SLI Performance Reviewed at Anandtech

Posted by Zonk on from the two-chips-means-twice-the-shiny dept.

DarkSarin writes "Anandtech has a review of dual gpu's using nvidia's nforce4 SLI chipset. They are showing ~66 fps on doom3 at 1600x1200 with 4xAA turned on (a 75% increase in performance over a single gpu). It's not available yet, but it should be fairly soon."

    It requires a 350 watt when used with a standard system. So it shouldn't require 700, but still probably considerably more than 350.

  2. Math doesn't add up by chrismcdirty · · Score: 2, Informative

    So I'm expected to shell out 2x$$$ for a video card, extra $$$ for the mobo with 2xPCI-E, extra $$$ for the huge powersupply, but only get a 75% performace gain?

      The point made at the end of the article is that even if you can't afford two now, you can get one, and in 6 or 12 months not only will the current top of the line be cheaper, but you can get a huge performance increase by just buying an extra one (and maybe a bigger power supply) instead of replacing your current card entirely.

  3. Doom3 is capped at 60fps by fok · · Score: 3, Informative

    So 66fps is good enough ;)

  4. nVidia, best drivers bar none by Lisandro · · Score: 2, Informative

    It surprised me how painless the SLI setup process was described. Writting GPU drivers is complex enough without having to handle multiple accelerators, never mind having optimal performance AND making the install painless.

    nVidia does their homework with their drivers, and it shows. GPU drivers are 50% of their perfomance. It sucks for ATI, because they have the better hardware, but their drivers suck (and pretty much always did).
