It's the same RV770 GPU in both 4850 and 4870...The only difference is the clock of GPU and memory in those 2 models.
So to recap once again:
RV700 800SP(160x5),40TMUs,16ROPs
Radeon 4850:RV770 clocked @625Mhz,993Mhz for DDR3 memory
Radeon 4870:RV770 clocked @750Mhz,993Mhz for GDDR5 memory(acting effectively as 3.6Ghz DDR3).
