I agree, in hindsight I should've probably done a load test with the GPU being stressed as well. I'll try and look at that if I do a followup.

    The power consumption of the Ion/GF9300 chipset should be higher than the dual-core Atom CPU, so anything that stresses the GPU should deliver the highest power consumption. Note that Blu-ray playback uses the PureVideo HD engine which is actually separate from the shader processors on the GPU, it's a separate set of functional blocks on the die. I wouldn't assume that BD playback would generate the highest power consumption values, playing a game might do the trick for that.

    Take care,

    Anand, Thanks much for the review. I have been wondering much about this platform since I first read the ads on nVidias webpages.

    Here, we live off grid, and are entirely powered by solar + wind (and the occasional running of a 30kW gen to pump water). What I was hoping to see here, was something that could play games fairly well at medium settings, do photoshop tasks fairly well, and play movies well also. I was fairly certain the latter would not be much of a problem, but the former two might have been. According to your benchmarks, it looks like my guess was not too far off.

    Also, your review came about two days too late concerning a decisions I was making concerning getting a newer system for above duties, while keeping power usage down to a minimum. That however is not your fault, and probably made my decision much easier.

    Now, I would like to add that the Zotac board with ATX power connectors is it ? May actually be a better overall option for some, including myself, *if* "we" can find a good sub 100W 80 Plus PSU. Once you get down to around 50-60W of system usage, the 50% PSU power out/usage combination is what can, and does kill power efficiency according to what I have been reading(e.g. for best efficiency, loading any PSU is usually optimal at 50% load capacity). George Oui from ZDNET tech articles (sorry may have spelled his last name incorrectly, I do not have the link handy) has done some experimentation on the subject, and at the time of his findings the best PSU he was able to find was the sparkle 220W 80 Plus PSU ( the PicoPSU's did not seem to do as well ). Anyways, he was able to get a complete Core 2 system, including an LCD monitor down to a sipping 49W of power usage while under load I believe. Personally, I consider that pretty good.

    Anyways, thanks again, and I for one would love to see more articles along these lines.

    Why not simply run something downclocked? Low-power parts or simply a laptop with a discrete GPU is also a possibility. Or even something like the Fujitsu Amilo Sa 3650 with graphic booster (external mobile HD3870).

    BTW the Zotac board comes with a powersupply and doesn't have an ATX connector in this version Anand reviewed.

    The Pico-PSU efficiency is going to be rather dependent on the efficiency of your AC to DC conversion. They claim over 95% DC-DC efficiency, so if you have an efficient method of directly feeding them regulated 12V they probably do pretty well. I suppose if you needed multiple workstations you could use one ATX PSU to feed regulated 12V to a bunch of Pico-PSUs and get the load on the ATX PSU up to the range it likes. Otherwise, I'm not sure how efficient those bricks are at Ac to DC.

    Great review, thanks!

    Speaking of GPU tests, I have seen other reviews of Ion showing Left 4 Dead playable at 25fps and WoW (720p, low details) playable at 50fps! How come your rates are so low?

    I think it would be appropriate to follow up with testing of games like UT2004, Halo PC, COD4, Battlefield 2, and Counter-Strike: Source. Obviously, Crysis would be a waste of time on this platform, but some slightly older games that are still played heavily online and at LAN parties are ones I would really like to see benched.

    Nothing would excite me more than to have a portable, cheap, fanless, low-power, Mini-ITX gaming machine for some of the games listed above. If it can manage 25-30fps at or near 720p without looking like a turd, that would be more than acceptable. Please don't make me buy one and benchmark it myself! ;-)
