Use the DDR Memory Event pane to see the amount of transferred data for each Double Data Rate SDRAM (DDR) rank and memory event type. This pane is the basic part of the Bandwidth window that is available in the Platform Power Analysis viewpoint provided for the data collected with Intel® Energy Profiler on a target system. |
Note
Platform Power Analysis viewpoint is available as part of energy analysis. Energy analysis is provided by the Intel® VTune™ Amplifier for Systems only. Energy analysis collection is supported for target Android*, Windows* or Linux* devices.
Performance Metrics
The grid in the DDR Memory Event pane shows the amount of transferred data in megabytes (MB), for each Double Data Rate SDRAM (DDR) rank and memory event type. With columns for the following:
- Transferred data – this is the overall amount of data transferred
- Average bandwidth (MB/second) by Event Type – this shows the rate of transfer for each event type
- Transferred data by Component – this is the overall amount of data transferred, per component, for example, GFX, IO, or IA
- Average bandwidth (MB/second) by Component – this shows the rate of transfer for each component for example, GFX, IO, or IA
