From outside, the Asus Eee 1201PN looks like the Eee PC 1201N or the AMD-powered Eee 1201T, but the difference lies inside as the the new 1201PN packs the new processor and graphics. The Asus 1201PN comes with 1.66GHz Atom N450 processor due to which the performance is not at par with the Asus 1201N.
That said, the second gen Nvidia ION chipset does provide higher performance over the first generation, especially in the 3D performance department. Also, it can handle all 1080p videos with ease. By switching to the single core processor, Asus has somehow managed to strike a balance between good battery life and decent performance. [via laptopmag]
