--table Output table of basic GPU details
--pstates Output pstate tables instead of GPU details
--ppm Output power/performance mode tables instead of GPU details
--clinfo Include openCL with card details

## GPU Type Dependent Behavior
AMD GPU's compatible with the amdgpu open source drivers are of three different types in terms of how frequency/voltage
is managed. GPUs of Vega10 and earlier architecture rely on the definition of specific power states to determine
