Benchmarking software should do more to provide a clean and meaningful representation of the distribution of performance - people care more about a card's worst case than its best or average.
Another significant consideration - as alluded to in the TensorFlow comment - is the compute performance.
Although compute performance is not yet that important from a gaming perspective, I would be rather surprised not to see some games start to utilise it for engine functionality - especially after Vulcan and OpenCL merge.
Wait to see the performance of the card as a whole, and consider the implications for the next generation before you declare the card a non-starter and evolutionary dead-end.
