MIPS = Instruction Count / Time * 10^6

= Clock Rate / CPI * 10^6

• machines with different instruction sets ?

• programs with different instruction mixes ?
  • dynamic frequency of instructions

• uncorrelated with performance

MFLOP/S = FP Operations / Time * 10^6

• machine dependent

• often not where time is spent
