No point comparing the cuda performance. Tensor cores have 110Tflops performance. Thats like 5 Vega's

Not an expert on algorithms but the AI workloads seem to be pretty different from crypto. First we would need a completely new mining sowtware anyway to use the tensor cores...
Again, the Tensor cores are HALF PRECISION FLOATING POINT - not comparable to much of everything else.
They also are probably useless for mining, as mining wants INTEGER operations and "matrix" stuff isn't going to help in a mining situation.
