Arrow what does this claim imply? (ATI/nVidia)

"At the same time he confirmed that his firm was selling some X1900 XTX cards but not that aggressively. They think that X1900XTX deserves much more attention as it is winning at least half of the benchmarks, has 10 bit colour, features Avivo and can do FSAA and HDR, and Nvidia can't do these things."

what does this claim imply? can anyone explain the terms and impy how they are not available in nvidia cards??

Avivo, as far as I know, is a programming interface designed to allow the ATi GPU to rip, render and do general media encoding. It is exclusive to ATi.

As for 10bit colour, I'm not entirely sure what you are on about.

X1k GPUs can Render AA with HDR active, nVidia's currently can't.

10-bit colour could be reference to something similar to the tech on the Matrox Parhelia 512, which is capable of displaying each channel in 10-bit, meaning that 1,073,741,824 colors can be displayed simultaneously. Normally for each value of red, green and blue in a VGA signal, there are only 8 bits per value available meaning around 16 million colours.

yup seems to all have been covered.
10bit colour is the same as the top end matrox card in doing 10bits per channel which gives 30bit in total compared to 24bit of most other graphics cards.
avivio is hardware accelerated media encoding / decoding upto h.264 codec
and yes the fsaa and hdr comment is relating to the fact it can do them both at the same time, all features the nvidia 7k's cant do

I can't beleive you guys haven't got it yet...ATI IS better than nVidia. I said it a long time ago 2006 was thier year to shine...ending further DX9 gpu introduction, with the fastest gpu on the market. Sad thing is that it's mem-bandwidth limited, and only because of the cost of GDDR4. I truly hoped that this mem tech would have made it before Vista, but oh well.

Yea dude, ATI ownz0rs 2 TH4 M4XX0r.

I've been really pwning it up, trying to get XGL to work on the X800Pro in my linux box. Really good drivers those! And my 3d desktop looks ... well its a blank screen, because it doesnt work.

But gee, that black is a really nice black!

Linux on X1000s is even better. I don't have one to try, but word on the street is that it can send you bald in a matter of hours!

Plays games better. uh, they are gamer cards, after all, and nothing else. The lack of Linux Support should clue ya in a bit...

uh, anyway, DSIO, i was talking high-end, a la R580/G71.

Don't blame the hardware for software issues...

Actually, I think he was blaming the VENDOR for the software issues, and ATI is the one who has to write the Linux drivers, and either refuses to do so, or writes such crap that they are nearly unusable, anyway. But, to be fair, the linux desktop market is so freaking small that it probably is completely irrelevant to ATI at this point. Kindof a chicken and egg thing, tho.....

Not to me it isn't. The engineer's deserve the credit for the hardware; the company for letting the software developers falter. There's a big difference as to who the real people to blame are.

I blamed ATI, not their engineers

Of course, we could always

10bits (instead of 8) could be useful if you adjust gamma, brightness and contrast digitally (in the cards driver) or you´ll end up with posterized colors due to lack of dynamic range otherwise. Then again, I would consider this a really small problem most of the time....

I agree with Dsio on the Driver side (ATi). Even in Windows they are sometimes a bit flaky on new games (happens on Nvidia too but not as often), but its not as bad as it once was. Generally I have the feeling that Nvidias stuff just works no matter what platform you boot up while on ATis you can get bald real quick.

Nvidia cranks out every drop in thier drivers, ATI not so much. I'm really going to stay out of this as I still don't like ATI, in my opinion the only thing better they have is a lower price. The HDR/FSAA isn't an issue yet. People also semm to forget the fact that the real moneys in the mid range not the enthusiest class.

exacly. However my plasma supports that and it's something I would like from nvidia.

Again, AVIVO can help deinterlacing, but that's an issue that's much more of an analog issue.

I'm not mad keen on the dithering that AVIVO will do if you connect a display that can only do 8bit colour per channel though.
