Which of the following statements about DDR3's power consumption is true?

DDR3 memory is designed to be more power efficient compared to its predecessor, DDR2. One of the key advancements in DDR3 technology is its reduced voltage requirement. While DDR2 typically operates at 1.8 volts, DDR3 operates at 1.5 volts, leading to lower overall power consumption during operation. This decrease in voltage results in less heat generation, which is beneficial for energy efficiency and thermal management in systems utilizing DDR3 memory.

The design improvements reflect a favorable shift in power dynamics, allowing DDR3 to consume less power than DDR2 even when operating at higher speeds. This efficiency means that systems equipped with DDR3 can achieve enhanced performance without significantly increasing energy requirements, making DDR3 a more sustainable option for modern computing needs. This is why the statement about DDR3 using less power than DDR2 is true.
