Yes, I think this new 40nm Mobile GPU is actually the RV740.
The other GPU in the picture seems to be the RV770 used in HD4850 and HD4870, both mobile and desktop models.
Thus I think that
Mobility Radeon HD4850 and HD4870 have the RV770 with 800SP, 256bit memory and 55nm technology (the GPU on the left in the picture)
Mobility Radeon HD4830 and HD4860 have the RV740 with 640SP, 128bit memory and 40nm technology (the GPU on the right in the picture)
