ClojureCUDA – A Clojure library for GPU programming

Actually, I doubt that performance itself will be much different, since ClojureCL/OpenCL is quite good, even on Nvidia.

The main benefits of using ClojureCUDA over ClojureCL may be some CUDA-specific functionality, and access to CUDA libraries such as cuBLAS, cuFFT, and cuDNN from Clojure.
