What is the difference between DDR3 and DDR4 RAM?

DDR3 and DDR4 are two different generations of RAM (Random Access Memory) used in computers. The main difference between DDR3 and DDR4 RAM lies in their speed and efficiency. DDR4 RAM offers higher data transfer rates and speeds compared to DDR3, resulting in faster performance and improved multitasking capabilities. DDR4 RAM also operates at a lower voltage, reducing power consumption and heat output, leading to better energy efficiency and improved overall system reliability. Another key difference is the physical design and compatibility; DDR4 RAM modules have a different pin configuration than DDR3, making them incompatible with each other. Therefore, upgrading from DDR3 to DDR4 RAM typically requires a motherboard that supports DDR4 technology. Overall, DDR4 RAM provides several advantages over DDR3, including better performance, improved energy efficiency, and higher capacity options.
