If you want to copy a video from a home computer to the portable phone, you must first convert this into a compatible codec for the player, which takes over the main processor. This is very flexible, but not really fast. Threesome on the other hand, the work performed by the GPU.


However, this requires a specially adapted software, which also is usually a fee. Microsoft wants to work with Windows 7, but apparently something about it, because the new operating system comes with a native application that allows

you to transcode a video to another codec on the GPU using drag and drop. It is not familiar to Nvidia's CUDA or ATI Stream on technology, but uses the new Compute Shader, so the feature on all the compute shader compatible GPUs (from Direct3D 10 support) is possible.


At the Computex show was the feature in a live presentation to an ION chipset from Nvidia. So you moved via drag and drop an HD video via Windows Explorer in Windows 7 on a Sony Walkman portable media player and transcoding was initiated directly by the GPU. The same work had a similar atomic system without GPU transcoding take on the main processor, which took longer for the same job as five times the ion system.
