GPGPU is already a standard in gamedevelopment for creating great looking visual effects. Offloading CPU heavy tasks is common too, just not as much. Some tasks can´t be parallized that easily or are not always that much faster calculated on the GPU (that is, if the task isn´t predestinated to be computed in parallel and has a lot of synchronization work to be done).

If cloud-based gaming becomes the standard in the future, the ps4 may get the short end of the stick. Offloading CPU tasks on the cloud would free-up a lot of other ressources. Offloading CPU tasks on the GPU is limited in some way or another and not always the best solution.

Anyway, this is just talk atm. Imo cloud-based gaming has still a long way to go.

GPU's are alot faster than CPU's their is just less specialized stuff the GPU can do.

That being said, tasks that can be offloaded from the CPU to cloud, can be offloaded to the GPU, freeing up cloud compute options.

Thus even if cloud-based gaming becomes the standard, PS4 would be able to do both which is still an advantage to only being able to do one. The disadvantage being that MS's Network of Servers will probably be more adapted then modified-gaikai.

The limitations of GPU far exceed the limitations of cloud, espcially latency and the whole Speed of Light thing.
