HQV Mixed 3:2 Film With Added Video Titles Test
These tests are meant to see how well the video processor handles mixed film and video. Basically the test show video footage with a moving text overlay traveling first horizontally and then vertically. If processed incorrectly, jagged edges can be seen on either the moving text or the background image. Both ATI and NVIDIA scored the same here, and both seemed to have a slight problem with jagged edges on the background image. But they each did a good job with the moving text.
The main issue that each solution had with the horizontal scrolling is seen on the guitar strings. The strings should look smoother than they do, and the notches indicate a problem correctly deinterlacing the video.

You have identical numbers for w/ AA and w/o. Also, the text's comment on the X1900AIW being playable at all reolutions with AA uses the incorrect numbers.plonk420 - Friday, February 10, 2006 - link
does the ATI decoder give you the option to ADD sharpening? or not at all? my whole reason for wanting a (hardware accellerated) software decoder is so i can have a pic quality rivaling a ("popular") $200 hardware player for whatever extra it would be for the software. supposedly free for ATI or $30 for nVidia (for my application: 2.0 sound)hwhacker - Friday, February 10, 2006 - link

590/684...I was close.
18+% improvement in 3dmark06, you know that has to translate to something good in gaming.

It uses 2.0ns chips from what I recall, as does newer BBA x1800xl's (instead of 1.4ns).There was one site that did an overclocking section on it, I forget which. The results were similar to x1800xl's, the end clock speed ending up 600+/almost 700 iirc. You know how XL's clock, i'm sure.
So in essence, yes, it overclocks well, and I do remember the site being amazed by the performance improvement through overclocking. I still don't get how 2.0ns chips can hit 1.4ns speeds if there is a speed bin in-between for cards like nvidia's 7800gt/gtx that you would think use that supply...but i've seen quite a few cards with the newer, slower, chips hitting the same approx speeds as the old ones with 1.4ns, and i'm not complaining. ;)
I'm sure with the overclock or ATiTool soft-vmods this thing would be killer, especially with better cooling than the known-for-sucking XL stock cooler.

What I'm curious to know is whether the AIW can overclock to roughly XT/XTX speeds.What type of RAM does the AIW use?

Agreed. How can AT not include this? Lame.DigitalFreak - Friday, February 10, 2006 - link
Although I appreciate the DVD decoder tests, how is this review related to the AIW features of the card?highlandsun - Friday, February 10, 2006 - link
I would have been more interested in seeing how well it handled H.264 decoding at 1920x1080p.oxid - Friday, February 10, 2006 - link
does the 7800 gt use another video processor then the GTX? because in the last review with the HQV tests the 7800 gtx scored better then the gt in this review...mpeavid - Friday, February 10, 2006 - link
You guys need to use the exact same frame as an example for all cadence tests. Not doing so can invalidate your test.
