Doom 3 Performance

The Mac version of Doom 3 was finally released, a lot later than expected, but it provides us with a truly modern game engine on which to test performance. 

Unlike the PC version, Mac Doom 3 is far less of a performer, even when paired with an X800 XT or GeForce 6800 Ultra DDL.  There's been much discussion as to why, but it looks like there are a number of factors that contribute to very poor performance of Doom 3 under OS X.  The fact of the matter is that while a GeForce 6800 Ultra would be more than capable of running Doom 3 smoothly at high frame rates on a PC, the same cannot be said even at the lowest resolutions on the Mac platform. 

We ran all tests at High Quality settings, using Doom 3's built-in demo1 timedemo. 

With our expectations appropriately set, let's look at the performance breakdown:

Doom 3 Performance

You can see that the Radeon 9600 Pro Mac & PC Edition isn't the best performer here. At 800 x 600, it can barely offer more than 20 fps.  The OEM 9600XT is about 6% faster than the 9600 Pro Mac & PC Edition, completely as a result of its 11% increase in memory bandwidth. 

What's interesting is that even the 6800 Ultra DDL never peaks above 44 fps, even at 640 x 480.  NVIDIA also continues to hold the Doom 3 performance advantage here, much like they do in the PC world.

    In the list of stores, you have "The Future Shop".

    Future Shop, a Canadian retailer similar to Best Buy (actually bought out by Best Buy a while ago), has no "the" in the name. It is simply "Future Shop".

    ATi's got to make the news headlines somehow. Now if cards were hot swappable then I could see a market for this, but currently if you use a PC and you buy this card, you might as well save the money for a session with your shrink.

    Why is this posted in the PC section again? Why would any PC user want this card?

    This sort of card isn't going to impress the gamers; but it is exactly the sort of thing that probably makes Matrox, and their ilk, really nervous. It looks like, in the next few years, pure 2d desktops won't really exist anymore, except among people who really don't care. So everyone will need a decent GPU. Also, except for hardcore cheapskates and/or the "LCDs are t37 suxx0r" crowd, a good chunk of the computer using population will being using big DVI connected panels within the next few years.

    This is pretty much the perfect card for such an application. Especially now that pretty much anything will do for all but gamers and specialized workstation tasks, the upgrade that people will want will be high resolution panels. Is this expensive by the standards of 9600s? Certainly. Is it quite cheap compared to the few other cards that can drive huge displays? Certainly.

    Did any of you bother reading the article? How many ATI or NVIDIA consumer PC offerings out there can drive an Apple 30" cinema display at the native resolution? That display reguires a dual-link DVI connector. I don't know of any other consumer level PC video card which has one. That's the main PC target.

    "That display reguires a dual-link DVI connector. I don't know of any other consumer level PC video card which has one."

    Monarch Computer has the AGP XFX GeForce 6800 128 MB DDR/8x-AGP/TV-Out/Dual-DVI (Retail Box) for $163. That makes $200 for a 9600 Pro look pretty sick.

    Dual-link DVI is different from the card having two DVI sockets.

    A dual-link DVI socket has double the bandwidth of a standard single-link DVI socket (330MHz vs 165MHz). That allows it to drive a display at a very high resolution with a normal refresh-rate.

    That XFX card has two standard single-link DVI sockets and therefore cannot be used at such high resolutions with the DVI digital connection as the 9600Pro in this review.

    I bet that NVIDIA is releasing FX 5700 Ultra Mac/PC edition very soon. =)

    Should have done this with a newer GPU. No point in this thing being PC compatible for $200.

    Humm, I find it interesting that ATI is finally releasing a cross-platform card so close to the Apple transition to x86. Considering OpenFirmware is being dropped, the Mac side of this card will have to be completely redone for the new x86 Macs, so a card like this wouldn't have much of a shelf life I would think.

    Don't ATI have anything better to do I wonder? Like saving their PC market for example?
