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.

The example shown does not change the overall score of the card. The example shown is for the readers reference to the test, and is not what the test scored from. There may be other reasons someone may not give these tests merit, but this is not one of them. You could maybe rank on the author for this, but not the tests.mpeavid - Friday, February 10, 2006 - link
The example shown does not change the overall score of the card.But how do we know that? Take example cadence 2224. According to the text the same item is being compared, yet different frames are clearly shown. If their methadology was more concise, their text is not.
You have to be clear about this or it misleads your readers. Its like doing a 3D test using 2 different scenes to render. Anandtech uses all the same 3D scenes to render right?

Other sites did AIW 1900 reviews on January 31st. Why so long for AT? Did ATI pass you over on sending a sample?fishbits - Friday, February 10, 2006 - link
By adding more polys, textures, particles, lights, shadows and shaders. You really didn't know this? Call any respected game dev house and ask them if they could possibly come up with a use for more GPU horsepower. The answer will be "Of course genius, we've got code and models we're waiting for capable hardware to run on, it's been that way for years. We'll take every bit of it we can get." Tell Anand I want you to spend this weekend benching EQ2 maxed out and tell us Monday if "we" still "aren't sure."
Anyhow, sounds like a nice card, but I'd rather have a more dedicated gaming card and a seperate TV tuner solution.

Of course they want more power so they dont have to write efficient and optimized code. Especially your EQ2 example comes to mind. There are far too few companies that come up with highly optimized code that will run top notch on current hardware and provide extra eye candy on future generations.Backslider - Friday, February 10, 2006 - link
The 7800GT used in the test must be stock. The one I purchased came overclocked and performs much better than what the benchmarks are showing.ATI is still too pricy at the moment, I looked up and down for an X1800XL that could come with in price range of the 7800GT that I purchased, and I couldn't find one. I wasn't going to pay $60 over when they perform so identical. The prices were approx.
X1800XL 256 Stock $330
7800GT 256 OC $270
ATI get those prices down.

I sold my 7800GTX bought a x1900XT and i couldn't be happier :! if G71 fixes some issues like IQ and HDR with AA then i will sell my X1900XT and buy a 7900GTX :) or eles wait for R6XX and G8X.Backslider - Friday, February 10, 2006 - link
Having owned an X800xl and a 7800GT, I honestly didn't see an IQ difference. The whole HDR with AA thing, well, you must play a lot of Far Cry.Good luck with keeping up with the latest and greatest though, it's almost a game with in it self. If you sell at the right times, you can upgrade for very little and still have the newest toys.
Happy gaming

I have a ati 9700 and geforce 6600gt and ati rendering look better.There are some annoying layers/plates on the nvidia rendering that i dont like.
And just one note: the display is the same on both cards.
DeathByDuke - Friday, February 10, 2006 - link
I'd certainly buy one if it was around $299-349, considering it performs closer to a much more expensive X1800XT
