NVIDIA Launches GeForce 700M Mobile GPUs With Improved Power Management 35

MojoKid writes "Every year, AMD and NVIDIA re-brand their GPU product lines, regardless of whether the underlying hardware has changed. This annual maneuver is a sop to OEMs, who like yearly refreshes and higher numbers. The big introduction NVIDIA is making this year is what it calls GPU Boost 2.0. When NVIDIA launched the GTX Titan in February, it discussed a new iteration of GPU Boost technology that measured GPU temperature rather than estimating TDP. This new approach gave NVIDIA finer-grained control over clock speeds and thermal thresholds, thereby allowing for better dynamic overclocking. That technology is coming to the GeForce 700M mobile family. In notebooks, GPU Boost 2.0 is a combination of thermal and application monitoring. GPU Boost 2.0 is designed to reflect an important fact of 3D gaming — no two applications use the same amount of power. The variance can be significant, even within the same game. It's therefore possible for the GPU to adjust clocks dynamically in order to maximize frame rates. Put the two together, and NVIDIA believes it can substantially improve FPS speeds without compromising thermals or electrical safe operating margins."

    now it's rot26. When is this bullshit going to end?

    the only useful point from TFA:
    The Bottom Line:
    The GT 730M and 735M aren't rebadged GT 600M parts, but they may actually be slower than the cards they are replacing. The GT 740M and 750M are rebadged GT 640/650 cards with higher core clocks and GPU Boost, but less memory bandwidth as well.

    So some worth buying, but not if you want something faster or with better memory access bandwidth.

      I've done enough testing of "new" power saving for mobile parts from Nvidia.. I had enough fun the three times the GeForce 8600M killed my laptop's motherboard. (With corresponding warranty replacement.).

      A lot of laptops come with an nvidia and an Intel GPU. The Intel being used for desktop rendering to save juice. It would be cooler if nvidia worked in the direction of making laptops that utilize them to not need a competing companies chip to be efficient.

        Well current Intel video hardware is part of the CPU itself nowadays (at least for Core i3/i5/i7 parts, lower end parts I'd have to double check). There's nothing Nivida can do that would make running two chips (their GPU and Intel's CPU/GPU combo chip) more power efficient than only running only one of those two when only one's needed.

        they don't need competing companies chip to be efficient.. but sometimes you get the competing chip wanted you it or not.

        of course the solution "should" be that the built in chip would be effective enough. but intel promises every year that in two years you will not need nvidia - and they have been promising that for about a decade now.

    • Meh AMD has been doing the same thing, use the 48xx or 58xx if you want crazy framerates while being able to cook supper on the chips, the 6xx and 7xxx don't get the high framerates but also don't have the high heat.

      I figure the "ZOMFG its all gotta be mobile like teh iPhone yo!" bubble will pop like every other bubble and things will go back to normal but until then I have a feeling both AMD and Nvidia are gonna be so busy playing low power limbo to see how long they can go that pretty much everything bu

      • I wonder if the low power multi-dsp-line chips would be more useful for GPU-processing of data as streams, even if they might not be so great for frame-rates and gaming. Perhaps they're good for flops/watt usage ratio or something? Or is that restricted to such a small subset of users (CFD = computational fluid dynamics?) that it's not useful at all?
        • I'm sorry but you lost me, are you talking about the chips in TFA or some other chips? Because i have never heard a GPU referred to as a "multi-dsp-line chip" so you might as well have said "I wonder if the fleegal will be a good flimjam" for all the sense that sentence made.

          Now if you are asking if some funky job you have can be done on a GP-GPU like the newer Nvidia and AMD chips? While I'm no expert in the new chips, especially the new Nvidia designs, preferring AMD, from the look of what I have seen it

    • Maybe you want something that uses less power. Speed is not the only factor.

    But the question is: can it mine bitcoins better than AMDs? :) ... sorry, i was missing the daily bitcoin article today ...

    • way ahead of you (weeks sadly) and no it cannot. Doesn't matter though, as a Radeon 5830 @ 240W can get about 315MH/s and the new ASICs can go 2W, 4,500MH/s. That's almost 2000x more efficient or something.

    A million stupid ass Hollywood movies have finally been vindicated. At long last, a software hack will be able to set the laptop on fire.

  • How old is this story? There are already benchmarks out as of like 4 weeks ago. I even have favorited a laptop with a 730M for sale as of 3 weeks ago. The 730M is supposed to absolutely crush everything before it, even the 540M. It's so much better at video playback, it's not even funny. I know this because my company needed a laptop to play 20MBps videos and our A8 Llano laptop and NVS140 laptop weren't even close.
  • I like Windows better when it's in a virtual environment, but the software that makes me want Windows at all is graphics processor intensive.
