# --------------------------------------------------------------------------
#
# Very simple script to grab AMD GPU information, using `lm-sensors`.
# Output contains the GPU edge, junction and memory temperatures, in Celcius,
# along with the current PPT watts value.
# Usage: ./amd_gpu.sh {optional sensors chip id}
