-For prediction the speedup is around 2-3x for varying number of components and features. For the number of samples the cross-over point is around O(10^4) samples.
+For prediction the speedup is around 5-6x for varying number of components and features and ~50x speedup on the GPU. For the number of samples the cross-over point is around O(10^3) samples.

-For training the speedup is around >10x on the same architecture and close to 100x speedup on the GPU. However there is no guarantee that it will converge to the same solution as Scikit-Learn. But there are some tests in the `tests` folder that compare the results of the two implementations which shows good agreement.
