NVIDIA's GeForce 7800 GTX Hits The Ground Running

Half Life 2 Performance
Half-Life 2 is arguably one of the best looking games currently available. We mentioned earlier that it stresses pixel processing power more than memory bandwidth on the graphics card, and we see that here. While enabling AA/AF does cause a performance loss at these high resolutions, it isn't truly severe until we reach 2048x1536. Assuming a more common resolution of 1600x1200 - not everyone has a monitor with support for higher resolutions - the single 7800GTX is actually faster than 6800U SLI. In fact, the only time we see the 6800 SLI setup win out is when we run 4xAA/8xAF at 2048x1536, and then it's only by 3%. Also worth noting is that while SLI helps out the 6800 series quite a bit (provided you have a fast CPU and are running a high resolution), the 7800GTX is clearly running into CPU limitations. Our FX-55 can't push any of the cards past the 142 FPS mark regardless of resolution.ATI has done well in HL2 since its release, and that trend continues. The SLI configurations (other than the 6600GT) all surpass the performance of the X850XTPE, but it does come out ahead of the 6800U in a single card match - it's as much as 42% faster when we look at the 1600x1200 AA/AF scores. The 7800GTX, of course, manages to beat it quite easily. The 540 MHz core clock of the XTPE is quite impressive in the pixel shader heavy HL2, but with the additional pipelines and improved MADD functionality, the 7800GTX chews up HL2 rocks and spits out Combine gravel.
One thing that isn't immediately clear is why the 6800U cards have difficulties supporting the 2048x1536 resolution in some games. Performance drops by almost half when switching from 1600x1200 to 2048x1536, so either there's a driver problem or the 6800U simply doesn't do well with the demands of HL2 at such resolutions. There are 63% more pixels at 2048x1536 compared to 1600x1200, so it's rather shocking to see a performance decrease larger than this amount. We would venture to guess that it's a matter of priorities: the number of people that actually run 2048x1536 resolution in games is very small in comparison to the total number of gamers, and with most cards only providing a 60Hz refresh rate at that resolution, many don't worry too much about gaming performance.

Face it, this launch isn't gonna hurt anyone except people with minds too small to accept that there is simply one more option than there was before. If you liked pc gaming yesterday, then there is no reason why this launch should make you stop liking it today. Unless you're a retarded buttbaby who can't handle choices. In that case please get a console and stop coming to this site.mlittl3 - Wednesday, June 22, 2005 - link
#82, WesleyWell that sucks that ya'll have lost your web editor for awhile. Especially when there is so much cool hardware coming out around now. In our research lab, we pass around our publications and conference posters to others in the group so that a fresh pair of eyes see them before they go live or to the journal editor. But of course, everyone else at AT is also busy so oh well.
Good work guys and I look forward to the "new CPU speed bump" article (or FX-57 for those not under NDAs).
Mark
PS. If ya'll have an opening for another web editor, you should hire #84 (ironchefmorimoto). I hear he can cook really well.

Nicely corrected Derek, I think there are just a few typos left, like this one (**):Page 20
Power Consumption
We measured power consumption between the power supply and the wall. This multiplies essentially amplifies any differences in power draw because the powersupply is not 100% efficient. Ideally we would measure power draw of the card, but it is very difficult **determine** to determine the power draw from both the PCIe bus and the 12V molex connector.
AND a few double "Performances" in the title (Performance Performance) starting with page 10.
Nice card nVidia!!! I hope ATi isn't too far behind though. Crossfire --> cheap SLi ;-) I need a nice midrange product out by September when it'll be time to upgrade to a nice E6 stepping S939 A64 and something to take the place of my sweet old GF2 MX (I'm not kidding, I sold my 6600GT AGP, and now I'm waiting for the right time to move to PCIe).

Amen -- you guys work hard on your articles. Keep up the great work. And don't f*cking bother the web editor. We...er...they don't get enough vacation as it is.IronChefMorimoto

Derek was too modest to mention this in his comments, but I think you should know all the facts. 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.The next thing is NDA's and launches. We are always under the gun for launches, and lead times seem to get shorter and shorter. Derek was floating questions and graphs last night at 3 to 4 AM with an NDA of 9AM. Doing 21 pages of meaningful commentary in a short time frame, then having to code it in HTML (when someone else normally handles that task), is not as easy as it might appear.
I 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. If you see errors please email the Editor of the article instead of making it the end of the world in these comments. I assure you we will fix what is wrong. That approach, given the short staff, would be a help to all of us. We all want to bring you the information and quality reviews you want and expect from AnandTech.

#79 -- But why wouldn't it be a high quality article, mlittl3? I thought you told me that AT was infallible? Hmmm? ;-)Houdani - Wednesday, June 22, 2005 - link
Thanks for the refresh, Derek. I went back and took a peek at the revised graphs. I have a couple of comments on this article before you move on to the next project.>> When the Splinter Cell page was refreshed, the graph for 20x15x4 apparently disappeared.
>> When you removed the SLI's from the Guild War page, it looks like the 7800GTX changed from 50.5 to 55.1 (which is the score previously given to the 6800 Ultra SLI).
>> Several of the pages have scores for no AA benches listed first, while other pages have scores for the 4xAA listed first. While the titles for the graphs are correct, it's a little easier to read when you stay consistent in the ordering. This is a pretty minor nit-pick, though.
>> Thanks for updating the transparency images to include mouseover switches ... quite handy.

"They priced themselves into an extremely small market, and effectively made their 6800 series the second tier performance cards without really dropping the price on them. I'm not going to get one, but I do wonder how this will affect the company's bottom line."The 6800s were "priced into an extremely small market." How'd that line turn out? I don't imagine they've released this product with the intention of losing money overall. Why do you think retailers bought them? Because they know the cards won't sell and they're happy to take the loss? It's already been proven that people will pay for you to develop and sell a $300, wait $400, wait $500 video card. It's already been proven that people will pay a $100+ premium for cards that are incrementally better, not just a generation better. Sounds like this target is a natural, especially knowing it'll eventually fall into everyone else's purchasing ability.
Being able to say you have the bar-none best card out there by leaps and bounds is certainly worth something. Look at all the fanboys that are out there. Every week or month you're able to stay on top of the benches means you get more people who'll swear by your products no matter what for years to come. Everyone you can entice into buying your card who sees it as a good product will buy your brand in the future as a preference, all other options being equal. I could be wrong, but suspect Nvidia's going to make money off this just fine.

See... that's why I'm a big fan of the site.

#78, I bet you didn't even read the article. How do you know it demonstrated editoral integrity?IronChefMoto - Wednesday, June 22, 2005 - link
#23 (mlittl3) still can't pronounce "Penske" and "terran" right, regardless of the great editorial integrity demonstrated by the AT team today. Thanks!
