Notes:
1. These values specify the power consumption at nominal voltage and apply to all valid processor bus frequencies and
2. Typical power is an average value measured at the nominal recommended core voltage (V
3. Thermal power is the average power measured at nominal core voltage (V
4. Maximum power is the maximum power measured at nominal core voltage (V
