Ion: CPU still sucks, but Blu-ray now playable

Just picked up this little tidbit from Techreport‘s review of the Zotac IONITX-A, suggesting that the advent of dual channel memory has fixed their Blu-ray playback issues. Of course non-GPU accelerated formats still suck the proverbial:

Back when we first tested the Ion platform’s Blu-ray chops, we found that playback wasn’t smooth with Nature’s Journey, a 1080i title we were playing back at 1080p. We were using PowerDVD, which is compatible with the GeForce 9400′s PureVideo HD decode block, so application acceleration wasn’t the issue. Instead, Nvidia said the stuttering we experienced was caused by the combination of the fact that PureVideo was only optimized for 1080p content and the fact that the Ion reference design had only a single memory channel. Apparently they were right, because the IONITX had no problem smoothly playing back Nature’s Journey or any of our other Blu-ray movies at 1920×1080 resolution over HDMI. In fact, CPU utilization only hovered around 30% during Blu-ray playback.

Thanks to its PureVideo HD support, PowerDVD also had no problems handling 480p, 720p, and 1080p movie trailers. The 480p and 720p clips even played back smoothly in QuickTime, which doesn’t make use of GPU acceleration. Our 1080p clip stuttered too much to be watchable, though. Speaking of stuttering, the IONITX proved incapable of handling HD YouTube content. That’s not terribly surprising considering how CPU-intensive Flash-based video playback seems to be.

They then go on to recommend the Zotac GeForce 9300-ITX WiFi with Socket 775 and PCI-E x16… which is indeed a tempting solution.

Developments, plodding along

January 15th, 2009

A few things have occured since the last postings, on both the file server and media centre fronts. I figured I should document them before I forget.

Media Centre

  • Apple did not release an updated Mac Mini, so we’re back to waiting on Nvidia’s Ion, which had some impressive demos at CES2009. Steve is a bit busy dying, so there’s obviously other things to focus on (although rumours keep on spinning).
  • XBMC 9.04, due in April, will feature not only Dolby TrueHD decode, but Blu-ray container support (M2TS/M2T/MTS) and the ability to load a file through an external player. Since Media Player Classic can run without GUI, this should work seamlessly. DTS-HD doesn’t seem to be there yet, unless it’s known under some other name I’m not aware of. Either way, a big step along the way to becoming the software of choice. We’ll have to wait and see if it’ll load the Blu-ray disc automatically though, or if you need to point it right at the M2Ts files.
  • After some reading around the net, I’ll have to test out Windows Home Server as a base OS. Otherwise at this stage to save pain it will most likely be a straight XP Professional install. While XBMC’s focus is Linux, I don’t expect easy Blu-ray playback to hit that platform any time soon.
Apparently a 2.5-inch drive can fit in the Ion reference case.

File Server

  • Zebra over at Speedlabs suggested I’d need more than 4GB RAM to make sure Windows Server 2008 virtualisation is snappy. May as well double it to 8GB!
  • Finding out if HighPoint’s RocketRaid 2340 is OpenSolaris compatible is nigh on impossible without simply buying it, even with journalist contacts. If anyone knows somebody within HighPoint, please let me know.
  • Apparently ZFS on FreeBSD is stable so long as you run the 64-bit version, and have over 1GB of RAM according to a friend who has played with it for the last year. It might have to be a reserve option.
  • Crap. I have two of these drives, and Seagate is going all Apple on there being no acknowledgment. Very, very vexing.

The only thing holding up the purchasing of equipment is finding out about the HighPoint card — so here’s hoping I can dig up the information soon.
