radeontop is a command-line utility that is used to show the utilization of AMD GPUs. It provides real-time monitoring of the GPU’s performance, including the GPU temperature, frequency, memory usage, and power consumption. This information can be useful for diagnosing performance issues, optimizing GPU usage, and monitoring system health.
radeontop requires root privileges to access the GPU performance data, so it may not be accessible to non-administrative users depending on your system configuration.
radeontop Command Examples
1. Show the utilization of the default AMD GPU:
# radeontop
2. Enable colored output:
# radeontop --color
3. Select a specific GPU (the bus number is the first number in the output of `lspci`):
# radeontop --bus bus_number
4. Specify the display refresh rate (higher means more GPU overhead):
# radeontop --ticks samples_per_second
Summary
radeontop is an open-source tool that is available for Linux systems. It supports a wide range of AMD GPUs and provides a straightforward way to monitor GPU performance from the command line. The tool is especially useful for gaming, mining, or other GPU-intensive applications, where it can help to identify bottlenecks and optimize performance.
