Head to Head: ATI Radeon X800 Pro vs. NVIDIA GeForce 6800GT

Priced at $400 our next head to head comparison is between the 12-pip Radeon X800 Pro and the 16-pipe GeForce 6800GT.

    In map AT_coast_05.dem, GF6800U have no performance penalty with 4xAA@1024x768?

    hey, #27, I was gonna say that ;)
  • jediknight - Wednesday, November 17, 2004 - link

    Well, it's obvious from the benchmarks. They don't lie.

    ATI RULZ NVIDIA SUXORZ!!

    Do you need HL2 to play CS: Source? Thanks.
  • wien - Wednesday, November 17, 2004 - link

    #24 There is.. It's called Counter-Strike: Source
  • bob661 - Wednesday, November 17, 2004 - link

    Anyone know if there's multiplayer support in HL2? Thanks.

    Nice and thorough comparison. That 6600GT looks more and more enticing...

    Great article, looking forward to reading the next one with slower cpus. Being cpu limited with an A64 4000+ is a little scary, I wonder what kind of fps an XP3200+ gets when paired with an AGP 6600GT. (still running an overclocked Barton 2500+)

    I'm surprised at how well NV stacks up... And good to see the 6800 GT beat the X800 Pro. Not because I'm an NV fan, but simply because it makes it easier to choose. When the 6800 GT wins over the equivalent ATI card, even in an ATI-optimized game, then it's kinda easy to choose what to buy... :D
    It's a lot harder with the other cards, where both companies scores some wins in different games.

    Yeah, I'm hoping a CPU round up will come after part two! I can afford a 400 dollar video card but not paired with a 700 dollar AMD CPU.

    I did notice a lot of stuttering in my gaming experience with a A64 3000 + 6800 GT/1024 MB pC3200. I was playing at 1280x1024 with 4x/8x max details. So likely I would have to cut out the 8x Aniso to have smooth gameplay. I don't know if that was what Anand was mentioning about with the "Shimmering" of textures with the Manhatten calculations.
