"The Radeon HD 4350 is an even cheaper alternative to adding 8-channel LPCM output and ...". Please enlighten me how 8-channel is possible on a card w/o HDMI. Are they using Magic? Or is there a way to extract it w/o HDMI? Or is the card they showed in the photo an example of a 4350 that's too-cheap to offer 8-channel? Or....
Quite possibly I missed the obvious, but I didn't find any 4350's on the ATI site to double check this. Or, perhaps this review had a bit too much sales blurb and too little testing? I agree with others who feel that if you're going to hype 8-channel and HTPC, you ought to be performing quantitative/qualitative tests.
Oh! Then... it's not a DVI-D dual-port card, despite the use of that connector?! Or, they diddle a non-data pin (like +5v for monitor stand-by) to permit both DVI-D/dp and audio? 'Spose that's too much out of an inexpensive card... Thanks for the info!
They send the audio over dvi, an adapter from ati will turn the dvi input to hdmi output w/ video + audio. I assume the retail packaging would ship with the adapter.
as usual you have some wrong numbers in the charts. the 4650/4670 have 32 texture units not 16. whats strange is that you actually corrected it in the 4670 review only to make the mistake again in these charts.
I also expect comparison of video quality between nVIDIA Ati and Intel
More explanation about video processing what does this specs mean are they possible to turn off:
Color space conversion
Chroma subsampling format conversion
Advanced vector adaptive per-pixel de-interlacing
De-blocking and noise reduction filtering
Detail enhancement
Inverse telecine (2:2 and 3:2 pull-down correction)
Bad edit correction
Automatic dynamic contrast adjustment
Full 30-bit display processing
Programmable piecewise linear gamma correction, color correction, and color space conversion
Spatial/temporal dithering provides 30-bit color quality on 24-bit and 18-bit displays
Is it possible to select the video output range 16-235 vs 0-255 manually?
I expect that there will be more in dept article for HTPC and mabe there you will explain what should we pay attention to.
Give us a screen shot comparison of the driver setting pages of the Ati nVIDIA Intel.
I want to know what settings are possible with Clear Video vs Avivo HD vs Purevideo HD.
Also about how do we select colors rec BT 601 vs rec BT 709
I would have appreciated it if they had included a video quality comparison for this new crop of HTPC cards. I made the mistake of buying a cheap 3450 for bluray, which does accelerates fine but has low image quality. It'd be useful for my next purchase if I had more to base a comparison on. Otherwise, so far it looks like the passively cooled 4550 would be a solid upgrade.
I agree - it's not a good HTPC solution if it doesn't give you the same playback quality as a high end card. You didn't test that so you can't really make a judgement, and hence have no basis for saying it is.

As Natfly mentioned, they use an adapter to transform one of the DVI ports into HDMI (with some of the DVI pins carrying audio data).It's probably the same adapter that came in the box of my 4850.

If they are DVI-D, the DVI-A pins are avaliable for use.If not, there are always unused pins, extra ground pins, etc.
