GeForce GTX 580M SLI Vs. Radeon HD 6990M CrossFire

A flagship graphics launch is bound to fail unless it's the fastest game in town. Well, both AMD and Nvidia say their respective juggernauts have that title. Clearly, only one company can be right. Is the Radeon HD 6990M or GeForce GTX 580M quicker?

Power Consumption And Battery Life

With different CPUs and hard drives in the old and new systems, we can only say that the Radeon HD 6990M appears to draw more power than the Radeon HD 6970M at full load. The evidence is a little more convincing when we say Nvidia's GeForce GTX 580M draws more full-load power than its GTX 485M predecessor.

It's easier to compare systems that employ the same CPU and drives.

The Radeon HD 6990M draws around 14% less power than the GeForce 580M in 3D mode, while the GeForce GTX 580M has lower power consumption in 2D mode. SLI and CrossFire change the picture slightly at idle, though Nvidia's GeForce combination is still super-thirsty at full load.

Battery Eater Pro applies a minimal 3D load that appears  minor enough to keep Nvidia's cards from running at full blast, adding several minutes to overall battery life. While desktop replacement notebooks are not intended to run off-the-wall for extended periods, it’s nice to know that you’ll be able to check your email while taking a coffee break.

    Good to see that the performance of the SLI 580m lives up to the name.

    I'm amazed that this product even exists. The market for people willing to pay $7k for a behemoth gaming laptop has to be pretty miniscule.

    Come on, AMD, I've seen too many articles like this declaring Nvidia's new solution to be the superior one. We know that AMD's cards tend to be more power-efficient, but that only goes so far for some people. Keep that advantage certainly, but become more competitive with overall performance as well.

    Do you really need this much performance in a laptop, I curious. A GTX 560M could run most games on medium-high anyways (on a laptop) those laptops run about $1100, the saved money could get you a beast SB-E or BD comp and then some left for the college fund.

Because 1920x1080 seems to be a fairly popular resolution for 17" notebooks, and a single GTX 580M appears barely-adequate for medium-settings at that resolution. Well, maybe a single HD 6990M would do. That's why the article suggested the HD 6990M might be a top solution for slightly smaller notebooks, aka "normal sized" 17" notebooks.

    iam2thecrowe377W lol, that needs a big ass AC Adaptor!Remember that's input wattage FOR the adapter. The output was STILL less than 300W. These high-capacity power bricks are far from being 80-Plus Gold rated!

    This entire article is eminently STUPID! Who is going to spend that kind of money on a notebook simply so they can play games on it?

    And is there a human being on this planet that can make use of a resolution like 1920x1080 on a 17" notebook screen in order to play games?

    It is little wonder that the rest of the world finds us degenerate when we will indulge ourselves with toys like this, and at such a scandalous price, while millions of our fellow human beings are simply starving to death as we speak ... ;(
