Nvidia is reportedly readying the GTX 980MX and 970MX for faster laptops

  1. Nvidia is reportedly preparing to release two new higher-performance mobile discrete graphics chips – the GeForce GTX 980MX, and the GTX 970MX – which will succeed the existing GTX 980M and 970M respectively.

    The GTX 980MX is set to include more CUDA cores than the GTX 980M, jumping from 1664 to 1536, with an accompanying raise in texture units (up to 104 from 96). The GPU is expected to be clocked at 1,048 MHz, although the memory system will remain the same at 5,000 MHz GDDR5 on a 256-bit bus, providing 160 GB/s of bandwidth to either 4 or 8 GB of VRAM.

    As you might have guessed, the GTX 970MX is designed to fit between the GTX 970M and GTX 980M, with an increase in CUDA cores (1408 up from 1280), texture units (88 up from 80) and ROPs (56 up from 48) compared to the 970M. The GPU will allegedly be clocked at 941 MHz, with either 3 or 6 GB of 5,000 MHz GDDR5 on a 192-bit bus, providing 120 GB/s of bandwidth.

    GTX 980 GTX 980MX GTX 980M GTX 970MX GTX 970M
    CUDA Cores 2048 1664 1536 1408 1280
    Texture Units 128 104 96 88 80
    ROPs 64 56 48
    Clock Speed 1218 MHz 1048 MHz 1038 MHz 941 MHz 924 MHz
    Memory 8 GB 256-bit GDDR5 at 7008 MHz (224 GB/s) 8/4 GB 256-bit GDDR5 at 5000 MHz (160 GB/s) 3/6 GB 192-bit GDDR5 at 5000 MHz (120 GB/s)
    TDP 150W 125W 100W
    GPU 28nm Maxwell GM204

    Like the 970M and 980M, the new MX-series chips will use a Maxwell-based GM204 GPU. With Nvidia's Pascal architecture just around the corner, both of these new mobile GPUs will likely be the last from the Maxwell line, and the last high-performance parts built on a 28nm process.

    Nvidia hasn't officially announced the 970MX or the 980MX at this stage, but it shouldn't be too long before we get confirmation of these products and their specs.

    Can you add the 970 to your chart... you have the 980 but it would be more complete to see the comparison between that card as well...

    "jumping from 1664 to 1536" You appear have the numbers reversed there.

    Seriously late in the game to be coming out with new iterations of existing chips, anyone who can wait for Pascal should be waiting for Pascal at this point in time.

    I know someone who thinks the 970M is the same as the desktop 970, wish I could show him this right now, not only does his 970M not match my desktop 970, the 970MX still won't. Although the 980MX is really close now, still not the same however, you can surely overclock the desktop card further as well.

    This should come at absolutely no surprise since the desktop cards aren't limited to the MXM-B/3.0 specification nor the 105mm * 82mm footprint (and more restrictive available cooling options).

    I actually thought Nvidia did reasonably well shoehorning a full-fat GTX 980 into an MXM form factor at any reasonable TDP.

    Oh absolutely, if I had the money I'd buy a laptop with one of these in it without hesitations, it's just I have no need for a laptop right now or the budget. They still get toasty however, and require an AC outlet to make proper use of it.

    This turned out to be false didn't it?

    Kind of depends on what rumours you go by.
    Can't say that MX parts are particularly needed, but like most mobile refreshes and rebrands, they are driven by OEM's desires for "new" models rather than the vendor since the market is almost entirely 100% OEM/ODM driven.
