Nvidia announces notebook-bound GeForce GTX 480M

Remember that mysterious GeForce GTX 480M we encountered in a Eurocom laptop configuration page three weeks ago? Nvidia has now made things official. As Engadget reports, the GeForce GTX 480M—Nvidia’s very first mobile DirectX 11 product—will be out in the middle of June.

The 480M will feature 352 stream processors, a 425MHz core clock speed, an 850MHz shader speed, and up to 2GB of 1,200MHz GDDR5 RAM pushing data through a 256-bit memory interface. Nvidia’s product page for the mobile GPU quotes 897 gigaFLOPS of floating-point number-crunching power, a 42 Gtexels/s fill rate, and 76.8 GB/s of memory bandwidth. That’s down from 1.35 teraFLOPS, 42 Gtexels/s, and 177.4GB/s for the desktop GeForce GTX 480.

Nvidia tells us the GTX 480M is based on the same GF100 silicon as the desktop GeForce GTX 480, but “customized to fit into the notebook thermal budget.” That must be some serious customization. The desktop GeForce GTX 480 has a formidable 250W power envelope, and the already trimmed-down GTX 470 has a 215W rating. According to that Eurocom listing, however, the GTX 480M only draws up to 100W.

    If you think this is bad there is a notebook with 2 480s not 480m but regular 480s in sli…. 24 gb ram 4 tb hhd blah blah blah..

    But what made me laugh… its wall adapter is only rated at 300w…….

    Desperate times call for desperate measures, eh?

    Heck if they gave it the old 5900 cooler they could sell the notebooks as combo hairdryers and leafblowers.

    OW! HOT!

      that’s… what she said?

    This is a DTR-only chip.

    There is no way a laptop or smaller chassis has the volume to handle ~100W heat dissipation. Nevermind, that the batteries would give out under a hour.

    The M in 480M means manly, you go Nvidia! You pansies cant handle a real laptop gpu, get with the program.

    NUTS!!!!!!!!!!

      Agree on all points.

      My math puts it ~10-15% faster than Mobility 5870 for most intents and purposes. Essentially, it’s almost exactly what GTX480 is to 5870.

      BTW: Whoever wrote the product page needs a refresher course on their own products. Unless GF100 has the missing MUL, which it DOESN’T, this product will have 598.4 gigaflops, not 897.

      Their math uses the old (G80-G200) architecture’s flop count, which was 2+1 flops per shader, 2xMADD plus MUL (which mostly only did special function/interpolation, not shading). GF100 is strictly 2 flops per shader.

      I LOL at this product, and I LOL at their inability to know their own architecture.

    I have to hand it to Nvidia, this is a really ballsy move that I didn’t expect, since I assumed that they’d use their slimmed down GF104 cores rather than make a mobile version of the GTX 465.

    Either the company is really, really looking for gold for this one or they’re really, really desperate. More likely, it’s probably a mix of both, particularly the latter. I just pity the poor souls that would have to handle the warranties for the laptops these monsters will go into.

    I don’t think we want anyone who would buy this to be reproducing, anyway.

      The heat that a laptop with this GPU will put out will surely sterilize anyone who puts it on his/her lap, so no need to worry about that.

        I’m so glad you explained his joke. I wouldn’t have ever imagined that was what he was driving at if you hadn’t.

    • Mikael33

    Uh you mean 76.8GB/s of memory bandwidth, the 18.7 is the texture fill-rate

    • codedivine

    Now, if I am calculating right Nvidia is claiming this part can do 3 FLOPs/cycle/”CUDA core” whereas for the desktop parts like GTX 480, the calculations for peak Gflops was done assuming 1 MAD per cycle or 2 FLOPs/cycle/CUDA-core.

    Did something change? Is nvidia bringing back their dual-issue stuff? Or did they just change the way they count flops?

    GeForce 7950 GX2 use to draw 110Watts…

      • OneArmedScissor

      That is what I find really aggravating about the “efficiency” game that everyone plays now.

      Great, so computers get more work done per watt under a full load. That’s nice…if your PC is part of a rendering farm.

      Despite all the “improvements” the marketing may claim, the average desktop now is using more power overall than “inefficient” computers from 5 years ago did. It applies to everything. Even LED backlit monitors tend to use more power than older ones.

      And yet, on the laptop side of things, several $300-400 varieties, with the same sorts of CPUs and chipsets, can idle under 10w with the screen on. MOAR KOOL-AID PLZ!

    Isn’t the 5870 mobile unit only 50W?

      • Game_boy
      • 9 years ago

      Yes. But that’s really a 57xx part.

      Then again, this part [480M] should perform like a 5770 anyway. (352/480)*(850/1400) = 0.45 of a GTX 480 which should be about half a 5870 and therefore like a 5770.

      And therefore with the same 100W power envelope on the AMD side you can get dual 57xx parts.

        • khands
        • 9 years ago

        Yeah, I wasn’t saying it wasn’t less than the 5870, but it seems a little ridiculous that it’s half the TDP.

    Holy cow, zombie GPUs have come to take our precious laptops.

    100W! That’s just silly.

    They’re really struggling to find a use for those GF100s that failed binning. Mobile uses! Trim the dead shaders, and cut the clocks! Win!

      It’s Darwin-award worthy.

      Instead of killing those unworthy of reproducing, they’re now targeting our precious bodily fluids.
