The reason why anyone would care - We've put a lot of work in performance for memory bound kernels, predictable latency and lowest latency.  (We don't generate any PTX and go direct to bare metal codegen tied with our own very small runtime.  We officially only support Tesla 2050/2070 cards at this time, but ping me if you have another card you can test with)
