Given that CUDAnative.jl is beating CUDA c in some benchmarks and in others it is a bit slower, I would suspect that NUMBA is similar in performance. The thing where the Julia CUDA support really shines is that it is supporting arbitrary Julia structs and not just a blessed few datatypes like Float32.
