The iPod touch 5th gen, the iPad mini and the 2012 iPad 2 all have the 32nm A5.
The 4S did not the receive the new chip after it was reduced to it's lower price point after Sept 2012.
(The ATV has had two versions of the 32nm A5 - both single core.)
Thanks. What is ATV ? So the iPod touch had better battery life than iPhone 4S even if it has a smaller battery ?
A5 is a not a dual core on iPad mini and iPhone 4S ?
