Why are TI's chosen over Titans for Gaming? (Looking for specifics)

[farmfowls]

I've always wanted to know the specifics of this and thought it was time to ask with the new gen GPU's looming. It's been the case for a long time now that if you're wanting the best card for gaming, the Titan is always said to be unnecessary and the top tier TI is the way to go. My two questions are, why is this and is this true? Why is it that the Titan is overkill and considered a waste of money (for gaming) in comparison to the top tier Ti cards? I understand that the Titans are more directed towards enterprise use, A.I, rendering etc but what is the technical reason (specs or otherwise)? I vaguely remember (could be completely wrong) that the generations ago Titans had certain boosted specs (for rendering etc) but also had slightly lowered and seemingly more important specs (towards gaming). Between the Titan RTX and the 2080ti, the Titan has more CUDA cores for example and I'm not seeing something jump out at me as the reason. Is it that the Titan would perform better but the steep increase in price doesn't justify it? Can someone clue me in?

The early titans, up to the Titan Black, had double precision FP64 capabilities, which is entirely useless for gaming but beneficial for rendering, CAD and the likes. 

 

They got rid of this later on and made them a gaming only card (at least, marketed that way). The reason people don't recommend or use them is the price and that's about it. They offer a massive reduction in price to performance compared to the top end Ti cards and don't make sense from a productivity standpoint either. The only reason Nvidia still makes them is likely because people will buy them if they really don't care about the cost and want the best gaming card possible, rather than them really having any reasonable use case.

In Pascal era, the 1080Ti essentially performed the same as the comparable Titan (further confused was it that gen that had multiple Titans?). Although the Titan had more cores, the Ti's were generally clocked higher so you get essentially the same performance, unless you upgraded the cooling and overclocked the Titans too.

 

Think there was more of a difference in Turing generation but the price gap made it "not worth it" for most.
