NVIDIA's GeForce 7800 GTX Hits The Ground Running

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.As we can see, the GeForce 7800 GTX delivers on it's promise of higer performance at lower power due to the 110nm manufacturing process. We can't wait to see what NVIDIA's mobile division has planned for this.

oops posted before i wrote anything. Some of the results are impressive, others aren't at all. In fact results seem to be all over the board - I suspect drivers are something of the culprit and are to be blamed. Hopefully, as new drivers come out we'll see some performance increases or at least more a uniform distribution of good resultsDiasper - Wednesday, June 22, 2005 - link

Derek get cracking, the graphs are all messed up! And the Transparency AA Performance section could use some info on what game it is tested on and some more comments. I also think that each benchmark warrants some comments for all of us that have a hard time remembering two numbers at the same time. Keep it simple folks….Johnmcl7 - Wednesday, June 22, 2005 - link
I agree something is wrong with these results, I thought they were odd but when I got to the Enemy Territory ones they seem completely wrong - at 2048x1536 and 4xAA the X850XT is apparently getting 104 fps, while the 6800 Ultra gets 48.3 and the SLI 6800 Ultras are only getting 34.6 fps! Especially bearing in mind it's an OpenGL game.John

This has got to be an error by Anandtech, all other reviews show the 7800GTX in SLI at those same settings hammering the 6800Ultra in SLI.Lonyo - Wednesday, June 22, 2005 - link
The benchmarks are all a load of crap it seems.Check the Wolfenstein benchmarks.
The X850XT goes from 74fps @ 1600x1200 w/4xAA to 103fps @ 2048x1536 w/4xAA
A 33% increase when the res gets turned up. Good one.
There also seem to be many other similar things which look like errors, but they could just be crappy nVidia drivers, or something wrong with SLI profiles.
Who knows, but there's definately a lot of things which look VERY odd/suspicious here.

My Iiyama VMP 454 does 2048 no prob so i'm game :pvanish - Wednesday, June 22, 2005 - link
oh and in several of the benchmarks, the 6800U SLI more than doubles the performance over the single 6800U. Is that normal? I thought SLI gains were generally about 45% or so.rimshot - Wednesday, June 22, 2005 - link
Is it just me or is it a little strange that the 6800Ultra SLI outperforms the 7800GTX SLI at 1600x1200 with 4xAA in every benchmark ???PrinceXizor - Wednesday, June 22, 2005 - link
No comment on the fact that in virtually every game it LOSES to the 6800 SLI at 1600x1200 at 4XAA.All other scores look very impressive. But, in this particualar group of settings, the 6800 SLI eats it for lunch.
