Zotac's Ion: The World's First mini-ITX Ion Board

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.

Thanks Anand, will definitely drop you a note regarding this over the weekend. It's quite unfortunate that Zotac left out Wake-On-USB for their 9300/9400 mobos, something many consider essential in an HTPC build.djc208 - Tuesday, May 12, 2009 - link
If I didn't have so many projects already I'd seriously consider one of these as the basis of a CarPC system. It's not cheap but a good touchscreen car monitor will run you far more.NNix - Tuesday, May 12, 2009 - link
On page 5: "Once more, the Pentium 4 gets beat by the Atom 330 but loses to the Atom 230"I hope you will review Cortex A8-based Netbooks once they show up. Because Im not impressed at all with Atom, not when looking at <45W dualcore Athlons. Taking into account that those are at 65nm aswell the Atom aint looking that efficient.

I would take a Celeron 420 any day of the week over an Atom or a dualcore athlon ;)GaryJohnson - Tuesday, May 12, 2009 - link

"Celery is for eating, not computing."Sorry, let me be perfectly clear, I would like a Core2 Conroe-L from 1.6-2.0 ghz (every one I have used will easily go over 3 ghz with no voltage increase)
Look at the raw numbers between the Atom and the Conroe-L and tell me on a desktop/stationary machine (IE not a netbook) you wouldn't rather have something more than twice as powerful.
I realize it is called a "celeron", but it is the most freaking powerful (Core2 architecture) Celeron ever sold.
They cost $25-35 on ebay, the LGA 775 version of this board is only $139. It makes a whole lot of sense if you don't plan on running it on battery power.
Not to mention you can move all the way up to a Quad if you want, but a $60 e5200 2.5ghz 2MB Level 2 Cache seems like a perfect match.
Oh, and you get a PCI-e 2.0 X16 slot :P http://www.newegg.com/Product/Product.aspx?Item=N8...">http://www.newegg.com/Product/Product.aspx?Item=N8...
For $10 more it makes a whole lot of sense. (If you already have the LGA 775 chip laying around it makes even more sense.)

What could have made this board perfect is a PCI-E slot to stick some decent audio in. Anyone seen mini PCI-E sound cards around :)Visual - Wednesday, May 13, 2009 - link
Why would you want a sound card for any computer made in the last 10 years? Even with the fanciest card, there would not be even one bit of difference on the digital outputs, which are the ones you should be connecting to your receiver. On the analog outputs there will be quality differences indeed, but if you're using them you deserve what you get :p Besides, I get the feeling you wouldn't notice the difference anyway as if you're that stupid to be using them you are also probably using some crappy speakers.flipmode - Tuesday, May 12, 2009 - link
"Everyone seemed to want a Ion based motherboard after I first previewed the platform."Yeah, it is all because of you :roll:
Is that x264 encoding that you used to test power consumption? Why that? The most power draw likely comes from the chipset. Test Blu-Ray playback or something.

The first comment was pretty rude and uncalled for, I must say.I wanted to see an Ion-based HTPC after the preview and this article confirmed that an Ion-based HTPC is what I should set my sights on next. The only improvement Zotac could have made is to include a PCIe slot for TV tuners, audio, or beefed up video. A higher rated Atom would be nice too, but I don't even know that one exists.
