There are some leaked benchmarks comparing the current AMD Llano 35W laptop APU against the next gen Trinity 35W chip with Piledriver cores. On the CPU side Trinity shows about a 5% increase in floating point and a 39% increase in integer performance. Both are operating at the same TDP with 32nm silicon and the next gen cores are able to operate at higher efficiency. The Trinity chip also has a bigger GPU leaving less TDP for the CPU.
The older Llano part uses four 1.4-2.4GHz Magny generation cores, Abu Dhabi with pile driver should finally bring increased efficiency to 4p G34, breaking 1000ppd/w with 16 core chips.
