Yes thanks to a voluntarly crippled 6620...
From the pages you quote :
If we're to believe that then it confirms what I said earlier that the current CPUs are so crippled in single-threaded performance that a boost there means a boost also in IGP performance. This is also why I'm saying that AMD will need to balance out CPU and GPU improvements for Trinity because if they focus only on the IGP they won't have much of a performance improvement because of the CPU bottleneck.
Trinity, and by extension Piledriver, should improve IPC somewhat, finally bringing AMD to the IPC they had 3 years ago with Stars/K10.5.
Given the existing bottleneck AMD has to cope with, I'd expect the overall improvement will be more balanced than what Intel did with Ivy Bridge where they improved the CPU very little and the IGP a lot, but at the same time the overall improvement in performance combining both should be similar. A 15-20% CPU improvement and 15-20% IGP improvement sounds like what AMD should be aiming at if their APU engineers are smart. This compares to Intel who already had an incredibly powerful architecture and therefore got away with small (5-10%) CPU improvements but needed bigger IGP improvements (35-40%).
BTW, manufacturers won't use DDR3-1600 modules, so don't expect an improvement there from their part--AMD will need to have a big improvement in CPU memory bandwidth, cache latency and bandwidth if they also want to remove that bottleneck out of the equation.
