"Radeon HD 4870 and Radeon HD 4850 will both have a whopping 800 Shaders. T

Who invents such bullshit news? The R770 is still based on R670 technology, there simply is no space for such massive amounts of transistors (with doubled texture units, space is even more restricted). The R670 has 320 stream processors and the R70 is supposed to have 320 as well (some rumours talk about 480 processors). The new design R870 seems to go with 40 or 45nm technology, and wild rumours have it at  1000 stream processors.  

It was kindof confirmed a few days ago. The rumors all pointed to 480 SP but the consensus shifted to 800SP when some evidence popped out.

The RV670 is just a shrink of the R600die with a few tweaks here and there, but we never got any die shots of the R600 so we don't know how big each component of the chip is. Also the chip is larger, around the same size as a shrunk G92b is expected to be and they are using the high performance 55nm process at TSMC which may have a higher transistor density.

The consensus at B3d which has some very intelligent people, many of whom have inside knowledge in the industry or are a part of it seems to agree with the new rumors that leaked out.
