Indeed, it was the reverse until recently but P100 is compute
capability 6.0, the latest GTX cards are 6.1 but V100 is already 7.
Performance-wise P100 is reasonably close to commodity cards on the
Tensorflow benchmarks (especially on 1 or 2 cards).
I don't have figures at hand but currently V100 is not too far from
them either as far as Deep Learning tasks are concerned.
This may change when TF moves to CUDA 9 and cuDNN 7 in the next release.

>>Anyhow, I spoke to an NVIDIA rep about it at SC17 and he kind of said “we are happy you’re buying whatever chip of ours). I said, sure, maybe, but I understand you’re putting the screws to the systems vendors so how are we supposed to buy them. Didn’t get a real concrete answer.
