6.3 Thermal Design Power
The thermal design power is defined as the power dissipated by the GPU and HBM
while running a selected application at up to the maximum recommended operating
temperature, and is measured as the maximum average power in a five-second
moving window.
The thermal design power is intended as a recommended thermal design point; it is
not an absolute maximum power under all conditions.
"Vega 10" has up to eight defined Dynamic Power Management (DPM) states, from
DPM_0 to DPM_7, in ascending order of performance and power. When a graphics-
demanding application (such as a game) is running, AMD's PowerTune constantly
switches GPU among the states based on run-time analysis of GPU activities, power
and thermal conditions. The effective power/performance depends on the percentage
of time spent in each state.
The data are targets only, and are subject to change.

6.4 Thermal Diode Characteristics
For "Vega 10", the ideality factor of the on-die thermal diode varies significantly with
temperature and sourcing current. If a design chooses to use the GPU's on-die
