Reading and reading appear the situation it's a bit complex.
For video editing Intel Quick Sync make some difference, and OpenCL it's the new standard. Support appear to be vary, with some sw benefiting more from CPU than from GPU, some others specialized on workstation gpus such as Nvidia Quadro or ATI FirePro.
I need to balance 3DMark performance for my realtime CE3 design, OpenCL for video rendering, 3D output support to my 3D TV set.
Considering that what can be a "intelligent" choice?
