DDR3 is a type of computer memory technology that refers to the third generation of Double Data Rate synchronous dynamic random access memory (DDR SDRAM). DDR3 is capable of delivering higher bandwidth as compared to DDR2 thanks to a 8-bit prefetch buffer that increases the data transfer rate. DDR3 is also engineered to operate at a lower voltage rating (1.5V) than DDR2, thus enabling energy-efficient operations. Additionally, DDR3 memory modules have a higher maximum memory capacity and transfer rate compared to DDR2, thereby making them more efficient in memory-intensive tasks. Overall, DDR3 is a high-performance memory technology that’s widely used in modern-day computers for robust operations and faster computational speeds.
