Also, the other changes that hopefully we see this generation is the dual triangle setup which will help with tessellation.

All of that in under 400mm2 is amazing, again if it is all true which we will have to wait at least a few more weeks until we get more leaks/info.
since ATi uses a 16 wide SIMD it should be 64 sp's per core for SI. you could have 448sp's or 512sp's. 480 is xtremely unlikely.

essentially that is what they have now but with some baggage. each register is still going to be 128bits with 12 read and 4 write ports. this is about 45% of the shader unit and it contributes a lot of power.
