  1. "Beyond the GPU core, we also see that the GTX 780M will carry 4 GB of GDDR5 memory, which will run at an effective speed of 6.00 GHz, and run over a 256-bit memory interface. This lets the card pump out 160 GB/s."

    I think 256-bit GDDR5 at 6 GHz equals 192 GBps of bandwidth. In other words the same memory bandwidth as the GTX680.

    In any case the boost in memory bandwidth in itself should give mobile Kepler a healthy boost in performance. That really was the main thing holding back much of the 600m series.
  2. Godamn. My graphic cards depreciates the fastest in all of my possessions.
  3. Put one of those in next gen tablet PCs (a la Microsoft Surface Pro) with good battery management and I am intrigued.
  4. A card like this is already available and it is called 680mx.
    Just overclocked to 770mhz from original 720mhz of the 680mx.
    But look at the 680m benchmarks on skyrim: 1080p LOW DETAILS 55 fps???
    On a 486dx maybe.
    Sorry Tom, specs might be true but I don't believe these benchmarks ^_^

    Not quite. First the mx is only available in certain iMac's. It has a 5 GHz memory clock as opposed to the rumored 6 GHz clock on the 780m. And don't underestimate the effectiveness of GPU boost 2.0, it's much better at sustaining boost clocks than the original. And this isn't mentioned anywhere in the article, but I wouldn't be surprised if the 780m uses the upcoming gk104 revision that will probably show up first in the GTX770. From what I've heard it should provide slightly improved power efficiency and thermals over current silicon.

    I don't think that's a reasonable expectation for a dGPU targeted at high-end gaming laptops.

    The GTX 780m is NEVER going in a tablet. This thing is going to, in all likelihood have a TDP north of 100 watts, since that's what the 680M is rated at and this thing has more on die resources. Not only does that mean that the tablet would have to dissipate that much heat, but the GPU alone could drain the battery of the surface Pro (42 watt hours) in well under 30 minutes, not to mention the impact of the rest of the system.
  8. I believe the original GTX 680M was Fermi-based. The 680MX, on the other hand,was Kepler based.
  9. Nope, 675m is an overclocked 580m (fermi based) while 675mx and 680m are kepler based :-)
  10. Turns out that gtx 770 is a bios flashed 680. (check reddit)
    The 780 looks to be a castrated gtx titan.
  11. 771 to 797 is not really a boost; at least not a noticeable one. why not boost to 850MHz or higher?
  12. From what I read in this article, the X780M is just the superclocked desktop version of the X680... Not as impressive as I was expecting
  13. Holy crap, this may be the first time in history the mobile part matches the desktop part in everything but clock speed. These 780m's are looking great. I hope they will be a compatible gpu upgrade for my m18x r1

  15. Does anyone know the release date of the GTX780M? There are already some listings on eBay for the upgrade kits for Alienware but it has not been listen on the nVidia website yet.
