AFAIK, not. Or if it does, they are disabled. (AFAIK, only GP100 has DPFPs)

They disabled it on the more recent Titans. I believe the Titan Z is the last Titan card to have it.

Those are GPU dependent and AFAIK, all the cards that use GP106/GP104/GP102 don't have any...

Only GP100, which is used in the Quadro P100 and Teslas

NVIDIA's consumer GPUs have 1/32 FP32 FP64 performance. If that confuses you, basically take the FP32 (single precision) performance and divide it by 32, that's its FP64 (double precision) performance.

 

Titans historically were 1/8 FP32, but for some reason Titan XP no longer has this. Nor do a lot of the Quadro cards.

I have a blog! And a list of guides I've posted

There are a couple of GK chips that have it. The original Titan, Titan Black and Titan Z all have it. Titan Black uses the GK110 chip.

Yes it does

181 GFLOPS 

That's simply a measure of performance, not actually having the technology to boost double precision performance. 

 

http://arrayfire.com/explaining-fp64-performance-on-gpus/

 

Cards like the Titan Black allow the card to be switched to TCC mode and selecting between 13 and 124 FP32. It compromises single precision performance in exchange for boosting double precision performance. It allows the Titan Black to match a K40C in terms of double precision performance, a $3,000+ card
