Nvidia Pascal Titan X will not feature faster FP64 or FP16 performance
The original GTX Titan GPU had a unique characteristic that made it popular for more than just gaming, it had support for Double Precision, FP64, compute, allowing people to access some huge amounts of compute performance at a price that is much lower than Nvidia's Tesla or Quadro GPUs.
With the release of the Maxwell Titan X that changed, with the Titan X having the same Double precision compute scaling/ rates as their GTX Gaming counterparts, taking away the attractive budget compute properties of the Original GTX Titan.
Now Nvidia has confirmed that the Pascal GTX Titan X will not feature increased FP64 and FP16 rates over GP104, making the Titan X an Ultra-powerful Gaming GPU and nothing more. While the Pascal GTX Titan X will offer best in class gaming performance when it launches, it will still come in at an eye-watering price of $1200 and leave the budget FP64 compute crowd without the "old style" Titan of their dreams.
Below are the specification of Nvidia's Pascal Titan X compared to their GTX 1080 and other Pascal powered GPUs. The GTX Titan X will come with 12 GB of GDDR5X VRAM and over 1000 more CUDA cores than the GTX 1080, though they will come with lower clock speeds.

It seems that Nvidia has decided to build separate compute and gaming GPUs this generation, building GP100 for high-performance computing with NVLink support and several other compute-focused features while GP102 focuses solely on gaming performance.
