Yes, on their site they post Torch CuDNN v4 as faster than Leaf [0]. Seems exciting for an early release.

Can it get much faster than something like Torch? I would think if CuDNN is doing most of the computation time it would be hard to see big improvements. Perhaps go the route of Neon and tune your GPGPU code like crazy [1, 2], or MXNet and think about distributed computing performance [3].
