Application Pixel Shader Performance

For our last tests, we have two applications that use pixel shaders and thus GPU acceleration, Apple's Motion 1.01 and iMaginator 2.0. 

Motion is Apple's motion graphics software package and many of its effects are rendered on the GPU.  For this particular test, we use the Motion Mark RAM Preview test described here.

As is expected, the more memory bandwidth and pixel throughput that you have, the faster the test runs.  There are no real surprises here.

Next up, we have iMaginator 2.0, a image processor that uses OS X's Core Image framework to apply GPU accelerated filters and other effects to images.  For these tests, we standardized on the benchmarks introduced by Macwelt.  The three tests used basically combine a number of filters and play 200 frames of their effects with a 0-second delay between frames, timing how long they take to play back.

Test 1 performs the following filters in this order: Kaleidoscope, Bump Distortion, Bloom, Bloom, Glass Distortion, Glass Distortion, Transition: Mod.  Our test 1 is slightly different than what was introduced by Macwelt.

Test 2 does the following: Perspective Tile, Glass Distortion, Gloom, Edges, Ripple.

Test 3 does the following: Vortex Distortion, Glass Lozenge, Pinch Distortion, Gaussian Blur, Disintegrate with Mask.

With iMaginator, we see that having more pixel pipelines can really impact application performance where pixel shaders are extensively used.  If you find yourself using a lot of applications that leverage Tiger's Core Image, you may want to think about moving to a 9800 Pro, X800 or 6800 Ultra based GPU instead of the 9600 Pro. 

It is interesting to note that in Test 1, the 256MB frame buffer of the Radeon 9600 Pro Mac & PC Edition actually gave it a significant advantage over the 128MB Radeon 9600XT, despite the fact that the 9600XT has more memory bandwidth.

    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. =)
  • Avalon - Friday, August 19, 2005 - link

    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?
