As clock rates increased in early Intel processors, power _______

• increased

• decreased

• disappears

The ________ Intel processor consumed the most power.

• 2004

• 2016

• 1989

Which improvement has bigger impact on power?

• 25% reduction in voltage

• 25% reduction in frequency switching

Voltages have decreased from 5V to 1V. Why don't manufacturers continue to lower voltages to reduce power consumption?

• Further lowering of voltage results in transistor leakage

• Voltage has no impact on power
