Head to Head: ATI Radeon X800 XT vs. NVIDIA GeForce 6800 Ultra

For our first head to head comparison we have ATI's top of the line X800 XT against NVIDIA's flagship GeForce 6800 Ultra.

At lower resolutions the performance is close in our first demo, but as we crank up the resolution and turn on AA, the X800 XT pulls ahead:

The X800 XT continues to maintain a significant lead at higher resolutions with AA enaabled:

In our final test the X800 XT only really separates itself from the 6800 Ultra at 1280 x 1024 and 1600 x 1200 with AA enabled.

X800 XT

What the X800 XT holds over the 6800 Ultra is a 10 - 20% performance advantage in high resolution AA performance, but at lower resolutions and with AA disabled the performance is very similar between the two.

    yawn, i'm too busy enjoy the game (6800gt) to read the article and/or care which card is better :) i'm playing at 1600x1200 0AA/4AF (2.4@3.3/1GB) and have absolutely no complaints, other then knowing that the game will eventually end :(

    #57... poorly :)

    I would also like to to see how the 9200/9000 series Radeons perform too, and if you have extra time, the 8500/9100.

    Again, Thanks!
  • Jeff7181 - Thursday, November 18, 2004 - link

    #16... that's correct, although the only REAL observation that needs to be made is that Half Life 2 makes heavy use of pixel shaders which is very GPU dependant, and GPU's are just now growing the required testicles to process those shaders :)

    I would like to see how the 6600 performs. As an 8 pipe card, it should perform better than the 9600xt and a little under a 9700 Pro, but it would be interesting to see if that is true. It is a great budget PCIe card along with the x700.

    Thanks!

    nice review downloaded your demos to run on AMD64 3700+ @ 12x 222 = 2664mhz with 1GB BH-5 @ 222mhz 2-2-2-6 1T and Powercolor X800XT PE @ 520/560 and all demo results were within 3-4fps of the reviews :)

    Good reading as always. Would like to see minimum FPS tough. I find it very important to see how low the cards drop when stressed. You can't see that with only average FPS.

    So... wheres the Nvidia SLI versus ATI results??

    Muwahahaha.

    Hey Anand, I have an interesting request. Could you try Rivatuner on your 6800, unlock its pipes, and then bench it again? :P
    Just kidding. Actually, I'm glad you've confirmed what I've been thinking...that AF hasn't been doing much for me. Since I'm running on a lowly 9700, I think I'll just turn it off now, and enjoy a nice speed boost.

    How about throwing a GF 5600 and maybe even a GF 5200 in as well for part 2, as an awful lot of people have them. Ultra versions of either if you prefer.

    I don't have one of them myself as I'm still using a Ti4200, but it would be interesting to see how they stacked up in the DX8 codepath against the Ti4600 you are planning to test. And it should be worth a giggle to see just how "fast" the 5600 or 5200 can manage the DX9 codepath :)

    Thanks to the resolution scaling-graphs this review included and how the fastest cards were generally CPU limited with that A64 4000+ when the resolution was dropped to 1024x768, I'm not sure how much a CPU scaling article for part 3 will show that can't already be quite accurately guesstimated from how different CPUs generally tend to perform in games. But a comparison of the Athlon 64 4000+, against an Athlon XP, a Prescott, a Northwood, and if time permits a fast P3, Duron and Celeron also, would be great.
