Out-of-Order Execution Benefit Calculator

Estimate the IPC improvement from out-of-order execution. OOO CPUs reorder instructions to avoid stalls from data dependencies, improving utilization of execution units

Each component has a specific meaning:

• Out-of-order execution — The out-of-order execution recorded for the scenario being assessed.

Note: Interpret the out-of-order execution result against the thresholds and context described above.

Enter the out-of-order execution for the scenario you are assessing. Estimate the IPC improvement from out-of-order execution. OOO CPUs reorder instructions to avoid stalls from data dependencies, improving utilization of execution units. Use the out-of-order execution result to inform your calculation.
