In short, what is the advantage of having subpixel triangles?
Well, if you're interested in REYES and micropolygons, you can read it here, I suppose.

There is also stocasthic sampling article, but I think you need ACM account.
V3, if the GPU is Cell based they can surely split dicing and even shading... that would work quite well if I can add
Well, I haven't heard any revision from that patent, so I am just sticking to it, till they change it. Unless you have inside information, you SHOULD share
I oeiginally assigned slicing 'n dicing and Shading to the CPU thanks to its 1 TFLOPS of processing power, but if the GPU is indeed Cell based sharing this load should not be too complicated as Apulets/Software Cells are supposed to be able to migrate if there is need of additional processing power ( Intelligent multi-processing ).
Well you can do 50/50 or what ever I guess, but the shading of micropolygons, is the one that going to eat the available FLOP performance.
