Kinect uses less than 10 per cent of Xbox 360's processor

Anyway the interesting thing is that Kinect uses a decent whack of GPU performance as well. It is a legitimate GPGPU application and deserves credit for that alone, especially on a DX9 GPU. Its probably the equivalent effort to 'maximising teh Cell' if you go by estimates that GPGPU is about 5* harder than Cell programming.

huh? The image processing required basically yelled "use the shaders in the GPU" right from the start, and I think people know how to write shader programs on Nvidia GPUs. getting the Cell to talk with the SPUs and the GPU is a lot harder in all likelihood.

Unlikely. Shader programming is significantly tougher than SPU programming and requires a lot of finese, especially when other programs are running sequentially or at the same time. Epic attests to the same thing as well I believe that it went something like this:

1: X86

2. PPC.

5. SPU

10. DX10 GPU

In terms of quantity of money needed to be thrown at each problem.

However this is a DX9 GPU which doesn't benefit from any of the
