intel_gpu_frequency - Manipulate Intel GPU frequencies
A program to manipulate Intel GPU frequencies. Intel GPUs will automatically throttle the frequencies based on system demands, up when needed, down when not. This tool should only be used for debugging performance problems, or trying to get a stable frequency while benchmarking. Intel GPUs only accept specific frequencies. The tool may, or may not attempt to adjust requests to the proper frequency if they aren't correct. This may lead to non-obvious failures when setting frequency. Multiples of 50MHz is usually a safe bet.
-e Lock frequency to the most efficient frequency. -g, --get Get all the current frequency settings. -s FREQUENCY, --set=FREQUENCY Lock frequency to an absolute value (MHz). -c, --custom Set a min, or max frequency "min=X | max=Y". -m, --max Lock frequency to max frequency. -i, --min Lock frequency to min (never a good idea, DEBUG ONLY). -d, --defaults Return the system to hardware defaults. -h, --help Show help. -v, --version Show version.
intel_gpu_frequency -gmin,cur Get the current and minimum frequency. intel_gpu_frequency -s 400 Lock frequency to 400Mhz. intel_gpu_frequency -c max=750 Set the max frequency to 750MHz
