ATI Radeon HD 5800, 5700 and 5600 Series Thread: Supporting HD Audio Bitstreaming!

Anandtech made a hint about bitstreming in the azuntech review. Something about not having to wait to long before its intergrated into graphics.

Could it be that the 5000 series support PAP?

nevermind

Iam very excited to see the idle power consumption of the 56xx series. Propably it comes with GDDR5. I would bet that idle power consumption is around 6W.

Renexth, maybe it is worth to have a bandwidth column...

Hopefully a fanless/heatsink without additional power native HDMI version will be available soon

My question is will the driver's DirectShow audio renderer support the WAVEFORMATEXTENSIBLE_IEC61937 format?

Yeah, that's the plan.

Yup. If they implement support into the driver. The Xonar did not not support the extentions on their DirectShow renderers (I was hoping they did). I don't know if the Auzen offering does or not (my wife would kill me if I tried to spend any more money just to see).

If the new ATI cards support the extention, you won't be able to sell a used Asus or Auzentech for the cost of shipping.

ffdshow tryouts supported the extentions for a while but they have been removed since no cards worked and it couldn't be tested. I also have my own "test" filter ready. (Test meaning it doesn't actually bitstream but just checks if the renderer supports the extentions. I'll add the rest once a card supports them.)

I coded an audio "decoder" filter that, when connected to a TrueHD source from either the MPC demux or the ArcSoft demux, will set it's output pin for TrueHD bitstreaming according to that developer document. If it connects to the audio renderer, the renderer supports that extention. If the renderer does not connect, then the extention is not supported.

I've tested with the Xonar and, just for kicks, the 4760. Neither supported it (I didn't expect the 4670 to though).

Short of using a decoder that supports the extention, there is no real way to test.

I wonder how James is planning to make Slyplayer bitstream with 4000 cards.

In any case, it would also be interesting to see how the HDMI device shows up on the Windows panel, and if WASAPI exclusive works as well (or better) as the 4000 series. Unfortunately this card is too expensive for me, I'll have to wait at least until the 5750.

As long as PDVD9 (or 10 for the matter) is required to bitstream I'll stick to the TMT3/HDAV solution.

Isn't there still a problem with ATI cards passing proper 24p? Renethx, I think your guide indicates as much. I thought NVIDIA's cards could do 24p but were inferior to ATI in SD processing? Am I reading your charts incorrectly?

Thanks,
Alex

I'm curious to see how the 5850 will fare against 4890. Probably more powerful, but I'm interested in seeing if it will be cooler and, thus, potentially less noisy.

This is great opfully other software players (arcsoft)? will offer bitstreaming over the ATI 5xxx families.

IF so then in Q1 I will get rid off my Asus slim whenthe first 5650 or 5670 that could be made fanless will show up.


This is really cool.

this is great !!!!

now... lets hope slysoft SLYPLAYER will also support this card... :-)

That Eyefinity version only has 1GB which is not listed on the graph above.

Dammit, I just bought a HDAV Slim.

Here's hoping Gigabyte makes a 5850 fanless version with the same cooler as their 4850 version.

I am more a purpose driven guy. As you might know I got a Standard and Slim HDAV and it is doing exactly what I want with my native HDMI fanless 4670 these days. It will be nice to combine both together and I am sure that is what I will end up doing that. But there is no rush for me, both of them are silent and take less power then the about release 5XXX not to mention it probably got a QA cycle for us They can count on me for Q1 for sure but not like the 4850 again!

i have a question about the bitstreaming. My understanding is that the older cards (4350, 4550, 4650, etc) do support bitstreaming of these sound formats (DTS-HD and TrueHD MA) but at a lower bit rate (this due to no PAP). Am I wrong about that?

wow, that's awesome =). 2bad i just bought 4890 =(.

gonna have to wait til 6xxx series to upgrade =).

nextguy, previous gens do NOT support bitstream at all whatsoever. they support bitstream converted to LPCM 7.1, but only at 24-bit/48kHz because of non-PAP. there are certain discs w/24-bit 96kHz, but it's quite rare.

either way, the true bitstream is a welcome since there ain't no limitations now on LPCM either, u can now also do 24/96 on LPCM.

They're not supposed to support (at least officially) bitstreaming of THD and DTS MA at any bitrate. There was some confusion caused by some poor wording on ATI's site, but these 4000 cards are not bandwidth limited in any way. The limiting goes on in the player. These cards are capable of full 8-channel 192 kHz 24-bit audio output through HDMI (36.864 Mbps).
