Bitstreaming TrueHD/DTS-HD MA: Yep, Here too

The Radeon HD 5870 was the first graphics card to properly support bitstreaming of high definition Blu-ray audio codecs. Clarkdale/Arrandale is the second.

These CPUs come with an on-package GPU and that GPU supports the appropriate protected audio path to enable bitstreaming of Dolby TrueHD and DTS-HD MA. Of course 8-channel LPCM output is also still an option.

If you remember the G45 launch, Intel had serious issues enabling 8-channel LPCM output, HDCP and H.264 decode acceleration in general. I grilled Intel on what was going to make this round different and they are much more confident in their abilities.

They've increased the number of receivers they test with (originally it was at a whopping two, now they're up to…7). They've also expanded their test scenarios as well. The combination of the two, Intel believes, will result in a fully functional set of HTPC features at launch.

The first time I went by Intel's Clarkdale demo, Intel couldn't get bitstreaming working. A day later I got an email telling me to drop by again - they fixed it.

I got to see TrueHD bitstreaming from a Clarkdale system to a Sony receiver. I also confirmed that full two stream decode acceleration was working:

Intel had it working with Arcsoft's player, but is working with all of the major software vendors to hopefully enable full support on everything. Intel does seem to be taking this much more seriously than with G45.

The Clarkdale launch is still a couple of months away so there is definitely time for Intel to work out the kinks.

This is a serious feature. The fact is that in a couple of years every single PC shipped will have the ability to bitstream these audio codecs without any additional hardware. We're finally getting there folks.

    Dual core CPUs in 2010, AFTER we've had quad core for three generations, and even have a fairly reasonably priced Core i7 in NOTEBOOKS now? Boooooring! Reply

    Hi,
    anybody know when Intel will add support for USB 3 and SATA 6 GB? And most important in which chipset/platform will be ?
    Thanks.

    Once again AMD will be getting my money as I'm not being forced to buy two motherboards to get the CPU that I want now (Clarkdale) and it's immediate successor.

    I'm sure you're gutted.

    what PSU was being used? Reply

    I hope that mini-ITX is < 100$. I'll finally be able to upgrade from my existing atom board and its measly 2 SATA ports. Reply

    Exactly. Personally I am excited by this. I need to build a couple of things for the home network

    1. HTPC - this needs to be very very quiet. This new CPU and Mini ITX board looks spot on if (and it is a big if) Intel actually delivers on HD acceleration for both video and audio

    2. Small home server to replace the ancient thing currently flogging its guts out. This looks close - low power is good but I have two big requirements. (a) standard PCI slot for my RAID card which is an 8 port SATA raid card (Broadcomm) which just works exactly as it should. (b) with all the HD streams 2 xGb ethernet ports would be nice to allow for future expansion (and yes I know it is overkill). Looks like the current minim-itx board fails on both

    An 8 port SATA controller is very limited via standard PCI.

    Even a PCI-E x1 slot would double the bandwidth (x4 or or x8 would be better)

    Just use one of the mini-ITX boards that has a PCI-E x16 slot and check a PCI-E sata controller in there.

    Am I the only one who finds the tock-tick thingy retarded?

    It's the wrong sequence, dammit! It's like an army going 3-4-1-2 fer chrissakes!

    Okay, how is this the wrong sequence?

    They optimize the circuit design, from a known good/working design, then they optimize it at the smallest current size possible.

    How is this retarded?

    I'd guess he is arguing that the tick should be the new microarchitecture, and the tock should be the shrink of that. Reply
