NVIDIA's GeForce 7800 GTX Hits The Ground Running

Wolfenstein: Enemy Territory Performance
As an older OpenGL game that lacks any fragment programs (OpenGL's equivalent of DirectX Pixel and Vertex Shaders), most of these setups breeze through it, even at high resolutions like 2048x1536. The only setup that doesn't provide smooth frame rates with AA/AF enabled is the 6600GT. There is clearly a problem with the SLI support in Wolfenstein 3D, as both the 6800U and 7800GTX both run slower in SLI mode than in single card mode. We would assume that the 6600GT SLI is also failing to take advantage of the second card, so the relatively low frame rates in AA/AF mode are due to driver problems more than anything. Also of note is that despite the lack of advanced pixel effects, Wolf3D is relatively CPU limited. 120 FPS even with an FX-55 appears to be the maximum.The one noticeable advantage of the 7800GTX is that it makes 2048x1536 4xAA a truly playable resolution, even for competitive online gamers. The speedup at 1600x1200 4xAA is only 18%, but 2048x1536 runs almost 50% faster. If you have a monitor capable of running such a resolution, the 7800GTX is one of the few cards that can actually handle it. When (or perhaps if) NVIDIA fixes the SLI support for Wolf3D, we should also see acceptable frame rates out of the SLI setups even at the maximum resolution, though given the popularity of the game we have to wonder why NVIDIA hasn't already included proper SLI support.
The ATI side of the equation is once again lacking. While it is more or less able to match the 6800U, ATI clearly has no current answer to the 7800GTX. We'll have to see if Crossfire does better with accelerating Wolf3D than SLI. If it does, we expect NVIDIA to suddenly find the impetus to actually get SLI support working properly.

"NVIDIA sees texture bandwidth as outweighing color and z bandwidth in the not too distant future." That was a quote from the article after saying that Nvidia was focusing less on Memory Bandwidth.Do these two statements not match or is there something I'm not aware of.

These benchmarks are pretty clearly rushed out and wrong, or at least improperly attributed to the wrong hardware. SLI 6800 show up faster than SLI 7800's in many benchmarks, in some cases much more than doubling single 6800 scores. I understand NDAs suck with the limited amount of time to produce a review, but I'd rather it have not been posted until the afternoon than ignore the benchmarks section.IronChefMoto - Wednesday, June 22, 2005 - link
#28 -- Mlittl3 can't pronounce Penske or terran properly, and he's giving out grammar advice? Sad. ;)SDA - Wednesday, June 22, 2005 - link
QUESTIONOkay, allcaps=obnoxious. But I do have a question. How was system power consumption measured? That is, was the draw of the computer at the wall measured, or was the draw on the PSU measured? In other words, did you measure how much power the PSU drew from the wall or how much power the components drew from the PSU?

Wow, I'm simply amazed. I said to someone as soon as I saw this "Wow, now I feel bad that I just bought a 6800GT ... but at least they won't be available for 1 or 2 months." Then I look and see that retailers already have them! I was shocked to say the least.RyDogg1 - Wednesday, June 22, 2005 - link
But my question was "who," was buying them. I'm a hardware goon as much as the next guy, but everyone knows that in 6-12 months, the next gen is out and price is lower on these. I mean the benches are presenting comparisons with cards that according to the article are close to a year old. Obviously some sucker lays down the cash because the "premium," price is way too high for a common consumer.Maybe this one of the factors that will lead to the Xbox360/PS3 becoming the new gaming standard as opposed to the Video Card market pushing the envelope.

What no Crossfire benchies? I guess they didn't wany Nvidia to loose on their big launch day.Lonyo - Wednesday, June 22, 2005 - link
The initial 6800U's cost lots because of price gouging.They were in very limited supply, so people hiked up the prices.
The MSRP of these cards is $600, and they are available.
MSRP of the 6800U's was $500, the sellers then inflated prices.

#24: In the Wolfenstein graph they obviously reversed the 7800 GTX SLI with the Radeon.They only reveresed a couple of labels here and there, chill out. It's still VERY OBVIOUS which card is which just by looking at the performance!
WAKE UP SLEEPY HEADS.

Derek,I know this article must have been rushed out but it needs EXTREME proofreading. As many have said in the other comments above, the results need to be carefully gone over to get the right numbers in the right place.
There is no way that the ATI card can go from just under 75 fps at 1600x1200 to over 100 fps at 2048x1535 in Enemy Territory.
Also, the Final Words heading is part of the paragraph text instead of a bold heading above it.
There are other grammatical errors too but those aren't as important as the erroneous data. Plus, a little analysis of each of the benchmark results for each game would be nice but not necessary.
Please go over each graph and make sure the numbers are right.
