radeontop

Program that shows AMD Radeon GPU resource utilization

RadeonTop is a small utility which allows one to monitor the utilization of AMD Radeon GPUs starting from the r600 series and newer, using undocumented performance counters in the hardware. It displays the utilization of the graphics pipe, event engine, vertex cache, vertex group and tesselator, texture addresser and cache, the shader units, and more, both with a relative percent value as well as a colorful bar diagram (ncurses-based). Total GPU utilization is also valid for OpenCL loads; other values are only useful in GL loads.
