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.

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.

    I've also noticed that having the steam client running in the background can place quite a load on your entire system! After downloading all the content to cut down on network/disk/buffering wierdness I did some tests benchmarking UT2004 with the ons_dria demo from nvnews and noticed that my fps drops up to 10 when steam is running in the background!

    Might it be possible to compare performance between the retail version of Half-life 2 and the steamed version available for internet purchase to see if there's any sort of performance difference? Or does the retail version just run through an offline steam client anyway? (I bought over web)

    if your game crashes when switching to fullscreen it is because you have refresh overrides in place.

    add:
    -width X -refresh Y

    to your command line, for example
    -width 1024 -refresh 100

    it fixxed all my video problems.

    #10 - That's a pretty stupid thing to say. Kyle used the cards that his readers were most likely to buy; I know I wouldn't waste my money on a non-BFG nVidia 68xx card, and I know most other gamers wouldn't either. It's a part of [H]'s focus on doing real-world-style benches instead of OMG LETZ C IF NV RULZ ATI 2DAY IN HL2!!111111

    With all that said, it's great to see stiff competition in the video card arena, finally--should make for exciting product lines on the next go-round.

    HL2 World is reporting that they've found a working Half-Life 2 multiplayer built in to standard retail HL2. Here's the story, including how to do it:
    Here's how:
    net_start
    sv_lan 0
    deathmatch 1
    maxplayers (whatever you want)
    map (mapname)
    restart
    It will add you to the master server and it works. I know, it looks like the leak, but I assure you this is the retail HL2.
    They have a screenshot, as well as a test map for you to check out if interested. Head on over to HL2 World for the full story.

    Get back to Half-Life 2? Why? There's no point other than the fact it's a pretty single player game. If I wanted single player than I would have raved about Max Payne 2, which I didn't. Why Valve didn't think to make a Half-Life 2 MP side is beyond me. That's where the market is these days. Single player games, you play them once and you are done. Multiplayer is always changing. I don't want to wait for any stupid MP mod either. Curse you, Valve, for making us wait a year longer and then only giving us one piece of the cake!

    you do realize that the fx5900 is default directx 8.1 right? if u think its beautiful now...try a directx 9.0 card =)

    I'm glad I didn't read this article before actually playing HL2.

    My system:
    P4 3.4GHz, 2GB Ram
    5900 Ultra video card
    ASUS P4P800 Motherboard

    I was playing HL2 at 1280x1024 with 6xAA, and 16xAnitropic Filtering, with everything else turned on to maximum. Besides a half-second stutter just after loading a new level, the game played GREAT, looked GREAT.

    Then again, maybe I'm not expecting the world, but, I can say that I was pleased, and maybe the x800 or 6800 can turn out better numbers, HOWEVER, at no time did I feel that I needed (or even wanted in the slightest) faster frame rates, or smoother gameplay. It just owned from the beginning to the end.

    Anand, In light of the significant ATI X800XT DX9 (HL2) performance over the nVIDIA 6800 Ultra, would you today favor the X800XT PE graphic card in combination with the MSI K8N Neo2 motherboard? In your last High-End Buyers Guide (30 August) you recommended the nVIDIA 6800 Ultra be used with the MSI K8N Neo2 because Wesley thought that motherboard performed "a bit better" with a nVIDIA card. What would your recommendation be today? Can we anticipate another High-End Buyers Guide this month(its been 3 months)? Bill

    I know, I know, but if gf2 can play at 800*600 MQ than maybe they can handle 1024*768...that would mean that a bunch of my friends wouldn't have to upgrade from their $60 cards, and they would be overjoyed :)
