Titan X - 3072 * 1215000000 = 3732480000000
Tesla P100 - 3584 * 1480000000 = 5304320000000
5304320000000 / 3732480000000 * 100 =~ 142.11
So 42% faster, stock vs. stock. Pretty much splits the difference between your 75% estimate and my 16% estimate. BUT...
The calculation is not correct since the Titan X on paper has a boost clock of 1075 (your 1215 is already an overclocked product).
Titan X - 3072 * 1075000000 = 3302400000000
Tesla P100 - 3584 * 1480000000 = 5304320000000
5304320000000 / 3302400000000 * 100 =~ 160.62
So 60% faster. Without considering any other optimization (FP16, new instructions, more instruction per cycle etc.)
My 75% was the estimation for all available shaders + even higher boost rate.
Titan X - 3072 * 1075000000 = 3302400000000
Titan P100 - 3840 * 1505000000 = 5779200000000
5779200000000 / 3302400000000 * 100 =~ 175.00
There you go, 75% on a possible new Titan P100.
About the Titan X doing 1515MHz: In the tests I read they never could bring the Titan X over 1300MHz (boost) without crashing or hitting the powerlimit. So how do you know your Titan X is really clocking 1515Mhz? Cause if that's just a number shown somewhere you cannot make serious calculations based on that.
No offence here, I'm just in pedantic mode.
The 300W limit is a problem indeed for the Tyan.
But let's see what comes up. It's obviously a big step forward.
