Interestingly IPCs are also used to verify new chipsets in embedded companies. Run the same code with newer generation chipset and see if IPC is better than the previous. IPCs are one of the main criteria if the new chipset is a hit or miss (others are power..)

Interesting. That must get messed up whenever they change the architecture in a major way, eg, Intel Skylake going from 4-wide to 5-wide.

AFAIK this is used in embedded chipsets that come with preloaded software like modems.
