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.

    I don't see the use for a video card that is cross-platform compatible, except in the corporate environment....yet it seems like this would be a good direction for future cards...which, now that I think of it, will be a moot point being that Mac is going x86...

    A side note though...
    Wow, there is a "gamer" base for the Macs? With framerates like 44 fps from their highest performing systems, I feel for them! Come on over the the x86 side, we'll take good care of you...

    I also don't understand why ATi is launching such product @ this time...It seems (my opinion) that they are bringing us backward, unless you can provide me with some rationale.

    The dual link functionality is why. Only other card for mac was the 6800 and that was very expensive.

    If someone can afford a 30" Cinema display to utilize the dual link capability, they can splurge on a 6800DDL over this card.

    Unless they have a G4 and want to use the 30" in it. Then the 6800 wouldn't be compatible. Only the new Mac Radoen 9600 Pro.

    "As a card, the Radeon 9600 Pro Mac & PC Edition is an excellent offering."

    LoL.

    It may as well NOT support PC's since no pc owner in their right mind should choose this '£200' oldie over something like a 9800pro/6600gt/800gt
  • a2daj - Friday, August 19, 2005 - link

    And how many of those "9800pro/6600gt/800gt" cards offer a dual-link DVI connector to run the 30" cinema display?

    There are many mac users looking for an upgrade in video cards to take advantage of the new graphic abilities in the new Tiger OS software. (similar to what Vista is now announcing and will be included in subsequent beta versions). A 9600 card is just what the Mac doctor ordered. So I guess ATi is looking to provide a similar card for Window users who just want to get all the graphic features Vista can provide but not interested in gaming. If they keep the price low it will be a good seller

    yes! I've always wanted to buy graphics cards 3-4 years after everyone else has had a chance to stress test them...

    funny thing is that I just upgraded from my 9600 Pro to a 6800GT :)

    Wow, a review of a three year old GPU.
    My guess is that Anand had to give ATI a good suck in order to get 520 parts before launch.
