Quake 4 Performance

Quake 4 gives us a good performance benchmark based on the Doom 3 engine. The game looks a bit better than Doom 3, but interestingly performs about the same. Without AA enabled, NVIDIA does a little better than ATI, especially in the higher resolutions. With 4x AA, NVIDIA is still a bit better in general, but the gap closes significantly, and the Crossfire setups come out ahead of the 7800 GTX 512 SLI.

    this is where things get a little fuzzy ... when we used to refer to an architecture as being -- for instance -- 16x1 or 8x2, we refered to the pixel shaders ability to texture a pixel. Thus, when an application wanted to perform multitexturing, the hardware would perform about the same -- single pass graphics cut the performance of the 8x2 architecture in half because half the texturing poewr was ... this was much more important for early dx, fixed pipe, or opengl based games. DX9 through all that out the window, as it is now common to see many instructions and cycles spent on any given pixel.

    in a way, since there are only 16 texture units you might be able to say its something like 48x0.333 ... it really isn't possible to texture all 48 pixels every clock cycle ad infinitum. in an 8x2 architecture you really could texture each of 8 pixels with 2 textures every clock cycle forever.

    to put it more plainly, we are now doing much more actual work with the textures we load, so the focus has shifted from "texturing" a pixel to "shading" a pixel ... or fragment ... or whatever you wanna call it.

    it's entirely different then xenos as xenos uses a unified shader architecture.

    interestingly though, R580 supports a render to vertex buffer feature that allows you to turn your pixel shaders into vertex processors and spit the output straight back into the incoming vertex data.

    but i digress ....

    I'm wondering how a dual 7800GT/7800GTX stacked up against this card.

    i.e. Is the brand new system I bought literally 24 hours ago going to be able to compete?

    SLI figures is all over the review. Go read and look at the graphs again.
  • aschwabe - Tuesday, January 24, 2006 - link

    Ah, my bad, thanks.

    Go check out the review on hardocp.com. They have benchies for both the GTX 256 & GTX 512, SLI & non SLI.

    No my bad. I'm a bit slow. Only the GTX 512 SLI are in there. sorry!

    Just a few comments (some are being very picky I know)

    1) Why are you using the latest hardware with and old Seagate 7200.7 drive when the 7200.9 series is available? Also no FX-60?

    2) Disappointing to see no power consumption/noise levels in your testing...

    3) You are like the first site to show Crossfire XTX benchmarks? I am very confused... I thought there was only a XT Crossfire card so how do you get Crossfire XTX benchmarks?

    Otherwise good job :)

    crossfire xtx indicates that we ran a 1900 crossfire edition card in conjunction with a 1900 xtx .... this is as opposed to running the crossfire edition card in conjunction with a 1900 xt.

    crossfire does not synchronize GPU speed, so performance will be (slightly) better when pairing the faster card with the crossfire.

    fx-60 is slower than fx-57 for single threaded apps

    power consumption was supposed to be included, but we have had some power issues. We will be updating the article as soon as we can -- we didn't want to hold the entire piece in order to wait for power.

    harddrive performance is not going to affect anything but load times in our benchmarks.

    See my comment above. They are probably running an XTX card with the Crossfire Edition master card.

    Are gamers going insane. $500+ for video card is not a good price. Maybe its jsut me but are bragging rights really worth thats kind of money. Even if you played a game thats needs it you should be pissed at the game company thats puts a blot mess thats needs a $500 card.
