I've been considering upgrading my vid card from a Radeon 8500 lately and i only use it for movies. Then I saw this on another thread

Quote:
The Radeon 9600 should be plenty capable for such purposes. Or even a Radeon 7500 should work just as well, for DVD's.
Is it true

Well someone else on this forum (and I read elsewhere too) that the Radeon 8500 (Which I have also) doesn't do full precision somewhere in the DVD decoding process. I am not sure where buts its something like, Radeon 8500 (and I am sure 7500 and other cards below 8500) - 12bit, Radeon 9700 and above - 16bit.


I will have a look around to see can I get the exact specs but I am pretty sure you will notice a difference. I would also like to know. I wonder does it only effect hardware decoding though. I would think so.

also if one uses VMR9 and enables fsaa and AF the 9600 should have a real PQ up over the 8500.

Steve,


I'm sure Radeon 9500/9700 will beat 8500 for DVD playback.

Go get this card with MP-1 mod, you will love this combination with your CRT pj.

I'm using 9700PRO MP-1 feeding G70.

The picture is awesome. :)

With all due respect, I believe these responses are incorrect. If all you are doing is watching DVD's, you shouldn't expect any improvement over your 8500.


This has come up numerous times on this thread - do a search.

If we look at the features. All RADEON cards have the same features like below.
  • MC and iDCT
  • 10 bits DAC. Great for overlay viewing.


Known differences are:
  • 10 bits frame buffer is available on 9700, 9600, and 9800 only. Not sure about 9500. This is necessary for good VMR9 viewing because gamma and color calibration in VMR must be done in buffer level.
  • Analogue stage may be different. Some people say newer cards are more sharp. I don't know. MP-1 mod will be definitely good.
  • YUV to RGB color converting table or something like that is different, I think. IMHO, the same DVD appears differently. 7500 is warm. 8500 is bluish. 9000 is greenish.
  • Precision? I've never heard about this, but Mark mentioned about this above. So, just putting it in this list. ;)

Mike Parker (mp20748) told that 9500/9600 have difference in PQ (better) compare with previous Radeon series.

Do a search in CRT forum.
