But what is the use of deep CPU? It's all embarrassing parallel. I must be missing something here, because it always seemed to me that GPU were simply high end vector processors.
On the other hand, making a GPU that could do hardware raytracing (e.g. http://www.artvps.com/page/15/pure.htm ) That would be killer. And I agree, for something like that CISC would rule. However, it still seems to me that simpler is better in the case of a GPU. On a side note, SGI years ago had a graphics processor (Was it the SE series?) That understood native OpenGL. From what I understand, the hardware it'self was OpenGL. All the driver did was re-package the data a bit.

I think it says something about human nature that the only form of life we have created so far is purely destructive. We've created life in our own image.
