A8-3870K (Llano, 1st generation APU), running Ubuntu 13.10, benchmarks via BOINC Manager:
2461 floating point MIPS (Whetstone) per CPU
15793 integer MIPS (Dhrystone) per CPU

This Llano is made out of four K10 cores, each having both a FPU (Floating Point Unit) and an ALU (Arithmetic Logic Unit)

A10-5700 (Trinity, 2nd generation APU), running Lubuntu 13.10, benchmarks via BOINC Manager:
2450 floating point MIPS (Whetstone) per CPU
9513 integer MIPS (Dhrystone) per CPU

This Trinity is made out of two Piledriver modules, each having two integer cores and a shared floating point unit. For some reason the integer performance of Bulldozer, Piledriver -and now Steamroller too- leaves much to be desired as compared to the older K10 integer units....and quite a lot of BOINC projects make heavy use of the integer performance of your CPU core(s).

Note that the BOINC benchmarks of -at least AMD- CPUs under Linux are higher than those of a likewise CPUs under Windows....

It almost looks like a Bulldozer module isn't made out of two integer cores and a shared floating point unit, but the other way around: Two floating point units and a shared integer unit! How else can the differences between the Llano and the Trinity be explained?
