How many instructions per cycle do amd k8 (preferably amd turion x2 64, if it matters) CPUs have? I looked everywhere and I can't find it.

A:
It's quite a complicated question, how many RISC instructions (after translation of the original CISC instructions of the x86 legacy) a processor can execute in parallel depends on the instruction itself, whether there are pipeline dependencies and free ALU units.
Chances are you can find a list of how many cycles each specific instruction needs on the AMD website, then the dependency rules, Intel used to publish those specifications and that should normally be public. Interpreting it with modern CPU's is another matter.
