ATI Stream & Nvidia CUDA

9287-amdstreamcosttime

There are many great things that can make your PC faster… but wait. There is a second powerful processor in your machine already that you might not be aware of. It’s the GPU of your graphics card. ATI & Nvidia are going the right way. There are so many things the GPU can do. I’m encoding quite a lot of videos lately. Just check the chart above. Lower is better and notice the price of the AMD platform. This is what I call vaule. Physics or Artificial Intelligence in games – why do they have to use one of the cores of a Multi-Core-CPU? The GPU can provide the rendering power for that.

Edit:

Q: Why are reviewers seeing so little GPU processing during transcoding?
A: The ATI Video Converter uses the GPU for only a portion of the video encoding. Specifically, the GPU currently offloads only the motion estimation portion of the encoding pipeline which is the most compute intensive part of the encoder. The GPU is particularly well-suited for this task. Given that a fixed workload is being offloaded to the GPU the load on the GPU may be relatively low or high based on the specific model of GPU.

Seems that ATI’s Stream got a little bit in bad light becasue it’s using only little GPU processing during transcoding but I guess that problems will be solved soon:
