Asus has rolled out an update for the Asus 1215P netbook which is similar to the Asus 1215B laptop except for the fact that the former comes with Atom N570 processor that runs at 1.66GHz clock speed. Another difference between the two is the use of Intel GMA 3150 for graphics.
In simple words, the graphics performance is going to suck in 1215P despite the processor upgrade. Earlier the 1215P was being bundled with the Atom N550 processor. However, graphic chip has not undergone any sort of change.
