We already know that AMD's next-gen Kaveri APU is coming to mobile systems. However, the chip will only fit into power envelopes ranging from 15W to 35W. For the tighter TDPs suited to tablets and convertibles, AMD has a couple of other, lower-power chips planned—and it announced them today at its APU13 event in San Jose.

These low-power APUs are called Beema and Mullins, and they're successors to today's Kabini and Temash offerings. AMD says they deliver twice the performance per watt of their predecessors and are scheduled for release in the first half of 2014.
