Show GPU utilization

$ radeontop

$ radeontop -c

$ radeontop -b [bus_number]

$ radeontop -t [10]

radeontop [-c|--color] [-b bus] [-t ticks]

radeontop displays real-time utilization statistics for AMD Radeon GPUs. It shows usage percentages for various GPU components including graphics pipe, shaders, texture units, and video decode/encode engines.
The tool reads from kernel debugfs interfaces and presents the data in a top-like format, useful for monitoring GPU workload during gaming or compute tasks.

-c, --color

Enable colored output

Select GPU by PCI bus number

Samples per second (higher = more overhead)

Dump data to file

Limit to n samples then exit

May require root privileges on some systems. Only works with AMD Radeon GPUs using radeon or amdgpu drivers. Older GPUs may not support all metrics.

radeontop was created by Chris Blaas to provide GPU monitoring for AMD graphics cards on Linux, similar to nvidia-smi for NVIDIA cards.
