DDR5, the successor of DDR4, was developed to deliver performance improvements when system designers felt rising pressure from continuous technological advancements—the memory bandwidth being unable to keep pace with newer processor models with escalated core counts. While previous generations focused on reducing power consumption and were driven by mobile and server applications, DDR5's primary driver needed more bandwidth. Compared to DDR4 at an equivalent data rate of 3200 mega transfers per second (MT/s), a DDR5 system-level simulation example indicates an approximate performance increase of 1.36X effective bandwidth. The approximate performance of DDR5-4800, at a higher data rate, increases to 1.87X—nearly double the bandwidth as compared to DDR4-3200. Micron's DDR5, driven by data rates up to 6400 MT/s and key architectural improvements, pushes potential system bandwidth even higher.
