So how does the new G80 archtechture work?

[Smartazz]

I understand last generations archtecture that both the pixel pipelines and vertex shaders are dependent on the core clock. But now there's a shader clock, these things called stream processors and still a core clock. This doesn't make any sense to me, why is there two seperate clocks, from my understanding the whole archtechture was changed for this generation of video cards. Can someone please give me a better understanding of how this works? Thanks in advance.

Read this. You will understand how G80 works. (well briefly)

Shader clock, core clock etc are simpyl called clock domains where the GPU is divided up into seperate sections where each section runs at a different frequency. In this case, the shaders are clocked t 1.35mhz but the rest of the chip (ROPs, TMUs) is clocked at 575mhz.

Actually for nVIDIA, the vertex shader ran at different speeds when it ran a 3d intensive app although this was later removed. (geforce 7 cards). The clock domain concept was used all the way back from NV40. With the release of G80, they took the concept much further.
