So my sister needs a new laptop, we want to move into a tablet 2 in 1 with windows 8.1 ( Aiming for a transformer t100 or lenovo miix210). What are the differences in performances between an Intel Atom, a celeron and a AMD vision A4.These last both manufactured by toshiba. For the things I have read about SOC and the atom, they maximize the battery and generate little heat (tablet's doesn't use a fan). But in all reviews I checked about tablets they only mention ARM and the intel, I have never heard about big 2in1 (more than 11") running celeron or AMD Vision. Do thjey offer the same (or better) life battery or pruduce little heat?
