Hi every body, Can anybody tell me , how to calculating the peak performance of magny core cpus? or tell me the IPC(Instruction Per Clock cycle) of opteron 6000 series? what about the intel 5600 family? such as x5670? Thanks.
Getting the instructions per cycle will be tricky (wikipedia + google?), but the GHz is easy (to get the IPC) You would have to consider the new generation Intel Turbo feature (if we're talking Intel here, cause I don't really know much about the AMD server CPUs). From what I know, that is some kind of automatic on-demand overclocking inside the CPU. For instance, the X5670 has a frequency of 2.93 GHz per core, but also a Max Turbo Frequency of 3.33 GHz per core. [See reference here]
