Doom 3 1.3 Performance



Unlike most of the other games we're looking at, Doom 3 actually places quite a strain on the memory bandwidth of the graphics card. This seems to be the a common occurrence with many of the OpenGL games, though Doom 3 more so than others. The reason for this is the large number of stencil calculations that are required for the real time shadows. This allows the 6800U SLI setup to actually outperform a single 7800GTX by a sizeable margin - remember that the difference in memory bandwidth between a 6800U and a 7800GTX is only 9%. We also see that antialiasing has a major impact on the single 7800GTX, though it still maintains a commanding lead (25 to 81% depending on resolution and settings) over the 6800U. In the SLI configurations, the 7800GTX only leads by 15% at 1600x1200 4xAA, but that grows to 61% when we move to 2048x1536.

Switching to the ATI card, we can see that ATI has done a lot to close the performance gap in Doom 3. While the 6800U still wins in 1600x1200, the ATI card actually comes out ahead at 2048x1536. Like we've seen in a few other games, though, the NVIDIA drivers don't seem to handle 2048x1536 very well. With AA/AF enabled, the 6800U once again takes a 50% performance hit when increasing the resolution. Due to the dark atmosphere and lighting flashes, Doom 3 is a game that definitely needs to run at a high refresh rate or with VSYNC enabled, so again the lack of performance at 2048x1536 isn't the end of the world. What we're mostly concerned with is taxing the hardware to show future potential, and it's safe to say that the 7800GTX - particularly with SLI - will be able to handle all games for many years.

    Does this card play Riddick smoothly @ shader 2++ ?????

    "In aboot 5 years i figure we'll be paying 1000 bucks for a video card. These prices are getting out of control, every generation is more expensive then the last. Dont make me switch to consoles damnit."

    Funny, I can't afford the very best TVs the minute they come out. Same for stereo components. But I don't cry about it and threaten "Don't make me switch to learning the ukelele and putting on my own puppet shows to entertain myself!" Every time a better component comes out, it means I get a price reduction and feature upgrade on the items that are affordable/justifiable for my budget.

    Seriously, where does the sense of entitlement come from? Do these people think they should be able to download top-of-the-line graphics cards through BitTorrent? Do they walk around Best Buy cursing out staff, manufacturers and customers for being so cruel as to buy and sell big-ass plasma TVs?

    On second thought, get your console and give up PC gaming. That way you can stop being miserable, and we can stop being miserable hearing about your misery.

    Funny how the single card deltas here are higher than at any other site.

    Unwhelmed for the amount of money and lack of performance increase.

    Have to commend nVIDIA for ensuring retail availability at launch.

    Impressive, but I'm still happy with my X800 XL purchase for only $179. For what it seems, with a 1280x1024 display, I won't need the kind of power this card delivers for a very long time. And less than $200 compared to $600, with still excellent peformance for now and the forseeable future? Hmm, I'll take the former.

    I would have liked some 1280x1024 benchmarks with 8xAA from the nVidia cards and 6xAA from ATi to see if it's worth getting something like a 7800GTX with 17/19" LCD's to run som esuper high quality settings in terms of AA/AF.

    I'm not disappointed. For one thing the price of current cards will likely drop now, and there will also be mid-range parts soon to choose from. I think the transparency AA is a good idea for say... World of Warcraft. The game is loaded with them and too often can you see the blockyness of trees/grass/whatever.

    #44 - Actually are you new to the market? :) I remember when early "accelerated" VGA cards were nearly $1000. Or more.

    Everybody lambasted NVIDIA last year for the lack of product (6800GT/Ultra) to the market, so them actually making a presence this year instead of a paper launch should also be commended. Of course, now what is ATI gonna pull out of its hat?

    The screenshot shows very clearly that SSAA provides quite a quality improvement over no AA

    The difference is bloody miniscule, perhaps if you used an image SLIGHTLY larger than 640x480 to highlight the difference?

    Wowzers. Time to get rid of teh 9800...

    Hell, for the same price as an SLI setup I can go out and get a 23 inch cinema display...And since these cards can't handle the 30" native resolution anyway, it's a win-win. And yeah, whats up with the quality control on these benchmarks! I mean really, I almost decided to wait for the ATI next-gen part when I saw this (GeForce man since the GeForce2 GTS!)
