I concur about missing MXnet, but it's noteworthy that TF is the fastest for the convolutional nets on GPU -- a case many care about, and one covered best by Soumith's benchmarks. (Full disclosure: I help develop TF part time).

Clearly room for optimizing the CPU versions of things. That may be Eigen. Intel now has a preview out of their DNN toolkit -- I wonder if we'll see the same speed convergence as we did with CuDNN.
