The 990FX Chipset Arrives: AMD And SLI Rise Again

By Chris Angelini
published

AMD is laying the foundation for its Socket AM3+, Bulldozer-based Zambezi processors with the 990FX chipset, functionally identical to 890FX. The big news is that motherboard vendors are licensing SLI again, and we want to compare performance to Intel.

Benchmark Results: Just Cause 2 (DX11)

The same thing (almost) happens in Just Cause 2. AMD’s Phenom II gets stuck right around 45 frames per second, regardless of resolution. And although we apply anti-aliasing and anisotropic filtering, neither feature has much of an effect on performance, indicating that our two GeForce GTX 570s still have more to give here. Something else is artificially limiting these results.

Intel’s platform hits a ceiling at a higher frame rate—typically around 60 frames per second. It’s only really at 2560x1600 with AA and AF cranked that performance takes a more significant ding.

    Tom's, what the hell is this? "At the end of the day, it's the graphics cards which are the bottleneck."
    Did you go about benchmarking graphics cards, or was this a motherboard/cpu comparison? I'm tired of hearing this excuse all the time. We know you have a pair of 6990s and 590s in your shop. Get rid of that stupid bottleneck and DO IT RIGHT!

    I'd keep in mind that this performance review was made it with an AM3 CPU and not with the new generation.

    What performance review? They didn't get to test anything. LOL

    Thanks for the review, but at lower resolutions we all know that the CPU differences will become clear. So you just proved that if a game is taxing on the GPUs, both solutions are equal and when the graphics card ain't being taxed, CPU differences become apparent... Ok, thanks for proving what we already know once more (not being sarcastic here >_

    Uhm... that last comment of mine was cut in half with the missing char of that face... I guess that's an escape char; oh well.

    What is missing said something like:

    ...here "face"), but you said you wanted to test AMD's SLI on their 990FX vs Intel's SLI. So, IMO, you need less graphics horse power: like 2 GTS250's or 2 GTX460's or 2 GTX560's (not ti's) to tax the graphics subsystem and really show the differences. Maybe up the resolution also to really show if there is a difference between AMD's or Intel's SLI.

    Thanks again for the Article, Mr Chris.

    Cheers!
