Common Features


Some of the new features common to all the new GPUs (codenamed Evergreen) are:
  • Manufactured with TSMC 40 nm process or maybe even 32 nm for Redwood and Cedar (currently 55 nm process except for HD 4770/4750).
  • Support for DirectX 11.
  • Eyefinity multi-display technology, supporting up to three displays (one display must be DisplayPort or use an active DisplayPort to DVI/HDMI adapter). HD 5870 Eyefinity6 (a single GPU) even supports six displays (at least four of them must be DisplayPort).
Video and Audio Features (Check the slides posted at Hot Hardware .)

HD Video Playback Capabilities
  • Enhanced UVD 2.0: Hardware acceleration decode of dual 1080p HD video streams
  • Windows Aero Mode: Playback of HD videos in high quality with Windows Aero mode enabled
Video Enhancements
  • Video Gamma: Independent from Windows desktop for a superior user experience
  • Brighter Whites: Or "Blue Stretch" processing increases the blue value of white colors for brighter videos
  • Dynamic Video Range: Controls levels of black and white during playback
HDMI Audio Features
  • Bitstreaming Dolby TrueHD and DTS-HD Master Audio
HDMI Features
  • HDMI 1.3a Deep Color & x.v.Color
  • Over 1 billion colors output through HDMI: 12-bpc output, 10-bpc (4:4:4) meaningfully derived
  • Wide range of colors: Full support for wide-gamut xvYCC video signals
Bitstreaming HD Audio


Among them the greatest feature for HTPC users is the support for bitstreaming Dolby TrueHD/DTS-HD Master Audio over HDMI. Finally we don't have to buy an expensive HDMI sound card for this purpose, although you have to wait until Q1 2010 to get the mid-range to low-end cards HD 5670/5650 and HD 5550/5350. Meanwhile, HD 5770/5750, expected in October 23, 2009, may be a good compromise for the mainstream users (not ultra expensive, good 3D performance implies good video post-processing). If you are building a gaming HTPC however, a high-end GPU is the way to go (roughly 1.5 times 3D performance increase from the current GPUs).

AACS-Compliant Players Supporting HD Audio Bitstreaming
  • CyberLink PowerDVD 9 Ultra (Build 2320 or later)
  • Corel WinDVD Pro 2010
How about ArcSoft TotalMedia Theater? There is no official announcement, but this will also support it soon according to various posts by ArcSoft_Jason in the thread: Non-AACS Players Supporting HD Audio Bitstreaming


What about media players? Could, for example, MPC HomeCinema or the 7MC internal player output HD audio bitstreams? A key is the WAVEFORMATEXTENSIBLE_IEC61937 structure introduced in the Windows 7 SDK. This extends the WAVEFORMATEXTENSIBLE structure (introduced in Windows 2000) to describe new compressed HD audio streams such as TrueHD and DTS-HD. If the driver supports this extension, then the developer of an audio decoder (e.g. AC3Filter, ffdshow tryouts) should be able to implement HD audio bitstreaming easily. Please also read vladd's posts . Note that PAP (encrypting HD audio signals in a user-accessible bus such as the PCI Express bus) has nothing to do with HD audio bitstreaming. PAP is required only for an AACS-compliant player such as PowerDVD and TotalMedia Theater. (BTW PowerDVD uses the older WAVEFORMATEX structure to bitstream HD audio.)


An innovative way of bitstreaming HD audio is being developed by albain, an ffdshow tryouts developer (suggested also by James at SlySoft). The idea is use PCM output with right description of non-PCM data, similar to AC3/DTS in S/PDIF. This uses WAVEFORMATEXTENSIBLE_IEC61937 structure for this purpose. So far the attempt is not successful yet, but apparently this is the most promising way. If you are interested, please follow the threads:
Update (December 2, 2009)


ffdshow_rev3128_20091128_dbt_bitstream_beta42 finally succeeded in bitstreaming Dolby TrueHD. For details check

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?

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...

Finally we will be able to get a cheap solution for bitstreaming HD audio! (You need a copy of PowerDVD 9 Ultra.) But you have to wait until Q1 2010 if you want a midrange/low-end cards (HD 5670/5650/5550/5350). The following cards replacing the current HD 4770 are expected in October 23, 2009 and are relatively inexpensive:


- HD 5750: $149

- HD 5770: $199

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

If the driver suppors it, media player developers can implement HD audio bitstreaming easily, right? If so, that's an interesting question.

Yeah, that's the plan.

Now MKV files with untouched TrueHD/DTS-HD MA audio tracks would be a viable option.

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.)

BTW how do you check if the driver's DirectShow audio renderer supports the WAVEFORMATEXTENSIBLE_IEC61937 format?

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
