CUDA and OpenCL - dead end or the future?

We deal already for some time with the acceleration by GPU and ask ourselves frequently whether the graphics card is a co-processor effect the future, or rather a dead end in the video editing . The developers of graphics-magick definitely see the latter and not without arguments. In fact, there are some effects algorithms that can be accelerated significantly by the GPU. But equally there are many effects that are on a GPU is very inefficient to implement. And as long as one does not effect the GPU can outsource every video, a GPU is just not a universal solution, since a recourse to the main memory the performance gains back to robbing. The developers also believe that with the integration of the GPU into the CPU ( what so directly as development is imminent), also the end of OpenCL and CUDA will be ushered in, as it will provide simple compiler automatically optimized for an appropriate optimization. And since the number of processor cores on the CPU will also grow rapidly, it is set to future-proof their view on the multi-CPU horse.
