Apart from the Tesla M40 being announced 8 months after the Titan X? Or the Titan X being marketed mainly towards prosumer use (e.g. renderfarms, non-mission-critical compute) and the actual gamer card (the 980Ti) being released a few months after with more SMs enabled? The top-end compute and top-end gaming (x80Ti) cards have all shared the same Gxx00 die for the last several generations. That is unlikely to change. Dies will be binned by available (non-defect) SMXs, and possible sub-SMX binning for the FP64 modules (the GTX 970 demonstrated very fine binning capability) and other 'enterprise' features that are unused for consumer cards (like ECC). Nvidia have said P100 OEM servers will ship Q1 2017, so I can't imaging a prosumer or consumer version arriving more than 1/2 months sooner than that, if not later.
