While our recent review of the Alienware M17x R3 proved you could have a gaming notebook that was still capable of halfway decent battery life, the hybrid solution found in that machine was more the exception than the rule. NVIDIA is refreshing their mobile high end, and while that's mostly newsworthy on its own, the big improvement is Optimus support for every part in the GeForce 500M series, from top to bottom. That includes the king of the hill, the (slightly) new GeForce GTX 580M.

The recent refresh of the GeForce GTX 460M into the 560M was a welcome one, bringing Optimus support and higher clocks to what's liable to be their crown prince of budget mobile gaming. The GTX 560M is beginning to materialize in the market, but we were still left with an odd hole in NVIDIA's lineup at the top. That hole has now been filled, and thankfully it's at least a little more than the usual speedbump that goes along with a new moniker these days. Now every part in the 500M series can switch over to Sandy Bridge's integrated graphics while running on the battery, offering the best of both worlds.

NVIDIA's new top dog is the GeForce GTX 580M. Every spec on the press sheets is listed as "up to," but that's really par for the course. While NVIDIA's reps declined to comment on what chips are being used for the GTX 580M, you'll find the specs are a dead giveaway. The 580M seems to be a mobile version of the GF104/114 (more likely GF114), with 384 CUDA cores, with a main clock of 620MHz (yielding 1240MHz on the shader cores). Riding shotgun is a 256-bit memory bus supporting up to 2GB of GDDR5 clocked at an effective 3GHz. Those of you keeping score at home will note that's an improvement of 45MHz on the core (and thus 90MHz on the shaders), with the memory speed remaining constant. All told I'd expect performance in the neighborhood of the desktop GeForce GTX 460 1GB version (or at least, the original NVIDIA spec): not too shabby, but still an incremental improvement on the shipping GTX 485M. The major selling point is, again, Optimus support in the 580M.

On the heels of the GTX 580M is the GeForce GTX 570M. The 470M was a bit of an oddity in that while the 480M and 485M were easy enough to find, the 470M was largely a rarity. While the 580M sees the minor speedbump we've come to expect, the 570M is a major improvement over its seldom-used predecessor. The 570M likely uses the same silicon as the 580M (which is, again, more than likely a GF114), but while the 470M only had 288 CUDA cores, the 570M gets a healthy upgrade to 336. The 470M's 535MHz core clock also sees a boost to 575MHz, with the shaders clocked at 1150MHz. The 570M still retains the 470M's 192-bit memory bus, and will be configured with either 1.5GB or 3GB of GDDR5 clocked at an effective 3GHz, a marked improvement on the 470M's 2.5GHz memory clocks. All told performance should be somewhere between the desktop GeForce GTX 460 768MB and the GTX 460 SE. For mobile gaming, that's still not bad at all, and again it benefits from Optimus support.

NVIDIA also was able to point out specific models of notebooks that will be shipping with these parts. Availability in 17" Clevo notebooks should surprise no one, with the P270WN in particular supporting both 3D Vision and SLI'd GeForce GTX 580M's. Alienware's new M18x (which we have en route for review) will also be supporting the GeForce GTX 580M in SLI. And finally, the MSI GT780R shown above will be shipping with the GeForce GTX 570M.

NVIDIA expects notebooks featuring the new GPUs to be available for order from OEMs today.

    Nice to know,
    Thanks for posting!
    and Maybe you can open an online store. I suggest that you can wholesale fromhttp://www---- bestniceshoes ----com they have many brands of product, Including shoes, clothing, belts, bags and so on. but the price all is cheap .and they can directly send the order to your customer .However, data shows shipments are your company's.

    These will be a small boost over the 485m with the main difference being overclock headroom. I am interested to see how they are priced. So far on the Alienware M17x R3 it is $350 for a GTX 580m over a 6970m which is a hard sell.....

    Hope these do not make me too unhappy with my 6970m CF M18x :D

    And stoked for an Anandtech review of the M18x!

    Personally I'm waiting for an M14x review.

    Also, at this point in time we really need to stop and look if the overclocking is actually going to make any difference in frame rates vs. the battery it eats. I mean, if you're already running well over 60, I see no reason to overclock.

    It's coming VERY soon. I just finished testing the M14x. ;) Reply

    Optimus may help these power hungry beasts turn into all day productivity machines as long as you don't enable the dedicated graphics. Huge battery + integrated graphics = long life. I look forward to the reviews with one of these machines. Reply

    I don't think 620Mhz - 575Mhz = 75Mhz :-)
    Stupid spam comment detection need to add some more useless text just for the sake of it...

    ..when will we see optimus technology on the desktop? (i guess it's called synergy or something?) Reply

    Strange... Alienware is acting like the Nvidia GTX 580m is not compatible with the 120Hz screen. It won't let me configure that option.

    But the Nvidia press release says that the GTX 580m is compatible with 3D Vision.

    So which is it, compatible or not?

    I know of no reason why it wouldn't be compatible. Reply
