back to article Nvidia tears wraps off GeForce Titan X (again) and $10,000 GPU brain for DIY self-driving cars

Nvidia CEO Jen-Hsun Huang confirmed the arrival of the GeForce Titan X just a few minutes ago today, dubbing it Nvi's fastest single-chip GPU to date. He also showed off two development kits: a $15,000 deep-learning system, and a $10,000 DIY self-driving car brain. The US chip maker's boss was speaking at this year's GPU …

    hmmm

    the increased memory is welcome if it is flat access.

    If this is maxwell, why so hot?

    Why is memory bandwidth not increased with cuda cores?

    I guess we'll have to wait for the linpack tests...

      It has 50% more shaders, 50% more silicon and a 50% wider memory bus than the GTX 980, with three times as much memory, so 50% more power despite a slightly lower core clock isn't terribly surprising.

    - suspect there will be some memory magic and you won't be able to use the full 12GB, based on the lesser Maxwell's you should get around 10.5GB full speed. Still lots...

    - heat is likely related to die size. It is a very big die (harder to cool when everything is busy) and hard to produce flawless dies (due to the number of dies from each wafer) so likely to suffer some leakage.

    - Memory bandwidth is bus width x speed - they haven't changed from the GTX Titan Black and based on size/heat, a larger bus would have been a step to far on 28nm process.

    - Linpack I can't guess at. Sufficient? :)

      Re: hmmm

      LINPACK is reported as double-precision, which is why Nvidia doesn't talk about it. At 0.2 TFlops it is pretty poor.

      I have a few Intel MICs and they all do 2xSP for 1DP so a much more balanced arch. YMMV of course.

      They could have made wider memory since there are fewer texture units (which I think carry very fast memory), a 512 bit bus would greatly help utility.

      Re: hmmm

      It has twice the memory of the Titan Black, as you say on the same bus width. I'd say it's all at full speed.

    most trannies on a chip ?

    is this the most transistors on a chip ever then ?

    8 billion. mental.

      But will it run Cry...oh yeah. I see it does.

        Single-GPU UHD gaming with everything turned to maximum and sensible frame rates. How far we've come...

    Huang rules....??

    "The future of your car will be digital displays, touch, and gesture."

    Huang must still be living by Vietnam rules (or wherever he is from), because the first 2 are against road rules in many U.S. states (maybe all?). As far as the gestures, well, turn your blinker off asshole!

    P.S. I know it's technically called a "Turn Signal"!

        For some reason when I read that, I imagined my car running down the road, then my car BSOD'ing. Of course the driver is out of date :-)

    Competition

    Has AMD / ATI got anything that compares to this ?

    The integrated AMD APU are awesome for general Win 8 ui compared to their Intel counterparts (price point) I'm just hoping they haven't dropped the ball with the high end stuff.

    Would be nice to see some numbers even if they are totally out of the game and going the way of Cyrix.

      Re: Competition

      Not yet, but the R9 390 looks like it's expected to at least match this when it's launched in the next few months, although whether it's 20nm or 28nm seems to be uncertain.

    Drive PX circuit board cost $10,000

    glad to see it's only a dev board. Would hate to see its price added to the cost of my future driverless car.
