NVIDIA is releasing the GeForce GTX 1080 Ti, a $699 GPU with performance and specifications similar to that of the NVIDIA Titan X:

Unveiled last week at GDC and launching [March 10th] is the GeForce GTX 1080 Ti. Based on NVIDIA's GP102 GPU – aka Bigger Pascal – the job of GTX 1080 Ti is to serve as a mid-cycle refresh of the GeForce 10 series. Like the GTX 980 Ti and GTX 780 Ti before it, that means taking advantage of improved manufacturing yields and reduced costs to push out a bigger, more powerful GPU to drive this year's flagship video card. And, for NVIDIA and their well-executed dominance of the high-end video card market, it's a chance to run up the score even more. With the GTX 1080 Ti, NVIDIA is aiming for what they're calling their greatest performance jump yet for a modern Ti product – around 35% on average. This would translate into a sizable upgrade for GeForce GTX 980 Ti owners and others for whom GTX 1080 wasn't the card they were looking for.

[...] Going by the numbers then, the GTX 1080 Ti offers just over 11.3 TFLOPS of FP32 performance. This puts the expected shader/texture performance of the card 28% ahead of the current GTX 1080, while the ROP throughput advantage stands 26%, and memory bandwidth at a much greater 51.2%. Real-world performance will of course be influenced by a blend of these factors, with memory bandwidth being the real wildcard. Otherwise, relative to the NVIDIA Titan X, the two cards should end up quite close, trading blows now and then.

Speaking of the Titan, on an interesting side note, NVIDIA isn't going to be doing anything to hurt the compute performance of the GTX 1080 Ti to differentiate the card from the Titan, which has proven popular with GPU compute customers. Crucially, this means that the GTX 1080 Ti gets the same 4:1 INT8 performance ratio of the Titan, which is critical to the cards' high neural networking inference performance. As a result the GTX 1080 Ti actually has slightly greater compute performance (on paper) than the Titan. And NVIDIA has been surprisingly candid in admitting that unless compute customers need the last 1GB of VRAM offered by the Titan, they're likely going to buy the GTX 1080 Ti instead.

The card includes 11 GB of Micron's second-generation GDDR5X memory operating at 11 Gbps compared to 12 GB of GDDR5X at 10 Gbps for the Titan X.

    the FP64 is gimped on these devices (1/32).

    They do make the P100(?) which is 1/2, like all other major chips.

    There y'go, 1.41 Gflops. This card is perhaps 300Gflops (DP), so 2 orders of magnitude...;-)

    What is more impressive is the power (250W?). I imagine the major research on the Cray machines was keeping them cool!!!

    The thing is as a molecular modeller , I'm still waiting for the next revision... the threshold for having sufficient computational power to calculate entirely within the GPU is almost upon us!!!

    thanks for the reply! Yeah, I had figured we were well past a cray by now, but didn't realize by how much; nice!

    I don't suppose when the next generation card comes around with upgraded memory capacity, that you'll wish it had even more memory so that you could do a finer grained analysis? =)
