DDR3 vs. DDR4: What's the Difference?
Edited by Harlon Moss || By Janet White || Published on October 9, 2024
DDR3 is an older generation of RAM with lower speed and power efficiency compared to DDR4, the newer, faster, and more energy-efficient RAM standard.
Key Differences
DDR3 RAM, operating at lower frequencies, typically between 800 MHz and 2133 MHz, provides a reliable performance for its generation. In contrast, DDR4 RAM operates at higher frequencies, starting from 2133 MHz, offering greater bandwidth and faster data transfer rates.
In terms of power consumption, DDR3 RAM typically operates at 1.5 volts, making it less power-efficient compared to DDR4 RAM, which operates at 1.2 volts, thus reducing overall power usage and heat generation.
DDR4 RAM features improved reliability and faster data handling capabilities with its advanced bus architecture and data prefetching techniques. DDR3 RAM, while robust, lacks these newer technological enhancements.
Compatibility-wise, DDR3 and DDR4 RAM are not interchangeable due to different physical slots and key placements on motherboards. DDR4’s design allows for higher density modules, potentially offering larger capacity per stick than DDR3.
When considering upgrading or building a PC, DDR4 is generally the preferred choice for new systems due to its higher speed and efficiency, while DDR3 remains a cost-effective option for older systems.
