AMD Radeon HD 6990 4 GB Review: Antilles Makes (Too Much) Noise

Features

Several months late and supposedly only a couple of weeks ahead of Nvidia's own dual-GPU flagship launch, AMD's Radeon HD 6990 has no trouble establishing performance superiority. But does speed at any cost sacrifice too much of the user experience?

Benchmark Results: Metro 2033 (DX11)

At 1680x1050 and 1920x1080, the Radeon HD 6990 and Radeon HD 5970 take first and second place, respectively.

But 2560x1600 or higher is where you’d expect to use a dual-GPU card after all, and the 5970 stumbles a bit at that resolution with AAA turned on. Once we swap over to 4x MSAA, each Cypress GPU’s 1 GB frame buffer is overwhelmed and we see performance crater.

Fortunately for AMD, the Radeon HD 5970 is ancient history—you can’t even really buy the thing anymore. Today is all about the 6990, and the 6990 dominates. Even at 2560x1600, the GeForce GTX 580 trails by a fair margin (even more so if you take multi-sample anti-aliasing into account). There’s really no question as to which card is on top.

    Killer Card!

    Out of spec for default seems kind of weird though.

    Great job AMD. You need to expect noise and heat when dealing with a card that beasts out that kind of performance, it's part of the territory.

    This thing is a monster, 375W TDP, 4GB of VRAM! Some people don't even have 4GB of regular RAM in their systems, let alone on their video card.

    Did I miss the load power draw? I just noticed the idle and noise ratings. It would be informative to see the power draw of Crossfire 6990s and overclocked i7. I see the graph, but a chart with CPU only and GPU only followed by a combination of both would be nice to see.

    For the people that actually buy this card, i'm sure they'll be able to afford an aftermarket cooler for this thing once they come out...

    We don't have two cards here to test, unfortunately. The logged load results for a single card are on the same page, though!

    things we need to see are this thing water cooled.

    and tested at 7680 x 1600

    that will see just how well it does.

    That thing is an absolute monster of a card.

    They really should have made it 32nm. then the power draw would have fallen below 300w and the thing would be cooler.

    STILL NICE WORK AMD

    Pretty fast i wonder if this will be cheaper then 2 GTX 570's or 2 6950's?
    But omg this thing is freakin loud. What's the point of having a quite system now with Noctua fans :(

    Its hot, sucks alot of power, and costs a ton. But i still want one.








    Badly
