of course they play up their hardware some but look at the FEAR benchmarks. the 1800xt beats the 7800gtx by 80% in 1600x1200 4xaa, 8xaf.
3 different hdr modes. ultra high AF, 32 bit precision always on.
should be some nice cards. it seems they are pushing the 512meg cards out for cheap on the mid-high range models.

The FEAR benchmark is probably on the 512MB card. There were som Call of Duty 2 benchmarks on the X800XTPE, 7800GTX, and X800XL 512MB. The X800XL beat the other two...
I'm guessing FEAR really benefits from the extra video memory. It's not an 80% faster card by any means.

heh, now these are the marks i was expecting...
*laughs at the general direction of foo*
Psyche911 is right, i would more put it in the ballpark of a rough 20% faster card ( remember i said rough )
kinda odd though, isent the 7800GTX offered in a 512 model?

Hell, the X1600XT looks like it would offer a nice upgrade from my 9800 Pro. And it's got an MSRP of $250. Which means I can probably get one under $200. There's no way I can afford any X1800 series card. Unless there is a huge price war between the X1800XL and the 7800GT and they go below $300...and then I'm pushing it.

In time, I'm sure it will come out.
They always counter each other, whether it's on the same day or 3 months later. There will be one, I guarantee.

notice the emphasis they put on image quality without the big speed hits we are normally used to.
thats what i like, it's all about IQ.
anyways there is some new alpha texture AA modes that will be put into all r300 cards and up. things like fences, trees will get AA without a noticable performance hit. you can enable it now with ati tray tools and 5.9 drivers. looks really nice on bf2.

yea, i'm in the same boat.. i sold my old hardware ( Athlon 1800+ @ 2.0ghz, Asus A7n8x-e delux etc ) on a kinda rush, so i had to pick up a AGP based AMD 64system only because i dident want to dump another $300 for a pci-e card.
Meh, I'll Live with my 9800 pro for a little longer.

hmm, i don't think it will crush the gtx in most of the games out know. it seems to be designed for heavy shader power(fear, future games)and marketing up superior IQ.

Well, it shouldn't crush the 7800 series. They're the same generation.
The R580 shouldn't be all that far off, maybe 6 months to a year. That might crush a little, but nVidia has had some time to work on their next chips since the GTX has been out for like 2 months now.

it will be nice for consumers if ATI is really taking the ultra-iq route. nvidia will have no choice but to counter with their own ultra-iq in the future.
IQ back in the spotlight, i like.

hmm they talk about hdr and post processing AA. i wonder if that means it has some kind of memory buffer or dedicated memory like xb360 to add AA to the the final frame output with hardly any performance hit.

I wasn't aware of anything like that on a consumer PC GPU... I guess we'll see in 2 1/2 days though, eh?

nVIDEA still sounds like the market leader for openGL at least,

From what i can see from the 1800xxt, they're not that better from the 7800gt series, aparrently they have less pipelines than the original series.
Even the top the op 1800 series struggles to keep up with the 7800gt card.

There's a more lengthy discussion of this over in GD.
Basically, they're both good GPUs. But if you consider price and power consumption, nVidia's the winner in my book.

from what i've read some of the extra juice could be due to 512 ram.
and i won't discuss it anymore in gd hehe.

this is why i won't discuss it anymore. no offense dave. and the rest of you should get off the crack pipe.

Game retails, we will see real numbers..
its an ATI sell sheet.. AND the FEAR DEMO is just that, a demo which isnt optimized for EITHER card..
Happy for ATI if they actually pull it off, but until retail comes out for either of those, its just smoke up the ass..
Oh, and lets see benchmarks when they come out for the cards, and not some sell sheets made by ati..

Actually, sites are saying the FEAR demo doesn't show the final game's performance on either hardware. It's believed to even out somewhat by the time it's released.
And shadd, I've read that too, about the extra RAM causing the huge power consumption (I think 40 watts higher than the GTX?). We'll have to see what the X1800XT 256MB uses when it arrives.

woah just watched this demo from ati. it's 90 megs or so video of realtime rendering on x1800 series.
i know it's a tech demo and not too concerned if the cards can really do it in games or not. it's just a really awesome piece of work worth watching regardless if youre interested in graphics cards.

hmm, ati's x1800xt beating nvidia's 7800gtx in doomIII at 1280 rez and up with aa.
supposedly a generic openGL AA fix that fixes performance by up to 35%.
if it gets 100% verified that is.
ATI Technologies have this morning made a tool available to HEXUS which supposedly improves scores in most OpenGL games when antialiasing is enabled at high resolution. Improvements 'of up to 35%' in Doom3 are explicitly mentioned by sources within ATI. The tool seemingly changes the way the graphics card maps and accesses board memory to better deal with handling AA sample data.
As well as supporting Doom3, the tool is said to increase performance in all OpenGL titles when using antialiasing. With Doom3 the poster child for that graphics API, ATI's willingness to promote the increases in that application in particular are understandable.
The fix will shortly be rolled into CATALYST 5.11 according to ATI sources and a beta drop of that driver will be made available for testing in due course, before the final WHQL driver from Terry Makedon's CATALYST team is made available for public download in November.
