NVIDIA's GeForce 7800 GTX Hits The Ground Running

Transparency AA Performance
For our Transparency AA testing, we ran through the AT_Canals_08-rev7 timedemo in Half Life 2. This demo has quite a few fences, and we wanted to test NVIDIA's claim that graphical quality is indeed improved significantly. Our performance tests show that MSAA comes at a marginal performance hit to overall framerate, while SSAA consumes quite a bit of our performance.
In order to illustrate the effect of the new AA mode, we took screenshots of a tell tale frame from our demo run. The screenshot shows very clearly that SSAA provides quite a quality improvement over no AA. MSAA ends up not looking worth the investment.

SS Transparency AA
Below we have prepared some mouse overs to demonstrate the difference between the various levels of Transparency Anti Aliasing. Put your mouse over the first image to see the difference betweeen no Transparency AA and SSAA. The second image compares no AA with MSAA and the final image compares SSAA to MSAA.

The difference between no Transparency AA and MSAA is very small. Only with a difference map are we even able to distinguish between the two. However, the difference between MSAA and SSAA is very pronounced.

#114Dude just stfu......we are here to comment what we want and say it freely......minus threats and name calling....as i said before this card is not for gamers...maybe elite gamers that have a monitor that does these resolutions but most gamers i know have went to lcd and i have yet to see any lcd[im sure there are some]do these resolutions so this card really is a card for crt elite gamers......lol with those resolutions on a 21 inch monitor you would need binoculars as glasses to play the game....the tanks on bf2 would be ant like small....

#114I am SO glad that Anand remains in business despite all the bitches that are in these comment sections.

Those who are complaining that they should have reviewed at lower resolutions should think for a minute. First of all you are talking about a 600 buck card, most people who have that kind of money to spend on a card also have a monitor that is capable of 1600x1200 or better. Also benchmarking at any lower resolution on a card like this in todays games is almost pointless as you are almost entirely CPU bound at those resolutions. Do you really want to see page after page of 1024x768 charts that differ by only 4-5 percent at the most?Also give the editors a break when it comes to writing these articles. As others have said this is not a subscription site and given the number of visitors and the quality of the articles I'm amazed, and gratified, that the people of Anandtech keep putting out article after long article despite all the winning that goes on over spelling mistakes and graph errors that more often than not are corrected within a few hours.

That's a really great comparison, #112, especially seeing as how we pay for AnandTech and any problems with it could leave us stranded in the middle of nowhere. And so witty, too!Jarred, ah, thanks.

"Our Web Editor is on vacation and we are all doing our own HTML and editing for the next 10 days. In our usual process, the article goes from an Editor to the Web Editor who codes the article, checks the grammar, and checks for obvious content errors. Those steps are not in the loop right now."" do know Derek as a very conscientious Editor and I would ask that you please give him, and the rest of us, a little slack this next week and a half"
Dear Mr. Fink,
I am sorry to hear about the problems you have had with your vehicle breakdowns. You see, our quality inspector was on vacation that week, so we just shipped our vehicles strait off the assembly line. Please cut us a little slack, as we usually build much better vehicles.
Sincerly,
Buncha Crap,

my question is how did they do hi res 2048x1536 when the card is only single-link DVI? Shouldn't either an analog connection or dual-link be necessary?yacoub - Thursday, June 23, 2005 - link
#108 - what do you want, a $2000 CPU to go with your $1200 in GPUs? =PCtK - Thursday, June 23, 2005 - link
so dual display is still not available with dual 7800s?!?!?!?!?smn198 - Thursday, June 23, 2005 - link
Come on Intel & AMD. Keep up!
