AMD confirmed it a few days ago the 4870 has 800.

People have the 4850 out in the wild. I think they should know whats up shouldn't they? Also more and more info is coming out all the time. AMD did a very good job in fooling everyone about the capabilities of their new cards.

Look, the 4850 has a TDP (thermal design power)  of 110W. If you really think a card with 160 shaders (800 stream processors) can run at those frequencies and blow less than 110W, then you are extremely naive. Also learn how marketing people calculate to state the 1.2 Teraflop performance of the R700 (hint: essentially the same way memory throughput is touted by the same people).

So once again, the 4850 has 96 shaders (or 480 stream processors if you like high numbers).

It is aprox the same size as the g92 with 120 shaders @ 55nm.

"Taking those ChipHell numbers, HD4850 compared with HD3870, per clock:

• Call of Juarez - 187%
• Call of Duty - 230%
• Crysis - 181% "

More than twice the performance in some applications and more than twice the shader power.
