During the keynote at GTC, NVIDIA's CEO quoted the single precision compute performance as 7.0 TFLOPS, which differs from the table above. The 6.14 TFLOPS rating above is based on the base clock of the GPU while the 7.0 TFLOPS number is based on "peak" clock rate. Also, just for reference, at the rated Boost clock the Titan X is rated at 6.60 TFLOPS.
A unique characteristic of this TITAN X card is that it does not have an accelerated performance configuration for double precision computing, which is something that both the TITAN and the TITAN Black had before it. The double precision performance is still a 1/32nd ratio (relative to single precision). That gives the TITAN X DP compute capability at just 192 GFLOPS. For reference, the TITAN Black has DP performance rated at 1707 GFLOPS with a 1/3rd ratio of the GPU’s 5.12 TFLOPS single precision capability. It appears that NVIDIA is not simply disabling the double precision compute capability on the GM200 GPU, hiding it and saving it for another implementation. Based on the die size, shader count and transistor count, it looks GM200 just doesn't have it.
