Check out this comparison between the older K10.5 A8-3500m against the newer trinity A10-4600m.
We see a whopping 265% increase in performance!! I suspect this could be faked due to suspicious numbers comparing to my own results here , but only time will tell for sure! This looks extremely promising!
EDIT: Here we see an official AMD slide mentioning a 50% gain in computing performance (on average) moving from the A8-3500m (K10.5) to the A10-5600m (Piledriver) with 12.5 hours idle , and over 7.25 hours of battery life with use!! This is simply amazing!
