While we've already shown you the specifications of a number of the upcoming 700-series graphics cards for desktops, we've shown you little about the mobile lineup. Hereby, we bring you the specifications of the GTX 780M, courtesy of VideoCardz.

Like the GTX 680M, the GTX 780M is based on the Kepler architecture. It features eight of the SMX units enabled, as compared to the seven that were enabled on the GTX 680M. Consequently, the card has 1536 CUDA cores running. This is the same number found on the desktop version of the GTX 680. Of course, though, the clock speeds are notably lower on the GTX 780M due to restrictions in heat production and power consumption for laptops and mobile devices. The core clock speed is at 771 MHz with a Boost speed of 797 MHz, featuring the newer Boost 2.0 technology.

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.

The folks at VideoCardz have also gotten some screenshots of the benchmarks; the average increase in performance (as compared to the GTX 680M) for the GTX 780M is a respectable 31 percent.Image Source: VideoCardzImage Source: VideoCardz

    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.

    Godamn. My graphic cards depreciates the fastest in all of my possessions.

    Put one of those in next gen tablet PCs (a la Microsoft Surface Pro) with good battery management and I am intrigued.
