I can't tell if they did use CUDA or not to test the nVidia GPUs. If not, since they used Intel TBB on the Xeon Phi's, the benchmark would be obviously flawed.

I can't tell if they did use CUDA or not to test the nVidia GPUs. If not, since they used Intel TBB on the Xeon Phi's, the benchmark would be obviously flawed. Also, perhaps the part where they used newer, more powerful CPUs when testing the Phi's had something to do with the performance jump.
