These cards are designed specifically for scientific computing. They have a cuda core that can do 4x4 matrix multiplication in 1 GPU cycle. The kind of optimization like Bitcoin mining ASICs.
So here's my question: how will GPU mining evolve? Currently any gaming card can mine reasonably well. But as Nvidia specializing their cards to deep learning and AMD specializing their cards to memory performance, it's become harder to democratize PoW mining. 4x4 matrix multiplication (or some future ISA innovations) could prove huge in some algos but a $15000 card is not something that common people will buy.
