If you have experience overclocking the TXP then you would know that it is very easy to overclock the VRAM past the point where it improves frame rates and performance. The improved memory speeds compared to the TXP melt away the more you overclock.
The advantage of the 1080Ti which is a direct quote from pcgamesn.com
"he new 7-phase dual-FET design spreads the power load more than the Titan X and allows for less power leakage (realised in GPU terms as heat) and a cleaner supply of juice. This is partly how Nvidia have been able to ship the standard GTX 1080 Ti cards with a higher out-of-the-box boost clock than the Titan X."
So Nvidia essentially improved the cards power distribution and improved memory speeds in order to match the TXP's performance while at the same time cutting ROPS, 96 to 88, and cutting the l2 cache 3072 to 2816.
the thermal threshold of the chip has actually been lowered from its Titan X days. The Titan X will only start throttling its chip when the silicon tops 94°C, while the GTX 1080 Ti will start reining in its GPU at 91°C. So for those people who like to push their cards to the limit means less ability to overclock.
So back to your question. Why is the TXP superior? If your under water and pushing very high resolutions 5K or greater the TXP is better equipped.
Now for people who do not overclock, water cool, or already own a TXP, the answer is simple.
Agree with a fair bit of your post, but not other parts. Definitely agree if you have a TXP, would keep it, unless you can sell them for a steller price. Also all the hype and marketing show it as killing the TXP, when really load of crap and for most the part at stock they are similar or slightly in favour of 1080Ti due to higher clocks as you pointed out.
The 1080Ti, can make up the memory overclock gain once again and hit 12 Ghz or so to make up the delta when you OC the Titan XP Memory so increase that delta again. 91 vs 94 degrees will not be making a difference as you will be throttling pretty hard on both cards far before then. That limit is the maximum GPU temp limits and you will not be able to get that high, boost drops far before then on both. Also if your hitting those temps, you would be on air which would then ask the question, why would you not get a 1080Ti AIB which will be able to sustain higher clocks and once again outperform the TXP for cheaper.
Likewise even these days if you are into overclocking and watercooling etc, then then 1080Ti mostly makes more sense. It may not be able to absolutely match the TXP on the top end. But for a % or so for less performance (depending on the chip) for nearly half the price, that's considerable IMO and more then makes up for that for 99% of people. Last 1% or so of course want the best at any price and no doubt that 1% is considerable on this site, it is indeed OCN and has overclock in the name
