For comparison, the 1080Ti is ~11.3TFLOPS + 11GB RAM @ $700 vs the Titan at ~12.1TFLOPS + 12GB RAM @ $1200. ~9% more performance for 70% more money. https://en

they don't call it the bleeding edge for nothing.

Yeah, I kinda hoped the next Titan will have decent FP16 performance...

I have been evaluating buying a 1080Ti recently; it appears to also have the highest cores per $. Is the 1080Ti really then the most efficient card for general purpose HPC work on Linux (numerics)? The 1080 is a step down but also competitively priced. Curious about your thoughts, as I couldn't find a guide on this stuff on the web. edit: The Tesla K20 is also in competition in my view (despite the much higher cost) due to its focus on higher double-precision performance.

  As far as performance per $ goes I actually think the gtx 1070 is the sweet spot currently.
  - tanderson92 10y ago
    If you're measuring cores per $ or GFLOP (single precision or double precision) per $ the ordering (decreasing) is the same: 1080 ti, 1080, 1070. Tesla wins on GFLOP (double precision) per $. At least according to current lowest newegg prices. It is all quite close though.

  We do a lot of work on video encoding. We have had a K80, Titan X(Maxwell), Titan X(Pascal), 1080, 1080Ti, and others (including render-farms based on GTX980's). General thoughts: Don't expect to get _any_ information out of NVidia unless you are running everything on their hardware compatibility lists (i.e. server-case) Do not mix & match consumer-rated gear with 'professional' gear. (i.e. If you put the K80 in a system with a GTX1080, then the Nvidia drivers restrict the number of available processing cores to 2 per device) Air-flow: The Tesla's run HOT even with a blower attached, and/or installed in the recommended case. NVENC: the Pascal-based cards performance is incredibly faster AND better then the Kepler-based cards. For anybody else doing Video encoding work: Grab an Nvidia TK1/jetson dev-kit. This little card is a MONSTER and can handle everything we throw at it without breaking a sweat.

    For clarification - is that a Jetson TK1 or TX1?
    - Nexxxeh 10y ago
      Or TX2 which is Pascal-based and came out last month?
      - VA3FXP 10y ago
        I have seen that the TX2 was recently released. I let our R&D department know about it. (I don't know if they ordered it or not)

Not sure what exactly do you mean by "number of processing cores"? I use two development boxes on a regular basis with Teslas side-by-side with GeForce cards and they all work just fine.

On the other hand, video cards meant for games generally can't take sustained load. By that I mean you can't run them at 90-100% load for days on end in e.g. a render farm, they invariably melt. You're paying for better build quality and for having enough money for a render farm.

I may be totally wrong here, but from what I remember the Titan line handles up to double precision floats whereas the gtx line handles only single? Games don't really need the double precision so it's overkill for gtx. Can anyone confirm?
