The thing is ... AMD will increase IPC 15-20% in their core progression. That is not their focus, however.
The goal of AMD is to run instruction-level code on the APU graphics engine as they fine-tune chip integration, on their way to SoC. That's probably also the reason you will not see desktop benchmarks prior to release in a few months. A few code optimizations have the potential for serious compute, making a benchmark from today useless.
The best examples would be Handbrake, Vegas, possibly CS6 Adobe, 3DSM, etc. Of lesser concern would be synthetics, but they want to put their best foot forward for rabid fanboy fodder (and potential brain aneurysms from Chipzilla).
