Power consumption and its relation with performance [14].
• increased operational time
• decreased acoustic noise of cooling
• decreased power supply cost
Power consumption plays a role in all domains, for example in Global
System for Mobile Communications (GSM) phones (standby time, operational
time, wireless video), data centers (some cities cannot accommodate more
data centers, due to the availability of electrical power), Magnetic Resonance
Imaging (MRI) gradients (faster switching of higher gradient fields, amplifier
costs, acoustics, and cooling are significant technical challenges), and desktop
PCs (where ...
