How Much RAM Does Your Graphics Card Really Need?

Game Benchmark: World In Conflict

With World in Conflict, we'll try the same strategy we used with Far Cry 2: we'll run once with the highest settings available, and then once again with 4xAA and 16x anisotropic filtering (AF) in order to increase texture memory usage.

Now for the first run results:

There appear to be no significant differences of which to speak. Now, let's add 4xAA and 16xAF:

It's a very close race. The 512MB card does seem to suffer a minor performance penalty at 2560x1900, but at 1920x1200 there's nothing significant to talk about. World in Conflict is likely more CPU-bound than anything.

    Great article guys. I've debated this many times with friends- good to see a definite result. Heh, GTX 275 w/ 896 works well @ 1680x1050 for me. I doubt I'd need anything higher than that for my resolution.

    I really like the alternating images you use in these articles, they are very helpful and make it much easier to compare the various detail settings.

    Also, great article overall. Keep up the good work!

    Thanks burnley, animated GIFs are a bit of a pain to make, but it's nice to know they're appreciated. :)

    This was very interesting. But I would like to see the performance difference from a mid-stream (say a 4850) as compared to a high end video card. Would it have made sense to spring for the 1GB 4850, or would there be no difference because of the cards inherent limitations? And the same thing with the lower level cards. At what point in the hierarchy of video cards does springing for more than the reference memory levels make sense?

    With lower end cards you'd see the same effect, but with the lower frame-rates that those cards would produce. The end result is the same: one they run out of RAM at a certain setting, the performance will suffer, but until then it's the same across the board.

    How much ram will the 5870 eyefinity version need?

    Depends on the resolution and settings just like everything else. but it's a good question, if there's enough interest in this article I'll look into that in the future.

    Im surprised that Crysis doesnt utilize all the RAM(even for an older title) for distance similarly to titles like GTA. Im sure the new Crytek engine will make use of Ram so we can see even buildings and huge alien robots further in the distance with vivid details.

    We can only look forward to a more intense and visually stunning Crysis 2 as I can only imagine how the story would progress and end up being in space. I can imagine huge asteroids looking as real coming at the player using nvidias 3d vision and utilizing AA in order to make it apparent from a distance.

    Think Halo style world but with unrivaled graphics and a more realistic feel with DX11.

  • How about doing this same comparison with crossfire setups?
