Read leveling in ddr4
WebCompared to DDR4 at an equivalent data rate of 3200 megatransfers per second (MT/s), a DDR5 system-level simulation example indicates an approximate performance increase of 1.36X effective bandwidth. At a higher data rate, DDR5-4800, the approximate performance increase becomes 1.87X—nearly double the bandwidth as compared to DDR4-3200.
