GPU EUs Idle
The metric GPU EUs Idle represents the percentage of time when the GPU execution units (EUs) were idle. An EU is idle when it is neither actively executing shader instructions nor stalled trying to execute shader instructions.
- If GPU EUs Idle is 50, it means that EUs where idle for 50% of the rendering time for selected ergs.
- If GPU EUs Idle is 0, it means that the EUs were either active or stalled for the entire duration of the rendering time for the selected erg.
If the GPU EUs Idle percent is significantly higher than 0%, this indicates that there are stalls elsewhere in the rendering pipeline.
