## Expected time-steps/hour

The following table outlines expected performance in terms of the number of time steps per hour
(rounded to the nearest hundred) for various problem sizes (grid cells) and hardware for an inviscid, 6-equation (`model_eqns' : 3`), 3D simulation.
CPU results utilize an entire die.
The following table outlines expected performance in terms of the number of time steps per hour (rounded to the nearest hundred, higher is better).
A 3D inviscid, 6-equation (`'model_eqns' : 3`) problem is solved for various problem sizes (grid cells) and hardware.
CPU results utilize an entire processor die.

If `'model_eqns' : 3` is replaced by `'model_eqns' : 2`, an inviscid 5-equation model is used.
The following table outlines expected performance in terms of the number of time-steps per hour (rounded to the nearest hundred) for various problem sizes and hardware for an inviscid, 5-equation,
3D simulation.
CPU results utilize an entire die.
The below table shows expected performance via the number of time steps per hour (rounded to the nearest hundred) for various problem sizes and hardware for an inviscid, 5-equation, 3D simulation.
