Hello, The number of committed instructions should be always the same! Because the real work done can be represented by committed instruction, and it is the same if one change the CPU frequency. What may change is the number of executed instructions (iew stage), because the dynamic behavior, i.e. the speculation, will be different with different CPU/cache freq ratio.
