Power

Total APU Power

Average APU Power for the sampling period, reported in Watts. This is an estimated consumption value which is calculated based on APU activity levels.

 

CPU Compute Unit 0 Power

CPU Compute Unit 1 Power

Average CPU Compute Unit Power for the sampling period, reported in Watts. This is an estimated consumption value which is calculated based on APU activity levels.

 

iGPU Power

Average Integrated-GPU Power for the sampling period, reported in Watts. This is an estimated consumption value which is calculated based on APU activity levels.

 

PCIe-Controller Power

Average PCIe-Controller Power for the sampling period, reported in Watts. This is an estimated consumption value which is calculated based on APU activity levels. This value does not include the power consumed by PCIe devices connected to the PCIe bus.

 

Memory-Controller Power

Average DDR Memory-Controller Power for the sampling period, reported in Watts. This is an estimated consumption value which is calculated based on APU activity levels. This value does not include the power consumed by the memory DIMMs.

 

Display-Controller Power

Average Display-Controller Power for the sampling period, reported in Watts. This value refers to the APU's internal display controller which may be used in notebook and embedded configurations. This is an estimated consumption value which is calculated based on APU activity levels. This value does not include the power consumed by the display.

 

Cumulative APU Power

The accumulated energy consumed by the APU throughout the profile session. Reported in Joules.

Available only in the command line tool

Cumulative Compute Unit 0 Power

Cumulative Compute Unit 1 Power

The accumulated energy consumed by the CPU Compute Unit throughout the profile session. Reported in Joules.

Available only in the command line tool

Cumulative iGPU Power

The accumulated energy consumed by the APU’s Internal GPU throughout the profile session. Reported in Joules.

Available only in the command line tool

dGPU power

Average Discrete-GPU Power for the sampling period, reported in Watts. This is an estimated consumption value which is calculated based on dGPU activity levels.

The dGPU family name is prefixed with this counter name.

Frequency

CPU Core 0 Average Frequency

CPU Core 1 Average Frequency

CPU Core 2 Average Frequency

CPU Core 3 Average Frequency

Average CPU Core Frequency for the sampling period, reported in MHz. This is the Core Effective Frequency (CEF). The core can go into various P-States within the sampling period, each with its own frequency. The CEF is the average of the core frequencies over the sampling period.

 

iGPU Average Frequency

Average Integrated-GPU Frequency for the sampling period, reported in MHz.

 

dGPU Average Frequency

Average Discrete-GPU Frequency for the sampling period, reported in MHz.

The dGPU family name is prefixed with this counter name.

CPU Core 0 Frequency Histogram

CPU Core 1 Frequency Histogram

CPU Core 2 Frequency Histogram

CPU Core 3 Frequency Histogram

Histogram of CPU Core Effective Frequency (average frequency for the sampling period).

Available only in the command line tool

iGPU Frequency Histogram

Histogram of Internal-GPU Effective Frequency (average frequency for the sampling period).

Available only in the command line tool

Temperature

CPU Compute-Unit 0 Measured Temperature

CPU Compute-Unit 1 Measured Temperature

Measured CPU Compute Unit Average Temperature, reported in Celsius. The reported value is normalized and scaled, relative to the specific processor's maximum operating temperature. This value can be used to indicate rise and decline of temperature.

 

iGPU Measured Temperature

Measured Integrated-GPU Average Temperature, reported in Celsius. The reported value is normalized and scaled, relative to the specific processor's maximum operating temperature. This value can be used to indicate rise and decline of temperature.

 

dGPU Measured Temperature

Measured Discrete-GPU Average Temperature, reported in Celsius. The reported value is normalized and scaled, relative to the specific processor's maximum operating temperature. This value can be used to indicate rise and decline of temperature.

The dGPU family name is prefixed with this counter name.

CPU Core State

CPU Core 0 P-State

CPU Core 1 P-State

CPU Core 2 P-State

CPU Core 3 P-State

CPU Core P-State at the time when sampling was performed.

 

Other counters

Core 0 Process ID

Core 1 Process ID

Core 2 Process ID

Core 3 Process ID

Process Id of the process that was executed by the CPU core at the point in time when the core was sampled.

Available only in the command line tool
